My research interests lie in atmospheric sciences and land/ocean-atmosphere interactions at a range of spatial scales (regional to local) that are relevant to the management of human and natural systems. My research focuses on reducing vulnerabilities and increasing readiness in urban, agricultural, and natural environments in a changing climate. I perform targeted dynamical downscaling experiments with the overarching goal of creating “bridges” between global, regional and micro-scale modeling. Another dimension of my research is to work at the intersection of science, engineering, and social sciences to perform collaborative and translational research that benefits society. I am a fellow of the Royal Meteorological Society and an executive committee member of the Center for Urban Resiliency and Environmental Sustainability (CURES) across the University of Illinois system. I collaborate with cities and institutions to work on environmental issues related to heat, fog, air quality, and high-impact weather.
