I am a climate dynamicist with a passion for understanding the role of the ocean and its interactions with other Earth systems in a changing climate. My work focuses on quantifying and understanding large-scale climate variability and predictability, with particular interests in interactions between ocean and atmosphere fluctuations. I have received my Ph.D. degree in Earth and Atmospheric Sciences at Georgia Institute of Technology under the advisement of Prof. Emanuele Di Lorenzo.

I am currently an associate research scholar working with Dr. Tom Delworth at Cooperative Institute for Modeling the Earth System (CIMES), a research collaboration between the Atmospheric and Oceanic Sciences (AOS) Program at Princeton University and the Geophysical Fluid Dynamics Laboratory (GFDL) of the National Oceanic and Atmospheric Administration (NOAA).
