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.

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.
