From March 26^th to April 1^st, our group member Andrés Borloz-Chinchilla and me, participated in the II Summer School Theory on NMR, in Windischleuba (Altenburg, Germany). The summer school was organized by Prof. Jörg Matysik (Universität Leipzig, Germany), with the support of the International Society of Magnetic Resonance (ISMAR). More than 45 attendees participated in the event, between PhD students, postdocs and professors, coming from more than 10 different countries. Mr. Borloz-Chinchilla and I were the only representatives from the Latin American region.

The main topic of the school was Relaxation, where we learned about quantum mechanic operators in NMR, Hilbert space, density operators, tensor products, Liouville space and super operators, and Redfield theory. During the school we had the opportunity to interact with professors like Matthias Ernst (ETH, Zürich), Amir Goldbourt (Tel Aviv University, Israel), and Christian Bengs (University of Southampton, UK), but also with many amazing PhD students and postdocs working in the NMR field. It was a great experience for connecting with colleagues and broaden our international network.

Finally, I would like to acknowledge Prof. Matysik for his amazing organization and support before and during the event, and to Vicerrectoría de Vida Estudiantil y Servicios Académicos (VIESA) at Tecnológico de Costa Rica for the travel scholarship to Mr. Borloz-Chinchilla.
