Tarsilo Girona Hernandez

Társilo Girona received undergraduate training from the University of Valencia and the Complutense University of Madrid, the latter being from where he received a Bachelor's Degree in Physics (2009) and a Master's Degree in Geophysics and Meteorology (2010). During his undergraduate studies, he pursued an internship at the Institute of Earth Sciences Jaume Almera, Barcelona, where he started his career in Physical Volcanology. In 2010, Társilo received a Singapore International Graduate Award to carry out his Ph.D. at Nanyang Technological University, Singapore; his doctoral research focused on unraveling the dynamics of frequently erupting volcanoes through new theoretical, computational, and experimental models. Between February 2015 and August 2017, Társilo worked as a Postdoctoral Research Fellow at the Earth Observatory of Singapore, Georgia Institute of Technology, and Brown University. Since August 2017, he works as a NASA Postdoctoral Fellow at Jet Propulsion Laboratory. Társilo's long-term goal is to improve the prediction of volcanic eruptions and earthquakes by combining process-based models, statistical tools, and satellite-based data.
