I am an Assistant Professor at the Courant Institute of Mathematical Sciences, New York University. I am affiliated with the Center for Atmosphere Ocean Science within Courant. I was a Miller Postdoctoral Fellow at the University of California, Berkeley from 2021 to 2023, hosted by William Boos. I earned my PhD from Princeton University in 2021, advised by Stephan Fueglistaler.

Full of uncertainty and disorder, the Earth’s climate system is a unique subject in complex systems science. Reducing complex phenomena to simple laws is fascinating to me as a scientist.

Climate science also serves a more practical mission – to better prepare societies worldwide for the impact of climate change. Accurately predicting future changes in climate and extreme weather requires a fundamental understanding of underlying physical mechanisms. I am interested in atmospheric dynamics and the interaction between dynamics, thermodynamics, and radiative transfer.

I particularly appreciate the insights that analytical theories provide, whether they are predictive or diagnostic. Achieving quantitative agreement with simple theories can be challenging in our complex climate system, but I strive to incorporate analytical components in each piece of my research.

Mar 7, 2025 Our model in Zhang et al. (2024) successfully predicted the record-breaking 2024 tropical extreme wet-bulb temperatures, as detailed in Forecast.
Dec 9, 2024 A new paper led by Heng Quan, third-year graduate student of Princeton University, is published in Journal of Atmospheric Sciences. In this paper, Heng made a convincing case for weaker horizontal temperature gradients in a warmer climate, extending our fundamental understanding for tropical atmospheric dynamics that is based on the weak-temperature-gradient approximation.
Nov 5, 2024 A new perspective piece led by Dr. Mike Byrne from the University of St Andrews, discussing the use of theory and idealized modeling to advance land-climate science, has been published. Read the article here.
Apr 14, 2024 Our paper, detailing a physics-based statistical model for the annual maximum wet-bulb temperature (TWmax) in the tropics, is out. See TWmax predictions for 2024 based on the methodology under the “forecast” tab.
Mar 14, 2023 My paper with Bill Boos on midlatitude extreme temperatures is published in PNAS. We proposed a theory for an upper bound of surface air temperatures. Read here.
