International organization’s compendium on ICT and Education includes work by academic of Universidad de Santiago

International organization’s compendium on ICT and Education includes work by academic of Universidad de Santiago

  • The Latin American Network of Educational Portals included the work done by Dr. Juan Silva, director of the Center for Research and Innovation in Education and ICT (CIIET, in Spanish), in a publication that gathers together renowned Latin American experts in this field.

Professor Juan Silva Quiroz’ work was selected by the Latin American Network of Educational Portals (Relpe, in Spanish) to be included in a recently published compendium that gathers several papers and reflections on the use of technologies in the educational process. The name of the book is “Mirada Relpe: Reflexiones iberoamericanas sobre TIC y Educación” (Relpe’s view: Latin American reflections on ICT and Education), and it started to be developed in 2011.

Dr. Silva reflects on the relation between Information and Communication Technologies (ICT) and education policies, particularly in the incorporation of these ICT in the Early Teaching Training (FID, in Spanish) process, as he considers them a determining factor to improve the quality of education, by training professionals in this field and enabling them to understand these tools and implement them in the classroom.

Relpe’s initiative has the purpose of establishing a regional view on how technologies are understood in education.

In the same way, professor Silva highlights the international significance of this initiative, as it provides different points of view on this matter. “Two of us wrote about ICT in teacher training; other expert wrote about videogames and another one wrote on Personal Learning Environments (PLE), etc. It is then a wide variety of work subjects or problems about technology and education presented, referenced or argued by leaders in this field,” he said.

He also added that the book includes some subjects that should be addressed since university education, particularly, in teacher training.

Potential of ICT tools

Regarding the advantages of using collaborative tools like ICT, professor Silva said that most of the teachers, especially at university level, do not see the potential of ICT tools, in terms of having opportunities to share knowledge at a national and international level. Assignments and presentations, he explained, can be modified and improved and will always be available in Prezi, blogs and Wikis, for example, under the logic of Web 2.0.

He also said that these participative and collaborative models are very useful, especially in teaching, which is normally perceived as an individualistic work. “In the traditional model, the teacher presents knowledge and students receive it. On the other hand, in a collaborative model, the teacher acts as a facilitator, as a mediator, and students have an active role in their knowledge- building process,” he added

Nowadays, Dr. Silva is part of a commission set up by the Ministry of Education to address the inclusion of ICT in the training of future teachers, and soon he will publish a book about different experiences of using ICT in early teacher training in Latin American, thanks to a teaching innovation project of the Academic Vice Presidency and sponsored by the Ministry of Education’s Center of Education and Technology (CET, in Spanish).

Researcher gave presentations in Italy and Spain on the progress of her study about school socioeconomic segregation

Researcher gave presentations in Italy and Spain on the progress of her study about school socioeconomic segregation

  • In order to have feedback from her European peers, Claudia Córdoba, professor at the Department of Education of Universidad de Santiago, presented the progress of her study “Analysis of the school socioeconomic segregation in primary education” (Fondecyt Initiation Project 11130149) at Universitá degli Studi di Cagliari (Sardinia, Italy) and at the Complutense University of Madrid (Madrid, Spain). The study analyses the socioeconomic segregation in geographically close schools, considering residential segregation, family preferences, and the barriers imposed by schools with regard to payments and student selection.

 

In September, Claudia Córdoba, professor at the Department of Education of Universidad de Santiago de Chile presented the progress of her research study “Analysis of the school socioeconomic segregation in primary education (Fondecyt Initiation Project 11130149)” at two European universities.

Her first presentation was at Universitá degli Studi di Cagliari (Sardinia, Italy), on September 21st, and then she showed her work at the Faculty of Education of the Complutense University of Madrid (Madrid, Spain), on September 24th.

On both occasions, she presented the progress of her work in the context of the project that she leads, receiving feedback and suggestions for its continuation.

The study is focused on the phenomenon of socioeconomic segregation in geographically close schools, considering three concurrent factors: residential segregation, family preferences, and the barriers imposed by schools with regard to payments and student selection.

“Doubtlessly, in our country, the phenomenon of school segregation is stronger than in countries like Italy and Spain; however, it is always interesting to appreciate that some dynamics can also be noticed in school systems which are very different from the Chilean one,” Professor Córdoba said.

In this regard, some Spanish professors said that, in their country, it is possible to notice big differences in the social composition of the student body of public schools, even when they are geographically close.

In the case of Italy, the families there also seek to ensure that their children learn some skills that can give them an advantage over their peers (learning English, for example), and that it is possible to see big differences in the socioeconomic composition of the student body in different types of high school.

Some of the preliminary results were particularly interesting, For example, the fact that children in Santiago seem to travel much longer distances than the ones travelled by children in Madrid or Cagliari.

Water decontamination through electricity and solar energy

Water decontamination through electricity and solar energy

  • In the context of a series of seminars ran by the Department of Environmental Sciences of the Faculty of Chemistry and Biology, Dr. Ricardo Salazar informed about the scope of the research on treating waters contaminated by textile and pharmaceutical industry effluents through electrochemical methods.

In order to inform about the progress made by the Laboratory of Environmental Electrochemistry’s research group, Dr. Ricardo Salazar gave the presentation “Elimination of persistent organic pollutants in water by using electrochemical methods,” in the context of a series of seminars organized by the Faculty of Chemistry and Biology.

The activity gathered together academics and students who learned about the research being conducted at Universidad de Santiago with regards to eliminating organic compounds in water through advanced oxidation electrochemical processes. Particularly, the presentation referred to the Fondecyt project called “Degradation of dye-containing effluents from textile industry through electrochemical oxidation,” in which Dr. Salazar is the responsible investigator.

The objective of the study is to decontaminate waters that contain dyes and additives by means of electricity and solar energy, avoiding the use of chemical reactants.

“Today, we are working on the treatment of real samples of textile industrial effluents. To do so, we have built a pilot plant to treat larger volumes of contaminated water. We are also testing new electrodes for the process and we have extended the contaminant spectrum to pharmaceutical industrial effluents,” Dr. Salazar says about the status of the study, in which Dr. Julio Romero, from the Faculty of Chemical Engineering of Universidad de Chile, takes part as a co-investigator.

SERC Chile

Thanks to his achievements in this field, Dr. Salazar has accepted an invitation to take part as an investigator in a FONDAP project for the Chilean Solar Energy Research Center, SERC Chile, an agency that seeks to become a world leader in solar energy scientific research, with a particular emphasis in developing the potential of the Atacama Desert, Chile.

“I was invited as an associate investigator in the research line of “Solar Water Treatment”, which is coordinated by Dr. Lorena Cornejo Ponce, tenured professor at the Escuela Universitaria de Ingeniería Industrial, Informática y Sistemas (EUIIIS) of Universidad de Tarapacá. The idea is to contribute to the treatment of persistent organic pollutant-containing waters and their treatment through Solar photoelectro-Fenton degradation”, he says.

Researchers at Universidad de Santiago revealed that the extension of the hole in the ozone layer reached record levels in December

Researchers at Universidad de Santiago revealed that the extension of the hole in the ozone layer reached record levels in December

  • After four weeks of work in the Antarctica, Dr Raúl Cordero and Dr Alessandro Damiani, both researchers at the Department of Physics of Universidad de Santiago de Chile, were able to confirm that the extension of the hole in the ozone layer over the Antarctica reached more than 10 million km2 in December 2015, i.e. more than twice the average of that period in the past three decades.

The measurements were carried out during a campaign in the Antarctic Circle in the context of the Antarctic Scientific Expedition of the Chilean Antarctic Institute (Inach, in Spanish). Dr Raúl Cordero and Dr Alessandro Damiani, both professors at Universidad de Santiago de Chile, were part of the expedition.

The ozone measurement campaign at the Antarctica started on November 15th and it continued until mid-December. Four researchers at Universidad de Santiago travelled to the heart of the White Continent, where about 600 kg of the best radiometric equipment available were sent.

The expedition was supported by Inach, what allowed the researchers to work at “Unión Glacier” Joint Polar Research Station located at 79 degrees South latitude, at about 1000 from the South Pole.

Constant monitoring

In spite of the negative results of this year, Dr Cordero expects that a process to recover the ozone layer starts in the short term, as a result of the actions taken worldwide to reduce the emissions of polluting gases. However, the information gathered highlights the need of adopting mitigation policies and conducting a constant monitoring of the area.

According to Dr Cordero, “the ozone layer depletion is mainly caused by the presence of ‘ozone destroying” chemicals in the polar stratosphere. These substances are generated by the industrial activity in mid-latitudes.”

Although these substances are everywhere in the planet, high latitudes are the most impacted areas by the layer depletion or destruction, particularly the Antarctica. During the southern spring, this area is affected by a massive destruction of the stratospheric ozone as a result of the particular weather conditions there.

According to the researcher, the ozone depletion process between September and December is favored by the low temperatures in the Antarctic stratosphere and by the Antarctic polar vortex that prevents the ozone from other latitudes from closing the hole.

“When temperatures increase at the end of spring, the ozone massive depletion stops and the weakening of the polar vortex allows the ozone from other latitudes to close the hole. The bad records this year are probably the result of unusually low stratospheric temperatures during last spring,” Dr Cordero said.

Recovery of the ozone layer

In spite of the negative results of this year, Dr Cordero expects that a process to recover the ozone layer continues until the middle of this century due to the actions taken worldwide to reduce the emissions of polluting gases. However, the information gathered highlights the need of adopting mitigation policies and conducting a constant monitoring of the area.

It is also worth to mention that this study included comparisons with databases of other months. According to this, the hole in the ozone layer reached 28 million kmin October, the fourth highest record since the satellite data is available. 

Dr Cordero also highlights the relation between ozone depletion and climate change. “The changes in the hole in the ozone layer could affect the energy balance of the Antarctica. Ozone depletion or exhaustion has affected the temperature of the stratosphere and it correlates with wind and surface temperature variations detected in the Antarctica in the past decades. Therefore, a better understanding of the relation between climate change and the hole in the ozone layer is required. This is the ultimate goal of our work,” he concluded.

Researchers from Faculty of Chemistry and Biology honored at Congress of European Microbiologists

Researchers from Faculty of Chemistry and Biology honored at Congress of European Microbiologists

  • Dr. Renato Chávez and biochemists Luis Figueroa and Javiera Norambuena were honored at the 5th Congress of European Microbiologists, in Leipzig (Germany) for their research on bioactive compounds from Antarctic marine sponges, which present a high microbial, antitumor and antioxidant activity.

The study’s innovation and impact and the results shown were the reasons for giving the Best Poster Presentation Award to the study conducted by a team of researchers from Universidad de Santiago and Universidad de Chile in one of the most important events worldwide in the field of Microbiology: the Federation of European Microbiological Societies Congress, FEMS 2013.

The research team is composed of Dr. Renato Chávez, researcher from the Faculty of Chemistry and Biology, Universidad de Santiago, and the biochemists Luis Figueroa and Javiera Norambuena, also from Universidad de Santiago, together with other specialists from Universidad de Chile. They conducted the study for three years.

The study is based on the analysis of new bioactive compounds, present in filamentous fungi of Antarctic marine sponges. These compounds show a high microbial, antitumor and antioxidant activity.

Discovering these new species and their properties, supported by the required laboratory research, could lead to potential applications in Biotechnology, especially in the field of Pharmacology.

Regarding the study’s development, biochemist Javiera Norambuena says that, in order to find these bioactive compounds, it was necessary to search poorly explored places, as in those places there are more possibilities of finding non-cultured organisms. “That is the reason why we isolated fungi from Antarctic marine sponges, which usually have chemical compounds containing secondary metabolites; that is to say, they are not required for the organism’s survival, but they give it advantages over other members of the population”, she adds.

Regarding the study’s results, biochemist Luis Figueroa notes, “a high percentage of the isolated fungi could not be identified, which suggested the existence of new genera in the microbial community from Antarctic marine sponges; therefore, we can conclude that the fungi community in the Antarctic marine sponges studied is completely different from the one in common marine sponges.”

“We are on the right track”

Dr. Renato Chávez, researcher and professor of Faculty of Chemistry and Biology, says, “The honor awarded confirms that our work with fungi from Antarctic sponges is of international interest.”

“The award confirms that regarding the study of Antarctic marine eukaryotes (fungi and yeasts), we are on the right track, what encourages us to continue in this line. We are aware that we are dealing with new species that have not been described yet, so describing them is among our next goals. Also, we know that these species produce chemicals with very interesting properties that could be used in the Biotechnology field. As for the students participating, this award is most certainly an incentive for them as young researchers,” Dr. Chávez adds.

The full research team that took part in the poster presentation is made up by undergraduate and graduate students from Faculty of Sciences, Universidad de Chile: Marlene Henríquez, Ivanna Araya, Andrea Beiza and Karen Vergara, while the work presented at the Congress is supported by Fondecyt Project 11090192, conducted by Dr. Inmaculada Vaca, from Universidad de Chile.

Universidad de Santiago’s professor to head the Computational Intelligence Society Chilean Chapter

Universidad de Santiago’s professor to head the Computational Intelligence Society Chilean Chapter

  • Dr. Gonzalo Acuña was elected president of the Chilean representation at the Computational Intelligence Society, which is part of the world’s largest professional and technical association in this field. Also, professor Acuña became Chile’s representative at the Latin American Computational Intelligence Society.

An academic of Universidad de Santiago’s Department of Informatics Engineering, Dr. Gonzalo Acuña Leiva, will preside for two years the Computational Intelligence Society (CIS) Chile Chapter, which is part of the Institute of Electrical and Electronics Engineers (IEEE), the world’s largest professional and technical association dedicated to advancing technological innovation and excellence for the benefit of humanity.

Dr. Acuña was elected president of the Chilean representation of the IEEE-CIS, one of the world´s most renowned and traditional organizations, as it was the first organization founded in this field after the American chapters of computational intelligence and is made up of, at least, sixty academic members from different universities.

“Computational Intelligence relates to the ability developed by computers, for example, to imitate nature or biological processes,” Dr. Acuña says, pointing out that this field includes neural networks and genetic algorithms inspired by biological processes or the animal world, like the ants’ methods to solve problems or the flight of birds.

Although the IC concept seems to be related to Informatics, Dr. Acuña says that it has to do with dynamical systems and mathematical models and not necessarily with programming.

Computational Intelligence is not Artificial Intelligence

Dr. Acuña says that the concept of Computational Intelligence should not be taken for Artificial Intelligence, as the former refers to “mathematically modeled ideas that help to solve optimization problems and other engineering works. It refers to mathematical tools that are commonly used by computer programmers to solve different problems, as they can be applied to all imaginable fields.”

Dr. Acuña has been working in this field for several years and he has specialized in the study of neural networks, interconnection systems inspired by the animal nervous system functioning and SVM (Support Vector Machines), a group of supervised learning algorithms that can be applied to different areas.

At present, the academic is leading a Fondef project where he is applying this knowledge to mining industry.

“With this Computational Intelligence tools we are building predictive models for the availability of physical assets in mining industry, like shovels, large trucks or the enormous equipment required for mining operations that involve high maintenance costs. Therefore, if we are able to anticipate the equipment availability, mining industry can improve preventive maintenance and reduce costs,” Dr. Acuña explains.

Youngsters and Latin America

About his recent nomination as president of the IEEE-CIS Chile Chapter, Dr. Acuña says that the efforts are oriented to promote the Chapter and to motivate young people through CI Summer Schools, which are “the ideal opportunity for students preparing their dissertation work to participate, as leading figures in this field give presentations and many of our members offer tutorial sessions. It is the occasion when we meet as a community.”

Finally, there is also news about this field at a regional level, as two weeks ago, in a congress held at Bariloche, the Latin American Computational Intelligence Society was founded, where Dr. Acuña and an investigator from Universidad de la Frontera were appointed national representatives.

Professors at Universidad de Santiago presented an innovative teaching approach

Professors at Universidad de Santiago presented an innovative teaching approach

  • Claudia Matus and Bárbara Ossandón, both professors at the Physics and Mathematics Teaching program of Universidad de Santiago de Chile, presented a novel initiative for the academic field at the International Educational Summit 2016: XII Conference on Higher Education Management.

 

 


Claudia Matus and Bárbara Ossandón, both professors at the Physics and Mathematics Teaching program of Universidad de Santiago, had a remarkable participation at the International Educational Summit 2016: XII Conference on Higher Education Management.

This activity has become one of the most important meetings for exchanging experiences at a management level among higher education institutions in Latin America, with the participation of renowned international experts.

The conference was held at the Casa Central of Pontificia Universidad Católica de Chile and professors Matus and Ossandón presented their work “Comunidad Práctica de Aprendizaje como elemento clave de gestión en el rediseño curricular de una carrera de pedagogía.”

“We designed a new innovative curriculum that based its pedagogical principles on a spiral modular design that involves the integration of theory and practice and is focused on the classroom activity and the student,” professor Ossandón explained.

She highlighted “the need of understanding curriculum management through an interdisciplinary team work and professional management. This means to strengthen the role of the head of the program and
distribute his/her tasks in four coordinations: practice, teaching, laboratories, and outreach and engagement. This last coordination has the purpose of providing feedback on the curriculum.”

“This interdisciplinary learning community that works collaboratively is made up of physics and mathematics teachers focused on didactics; an anthropologist, and other professionals,” she said. It is a group of committed people working in an environment where interdisciplinary collaborative work is usually understood as the sum of individual works,” she said.

“The strength of this initiative is the new design of the curriculum of the Physics and Mathematics Teaching program that allowed us to be accredited for seven years,” she added.


Conclusions

“What we want to share is the idea that, to achieve curriculum innovation, the line-up of collaborative interdisciplinary work teamsis very important in order to make the program management a profesional activity, as well as to encourage constant self-evaluation, what will result in constant improvement,” Professor Ossandón said.

The conference “helped us to validate the pedagogical principles of our program according to the different presentations given that addressed the latest trends in education that, in turn, allowed us to validate our own community, our team made up of the four coordinations. Besides, it enriched even more our pedagogical learning proposal,” she said.

“This activity is also an example of learning practice community,because on this occasion we learned about an education research network. This network is formed by universities in four continents and

it was created by the initiative of different communities, as the most advanced way of distributed leadership in the knowledge society, as Hargreaves said. This conference is a learning practice community
itself,” she added.

“We propose a professional, pro-active approach, where the head of the program can conduct research works with collaborative teams in the medium and long term,” she concluded.

Academic studies brain development process in human embryos

Academic studies brain development process in human embryos

Providing basic knowledge about human cerebral cortex development at embryonic and early fetal stage is the goal of the research project led by Dr. Lorena Sulz, which will be conducted during the next three years.

According to reports, some psychiatric disorders, such as schizophrenia and bipolar disorder, begin during embryonic development. Most of the studies on this topic have been conducted on animal samples, due to ethical restraints and limited access to human embryos. This is the reason why the field of human embryology related to neurology is an area which has not been thoroughly explored.

In this context, Dr. Lorena Sulz, academic of Universidad de Santiago’s School of Medicine, will carry out the study “Role of nitric oxide in human cerebral cortex morphogenesis”, which intends to gather critical information about the mechanisms involved in the development of nerve cells during the first weeks of pregnancy.

The study will be conducted during the next three years and is funded by the Scientific and Technological Research Department (Dicyt) of Universidad de Santiago. It is a unique study as it is the first time that this branch of embryology involves human samples, which were obtained from de Institution’s Embryo-Fetology collection.

The idea is to gather basic knowledge about this topic in order to explain if the presence of nitric oxide is also essential for producing new nerve cells in human cortex, as it has already been proved in animal samples and in neuronal regeneration processes, both in human beings and mice. “We want to know if this molecule is expressed in the cerebral cortex being developed and identify in what areas and at what stages it is present. In this way, we can infer approximately the process in which it is involved,” the academic explains.

The study will be carried out in two stages. The first one will completely focus on the morphological analysis of cells and embryos being used. This stage, which is under execution at this moment, will allow describing the human cerebral cortex development process. After identifying each phase, the second stage will allow identifying cells that produce nitric oxide and the process in which it would be involved.

The study will be conducted at the Embryology Unit of the Faculty of Medical Sciences, Universidad de Santiago, led by Dr. Jaime Pereda, the project`s co-investigator, M.S. Carlos Godoy and Dr. Sulz. The three professionals, experts in their areas of research interest, complement each other’s work in a way that has helped to a good execution of their projects. “In general, the three of us work together because we use very similar techniques: only the molecule and the body organ of interest are different. We have adjusted to each other very well,” Dr. Sulz adds.

However, the expectations are long-term. The research seeks to establish some theoretical basis for human cerebral cortex development, in order to develop new studies on this topic. The results will be presented in different papers in specialized publications and in different congresses and conferences.

Finally, Dr. Lorena Sulz expects that during the research, they will be able to prove that nitric oxide takes part in human cerebral cortex development, just like it does in laboratory animals. “As it is basic science, it only provides a knowledge base. But if nitric oxide is known to be significant in cerebral cortex development, further care should be taken so as not to interrupt this process during the critical period, preventing potential malformations. This additional knowledge could be a contribution to prenatal care,” the researcher concludes.

New innovative instrument to evaluate Early Teacher Training

New innovative instrument to evaluate Early Teacher Training

  • Professor Saúl Contreras, academic at the Department of Education, is developing the Fondecyt Project “Early Teacher Training for Science Education” that seeks to analyze the academic performance of 1,200 Teaching Training Program students across the country to contribute with an explanatory model on how future teachers internalize and implement their curricular teaching knowledge.
  • According to professor Contreras, this instrument will put a strain on the Inicia Test,” because the latter evaluates future teachers at the end of their training. “Our idea is to evaluate students during all their training process,” to obtain a comprehensive and timely knowledge about it.
  • Professor Contreras presented the first results of this study at international conferences in Tarragona and Barcelona, Spain.

The quality of education is today a core topic in the public policies debate and it has become one of the key demands of different social sectors.

But this quality is affected by different variables, like the good or poor education received by those who will be responsible for teaching new generations, that is to say, Early Teaching Training, (FDI, in Spanish). This is why Dr. Saúl Contreras, PhD in Education of Universidad de Santiago de Chile is working on the project “Early Teaching Training for Science Education”, funded by Fondecyt, that seeks to create a model and an instrument to evaluate the training process of pre-service teachers. As a result, this would allow training institutions to review the decision making process regarding training matters.

The study considers a national sample of 1,200 trainee teachers in math and experimental science specializations. The research team led by Dr. Contreras will do the corresponding follow up for four years.

“We seek to create a model and an instrument to explain how students acquire teaching competences and skills. In the context of the study, we are going to provide important data to each participating institution,” Dr. Contreras says. He adds that this information will be very useful to correct the course of early teacher training.

“It will put a strain on the INICIA Test”

Professor Contreras claims that among the side effects of this study, “it will put a strain on the Inicia Test,” the voluntary test to evaluate graduate teachers in different contents. “It does not make any sense to expect a quality education by thinking that we can achieve it just through measuring instruments like Simce, PSU or the Inicia Test.”

Professor Contreras also stresses that the Inicia Test evaluates pre-service teachers at the end of their training programs. “We propose to have a systematic assessment instrument during the whole training process and not only at the end of it. Because we should ask ourselves if the results of the Inicia Test are not good and the students already graduated, what happen to them? Should we give them remedial courses? It is too late to do it”, he answers.

For all the above, the instrument studied by this researcher at Universidad de Santiago de Chile becomes essential, because, according to Professor Contreras, it is not about preparing students like pre-university schools do: it is “creating and applying an instrument to evaluate future teachers at certain time points during their training. And this is a decision of the institutions that internally choose to help their students.”

Regarding the assessment tests, Dr. Contreras says that he totally agrees with their application, “otherwise it would be impossible to know how we are doing,” but these instruments should be developed “together with the subjects and starting with them, because they also need to be relevant,” he explains.

Professor Contreras is so convinced of the effectiveness of his proposal that he does not doubt that, after applying the assessment instrument for four years, it may be applied at a national level, in the context of a public policy. He thinks that it “can also be implemented in the technical- professional formation.”

Although the first stage of collection of data was finished only a few weeks ago- with the collaboration of teacher training programs of universities from Arica to Punta Arenas- professor Contreras presented the first results of this project at the International Congress of University Teaching and Innovation (CIDIU, in Spanish), held at Tarragona, Spain and then, at the Edulearn VI International Conference on Education and New Learning Technologies, in Barcelona, Spain.

These first steps allow seeing significant changes in future teachers’ training that, in the end, will affect the quality of education.

Professor at the Department of Physics inquiries into the composition of the universe’s dark matter

Professor at the Department of Physics inquiries into the composition of the universe’s dark matter

  • Dr Paola Arias, together with her research team, will search for signals of new particles in cosmological observations and lab experiments, in the context of a Fondecyt Regular project 2016. Currently, there are independent efforts worldwide oriented to this search; the team’s goal is to propose new and better detection techniques.

 

 

The search for new particles has been in the general interest for a long time. The most popular example in this field of study is the Large Hadron Collider (LHC), the world’s largest particle collider that allows studying the elements which are part of the matter that forms the Universe. However, the mysteries hidden in the vastness of the Cosmos are countless, like the ones in the “dark sector”, which is formed by particles that cannot be easily observed, because they do not interact with our detectors; we only see their gravitational effects, as in the case of dark matter.

“Our project will look for particles different from the ones than one may expect to find in the LHC, as they would distinctively have a very little mass. Currently, there are independent efforts worldwide oriented to this search, but our goal is to propose new and better detection techniques,” Dr Arias explains. The research team in charge of this Fondecyt Regular project (1161150) “Looking for signatures of a hidden sector” is made up of scientists from Argentina, Germany, Spain and Switzerland.

According to professor Arias, their work is based on observational evidence in this field of study that suggests that the Universe has a higher content of particles if compared to what we see now. She explains that this information has led to the formulation of different theoretical models on the properties of these new particles and predictions about how we could watch them.

“Technological progress has been possible thanks to the knowledge and understanding of the world around us,” she adds. “Particle Physics is a basic science and its purpose is to understand the Universe where we live in. For now, we cannot measure how this will contribute to society. As we still have not learned about the intrinsic nature of these new particles, we do not know how they can be a contribution in the future. Undoubtedly, understanding the Universe is a question that has fascinated mankind since its origins.” 

For Dr Arias, being part of the Department Of Physics at Universidad de Santiago de Chile has been a great experience. "The level of the research work at the university is very high and we expect to continue strengthening it,” she concludes.
