Visiting Humboldt Fellow Prof. Óscar Herrera-Sancho has been working with Professor Tilman Pfau, Head of the University of Stuttgart's 5th Institute of Physics since November 2022. His initial study visit phase is due to end in April 2023 and will be followed by two more during the following two years, each of which will also last from November to April – as we know, not the best time of year to visit Germany. But this Costa Rican actually likes the cold, and low temperatures also play a major role in his research.
