Tianyi Sun

Postdoc Climate Science Fellow


Areas of expertise:
Climate variability and change, climate modeling, ocean-atmosphere interactions, El Niño-Southern Oscillation

Tianyi’s research focuses on the impacts of short-lived climate pollutants. She explores how methane emissions and their mitigation affect ocean warming and sea level rise. She also supports the climate science communication efforts at EDF.


Tianyi recently graduated from University of Texas at Austin with a Ph.D. in Climate Dynamics. At UT, she studied the origin of decadal climate variability and how it interacts with the El Niño and La Niña phenomena. She has presented her work at many international conferences and won the “outstanding oral presentation award” at the American Meteorology Society annual meeting twice in 2018 and 2019.
