I am a Ph.D. Candidate at the Department of the Geophysical Sciences of the University of Chicago. My research aims at improving our understanding of mid-latitude atmospheric waves and high-impact extreme weather and climate events.

Sub-seasonal to seasonal variability poses a forecast gap between medium-range and seasonal timescales. High-impact extreme events such as heat waves, cold spells, and heavy precipitation episodes often occur on this key timescale, and are challenging to predict.

My thesis research is focused on the periodic behavior in the mid-latitude storm tracks – a newly identified climatic driver of extremes. To that end, I adopt a novel wave activity theoretical framework to diagnose key features. I use a hierarchy of GCMs, aided with a two-layer quasigeostrophic model (the E. Coli of climate models, Held 2005), to investigate physical mechanisms.
