Andres F. Gualdrón-Reyes is an auxiliary professor at Universidad Austral de Chile. He was a postdoctoral student at the Institute of Advanced Materials (INAM) at Universitat Jaume I, Spain. He obtained his PhD in Chemistry at the Universidad Industrial de Santander, Colombia, in 2018. During his PhD studies, he joined to INAM for six months under supervision of Prof. Iván Mora-Seró, focusing on the synthesis of mixed halide perovskites for light-emitting diodes free from phase segregation. Currently, he is working on the synthesis and photophysical characterization of nanocrystals (chalcogenides and perovskites), with applications in photo(electro)catalysis, optoelectronics, and photovoltaics.
