Fangni Lei

Visiting Assistant Professor of Engineering

Overview

My research focuses on enhancing the quantification of global hydrological parameters and advancing the understanding of land-atmosphere interactions by integrating remote sensing big data, physical models, statistical methods, and artificial intelligence techniques. My work encompasses a range of topics, including soil moisture quantification from microwave remote sensing, land surface water-energy balance modeling, watershed-scale hydrologic modeling, hydrologic data assimilation, flood mapping, and agricultural water management. I am currently an assistant research professor at the Eversource Energy Center and the Department of Civil and Environmental Engineering at the University of Connecticut. I earned my BS, MS, and PhD degrees from Wuhan University and was a visiting student at the Hydrology and Remote Sensing Laboratory of the USDA Agricultural Research Service. Following my PhD, I continued my research as a post-doctoral associate at USDA and then as a research assistant professor at Mississippi State University.
