Research
My work uses observations, climate-model ensembles, statistical
methods, and regional downscaling to understand climate variability
and improve projections of regional change. I am especially
interested in heat, hydroclimate, emergent constraints, and the
separation of forced change from internal variability.
I work in the
Climate, Pollution, and Solutions group,
using the
Western US Dynamically Downscaled Dataset (WUS-D3)
with PyPSA to explore how climate
and weather data can inform power-grid and renewable-energy simulations.
Projects
A site for Madera County residents to use to learn about
resources for addressing dry wells or emergency water needs.
It also contains a dashboard to view recent trends in
drought, groundwater storage, snowpack, rainfall, and
temperatures against historical records.
