I am currently a postdoctoral scientist at NASA Jet Propulsion Laboratory. My research centers on better understanding how weather systems interact with geographical features to produce climate extremes (especially heat and precipitation) at local and regional scales. Sequences and combinations of variables which result in 'compounded' or 'correlated' societal risks figure prominently in my work. My projects tend to employ a variety of approaches, ranging from analysis of observational data to validation of global climate models and custom runs of regional climate models. My interests also include producing and communicating climate information such that it is maximally useful for decision-making, through contributions to impacts assessments, policies, and educational and outreach activities.

Interdisciplinary Activities
-Co-lead of the Risk KAN Compound Events working group (~250 members); have been organizing regular webinars and other networking activities since April 2020.
-Primary organizer of the "Workshop on Correlated Extremes", a ~175-person event held at Columbia University in May 2019. Our goal was to weave together multiple physical- and social-science perspectives on correlated climate extremes -- an emerging topic spanning meteorology, climatology, natural hazards, and policy/finance -- and to help build research networks and shape research directions in this area. More information is available at our website. Recordings of all talks are available on Youtube.
-Conference organization and chairing:
Workshop on Compound Weather and Climate Events, January 2021
"Correlated climate extremes" sessions at AGU 2021, 2020, and 2019
"Extreme heat events: processes, impacts, and adaptation" session at EGU 2019
