Welcome

I am an Assistant Professor in McGill University's Department of Atmospheric & Oceanic Sciences.  My research group uses a combination of passive and active remote sensing observations, and models as tools to better understand the role of clouds in Earth’s changing climate.  Clouds remain the largest source of uncertainty in climate projections.  In particular, the response of clouds to global warming, referred to as cloud feedback, remains the primary cause for the intermodel spread in the equilibrium climate sensitivity --- a metric that quantifies the ultimate change in global mean surface temperature in response to a doubling of atmospheric carbon dioxide. 

The focus of our research is on mixed-phase clouds, that are composed of both supercooled liquid droplets and ice crystals.  Compared to their warm-cloud counterpart, precious little is known about their relatively complex micro-scale physical processes.  As observations of mixed-phase clouds continue to improve in quality and scope, research on the role of these clouds in a changing climate will continue to be a growing and exciting field for decades to come as we strive for more reliable projections of global climate change.
