Marysa Laguë is a climate scientist with a PhD in Atmospheric Sciences and MSc degrees in both Atmospheric Sciences and Applied Mathematics from the University of Washington. Her research focuses on understanding how terrestrial processes impact the atmosphere and surface climate from the scale of a single plant to the scale of a planet, by modulating fluxes of water and energy between the land and the atmosphere.

Marysa’s current research can be loosely separated into three segments: understanding connections between the land and the atmosphere in the modern climate, understanding the basic physical connections between terrestrial and planetary processes using idealized models and theory, and climate model development. For example, she studies how changes in vegetation impact cloud formation, temperatures, water vapor, and atmospheric circulation in ways that can feed back on surface climate both locally and remotely. On the idealized side, she studies how changes in the distribution of continents over planetary surfaces fundamentally alters global-scale climate. She uses and develops numerical models of varied complexity to quantify the role of land in the coupled Earth System.
