My work focuses on separating the physics that are fundamental to extreme events from the conditions imposed by a variety of climates. My prior research focused on applying tropical meteorology theory to giant planet dynamics. I am now increasingly interested in terrestrial problems. My current research concerns the outflow dynamics of the worst storms on Earth: tropical cyclones and supercells. 

I received my B.S. in Physics at the University of New Hampshire in 2009 and my Ph.D. in Atmospheric Sciences at MIT in 2015 working with Dr. Kerry Emanuel. I was a Koshland Prize Postdoctoral Fellow at the Weizmann Institute of Science and then a T. C. Chamberlin Fellow at the University of Chicago before joining the Earth System Science faculty at Stanford in 2018. I am also currently a Center Fellow, by courtesy, of the Stanford Woods Institute for the Environment.

I work on understanding the rapid structural and intensity changes in hurricanes from an energetics perspective. Specifically, my focus is on investigating the non-stationary relative geography of the energy sources and sinks within a hurricane vortex, and in understanding how local energy transactions may lead to a vortex (system)-scale impact. Prior to joining Stanford, I obtained a Ph.D. in Atmospheric Science from Purdue University and a Masters in Fluid Mechanics from Imperial College London.




Ipshita Dey

PhD student

I completed my Bachelor’s degree in Physical Sciences from Indian Institute of Space Science and Technology, India in 2013. I worked as a scientist in the Atmospheric Sciences Department in Space Applications Centre, ISRO for 5 years before moving to the US to pursue my doctoral degree. I am broadly interested in understanding dynamics of tropical weather systems such as hurricanes and monsoons and their impact on climate variability. To achieve this, I hope to make synergistic use of ground and space-based observations along with idealized and non-idealized numerical models.




Hao Fu

PhD student

I am interested in the fluid dynamics of atmosphere ranging from raindrop scale to the general circulation, especially for the tropical region where moisture plays an important role. Currently, I am studying convective cold pool formation and its role in triggering new convection. Before I came to Stanford, I used to study the vortex dynamics of rotating Rayleigh-Bénard convection in lab, as well as a semi-analytical theory of how much rain can a cumulus cloud produce.
