About


Research

I am a postdoctoral scientist in the Advanced Study Program at the National Center for Atmospheric Research. I study decadal-to-centennial timescale climate dynamics with a focus on hydroclimate over North America during the Common Era. Specifically, my work combines state-of-the-art coupled General Circulation Models with observed and paleoclimatic data to better understand climate dynamics on timescales that cannot be sufficiently understood using instrumental data alone. This includes features that have long timescales of variability (e.g. megadroughts) or that are rare (e.g. pan-continental droughts), as well as interannual dynamical relationships that, while potentially well characterized by observations, are non-stationary (e.g. winter-to-summer precipitation phasing in Southwestern North America and the tropical Pacific-to-North America teleconnection).
