Tracking the impact of the CODATA/RDA data science schools: the case of the OSG

The CODATA-RDA Research Data Science Schools provide Early Career Researchers with the opportunity to meet their colleagues and learn relevant Data Science skills. We actively encourage students to use their learning as an opportunity to create new collaborations and generate new research.

One spectacularly successful example of this is Oscar Arbelaez Echeverry from Colombia who, through links made at the schools, enabled approximately 1.2 million CPU hours [this is akin to having access to a 1600 core cluster for a month] to be run on Monte Carlo simulations. As a result of accessing the Open Science Grid resource, six publications [1-7] have been generated by his supervisor, in the best journals in the field and for wider audiences . By providing Oscar with the relevant skills, he has been instrumental to advancing research in his home institution.

Oscar attended the Trieste school in 2017 (#dataTrieste17). He has a background in Condensed Matter Physics and was working with Juan Alzate-Cardona at the Departamento de Física y Química, Universidad Nacional de Colombia, Manizales. Juan is working on computational studies of magnetic materials. This requires extensive Monte Carlo simulations of the materials and is highly computationally intensive, but allows insights into the nature of the materials such as the magnetocaloric effect - which in essence is how the temperature of a magenetic material changes when subjected to a change in the magnetic field around it.

As it was, the research team was highly limited in the work they could do because they didn’t have sufficient access to compute resource and were unaware of freely accessible services like the Open Science Grid (OSG) and how to apply them. During the school Oscar was introduced to the OSG in the Computational Infrastructures course run by Rob Quick. OSG scavenges computing cycles from  from the vast amount of grid computing clusters available worldwide and offers 1.5 billion CPU hours per year which is free and open to all researchers. Oscar described the problem he was having to Rob and they agreed to make use of the OSG.

Since being a student at the school in 2017, Oscar has gone to act as a helper in the school in São Paulo, Brazil. He is now in Switzerland completing research for his PhD. This success story is precisely why we work on these schools - the schools are not just about the materials; they are about building communities and creating connections. These connections are key in enabling these opportunities and successes for researchers in Low and Middle Income Countries.

If you give people access to tools and teach them how to use them, you can transform the research being generated. The CODATA/RDA schools are doing this across the LMIC, one student at a time. Well, 250+ now and counting… Just imagine the ripple effect all these individuals have had in their home communities!
