The complex topography and highly varying weather of my native Upstate New York led to my enduring interests in understanding how meteorology and geography interact to shape climate, and especially extremes. As a JPL postdoc, I am focusing on ways to better predict hydrological phenomena characteristic of the West Coast (such as atmospheric rivers and multi-year droughts), and to combine this knowledge with my prior work on heat waves to produce an improved process understanding of heat stress regionally, nationally, and globally.
