Research Interest:

My research centers around hydro-climatology with a focus on extreme weather events and land-atmosphere interactions. Currently, I am working on developing and utilizing physics-based box models of the Earth system that explicitly consider thermodynamic limits as a constraint on surface-atmosphere exchange. These models then enable me to investigate various aspects of temperature variability, turbulent exchange and hydrologic sensitivities. By integrating observations, data analysis, and modeling approaches, I seek to contribute to the advancement of our understanding of the Earth system and its response to climate change.
