Graduate student Greg Petersen continued his PhD research at the National Atomic Energy Commission in Buenos Aires this summer as part of the Spin-Polarized Partnership for International Research and Education (SPIRE).

During his stay in Buenos Aires, Petersen learned a new research technique that he will incorporate into his work with Dr. Sandler—parameterized tight binding.

Petersen says explaining his research to the directors at the National Atomic Energy Commission was challenging but rewarding.

“When I went there, I had to defend how I saw the research problem,” he said. “The directors would ask me questions that would help me find holes in my understanding.”

When not researching, Petersen explored Buenos Aires and other parts of Argentina. For more on his trip, read his SPIRE blog.
