Enjoying numerical methods and high performance computing

Her name is Maria Guadalupe Barrios Sazo, but she goes by Lupe. She has come all the way from Guatemala to work as a Research Software Engineer at RoCS - Rosseland Centre for Solar Physics.

She arrived from New York in September where she finished her Ph.d.-degree this summer.

My PhD work and the work I will be doing here overlaps in some of the numerical methods used and computational techniques to make codes sustainable and efficient, 

explains Lupe.


Lupe is originally from Guatemala and she did her BSc in Physics at Universidad del Valle de Guatemala (University of the Valley of Guatemala) before she entered a direct PhD program in Physics at Stony Brook University in New York. 

- My research as a graduate student was in Astrophysics, specifically in the simulation of White Dwarf Mergers and MHD studies. The collaboration around the code used, Castro, allowed for this project to execute on Summit, a GPU super computer at OLCF. While doing my research I enjoyed and developed special interest in numerical methods and high performance computing, says Lupe.

- What will your work field be?

- I will be contributing to the efforts in enhancing the codes used by the center, especially Bifrost, to run in the state of the art super computers. This can be done by supporting the community development through productivity tools, expanding verification of the code and further study the code portability with the DISPATCH framework.  

Drawn to Norway

- What brought you to Oslo and RoCS?

 - The position for Research Software Engineer at RoCS described aspects that I have enjoyed in the past and I am excited to continue learning and sharing my experiences in an academic environment.

The broad research of the Sun at RoCS provides a niche of continuous development and learning in astrophysics, computation and numerics.  Noticing that the group is involved in community engagement and outreach activities was very attractive too.

One of the ways that Norway appealed to me was in the interest of the society towards protecting the environment and immersing itself in nature.   

- How can you describe your experience so far and what do you expect for the future?

- I have encountered a friendly and helpful community at ITA. It is nice to explore new places and meet new people. I look forward to growing professionally and socially with my new colleagues at this prestigious institute. I am excited to explore Oslo and the rest of Norway; one of my dreams is to experience the northern lights.
