Welcome.
I study how climate change reshapes extreme weather, with a focus on tropical cyclones and tornadoes, and why climate models often disagree with observations about it. A central thread of my work is the role of sea surface temperature warming patterns: how model biases, such as the double-ITCZ bias, distort simulated responses to forcings like aerosol reductions and Antarctic ozone depletion, and how flux adjustment can correct them. I also build physics-informed deep learning tools for tropical cyclone monitoring, including a real-time product and a 37-year tropical cyclone size dataset that are openly available.
