Last update: May 10, 2021

I am a physics-based modeler and data scientist. I received undergraduate training from the University of Valencia and the Complutense University of Madrid; the latter being from where I received a Bachelor's Degree in Physics (2009) and a Master's Degree in Geophysics and Meteorology (2010). In 2010, I received a Singapore International Graduate Award to pursue my PhD at Nanyang Technological University, Singapore. My doctoral research, focused on unraveling the dynamics of volcanoes through new data analysis and physics-based modeling, was awarded the Natural Hazards Award for Graduate Research 2016, given annually by the American Geophysical Union to "outstanding contributions to natural hazards research by a young scientist". In December 2018, I received a Certificate in Data Science from the University of California, Los Angeles. Between February 2015 and August 2017, I worked as a Postdoctoral Research Fellow at the Earth Observatory of Singapore, Georgia Institute of Technology, and Brown University. Between August 2017 and June 2020, I worked as a NASA Postdoctoral Fellow at Jet Propulsion Laboratory, California Institute of Technology. My work at NASA, which integrated terabytes of remote sensing data, machine learning techniques, and process-based models, was awarded a 2019 JPL Outstanding Postdoctoral Research Award. Since September 2020, I have been working as a Research Assistant Professor at the University of Alaska Fairbanks - Geophysical Institute, and I have been a member of the Alaska Volcano Observatory.
