Pablo Andrés Fuentealba Castro completed his graduate studies at the Universidad de Chile, receiving the diploma for the academic degree of Doctor in Chemistry. Part of his thesis was done at the Université de Rennes 1, Rennes, France, and part also at the Instituto de Fisica-Universidade de Sao Paulo, Sao Carlos, Brazil. In 2016, he was hired as part of the professional team of the Universidad de Chile, where he started to teach undergraduate students. That same year he also made a postdoctoral research stay at the “Centro para el Desarrollo de la Nanociencia y la Nanotecnología” (CEDENNA), and in 2017 he began his postdoctoral project at Universidad de Chile. His expertise is based on the synthesis of novel inorganic compounds based on 3d and/or 4f cations, through different synthetic pathways, and the characterization in solid state of different materials through single crystal and powder X-ray diffraction, combined with spectroscopic techniques. He has worked in the analysis of magnetic and optical properties of transition and lanthanides cations. In 2019, he was recognized as “one of the best oral communications” at a Latin American Conference (SILQCOM), and he was named as “Honour Leading Scientist”, receiving an Honour Diploma at a European Conference, 26th Advanced Materials Congress, held in Stockholm, Sweden. In 2020, he has been honored with “IAAM Young Scientist Award”. Nowadays, he is an Assistant Professor at Universidad de Chile. Teaching and guiding undergraduate and graduate students. He is a part of the Graduate Committee of the Facultad de Ciencias Químicas y Farmacéuticas, Universidad de Chile, and in research and mainly focused on the optical properties of lanthanide-based materials.
