Last week, we conducted a two-day seminar and hands-on session at the Physics Department of the University of Seville for Erasmus Mundus students. We began by introducing our activities and then explored topics ranging from environmental radiation detection to Nuclear Imaging. The interaction with such motivated students was incredibly rewarding. I’m grateful to Professor Marcos Aurelio Gonzalez Alvarez and the Master’s program coordinator, José Antonio Lay Varela, for the invitation. Special thanks to Juan Pablo Fernandez Garcia and Lucas Garrido Gomez for their support. Eagerly anticipating next year’s session and welcoming you all to our summer school.
