About Me

I'm an NSF postdoctoral fellow in the Program in Atmospheres, Oceans, and Climate in the Department of Earth, Atmospheric, and Planetary Science at the Massachusetts Institute of Technology. I work with Paul O'Gorman on large-scale climate and atmospheric dynamics.

My research is motivated by my desire to quantify and reduce the uncertainty of the effects of human-induced changes on large-scale atmospheric phenomena like monsoons and storm tracks. Using a combination of observations, theory, and climate models of varying complexity, I explore the fundamental physical processes that are altering the annual cycle, the hydrological cycle, and sea ice-atmosphere interaction. I am also interested in better understanding natural climate variability, especially for how it can be used to constrain climate sensitivity.

My current work is focused on modifying our theories of mid-latitude atmospheric dynamics to include the effects of moisture. I'm also researching the effects of sea ice loss on the extratropical atmospheric circulation and how extreme weather events might change in response.

For my PhD I studied projected changes to the annual cycle of temperature and precipitation due to increasing greenhouse gases in the Department of Applied Physics and Applied Mathematics at Columbia University with my advisors, Michela Biasutti and Adam Sobel.
