I am Zhengxiao Yan (could be pronounced like John-Shawn Yan๐), received Ph.D. at Florida State Universityโs FAMU-FSU College of Engineering, specializing in Civil Engineering, working with Dr. Nasrin Alamdari. My academic journey began with a B.S. in Environmental Science from Hohai University, an M.E. in Environmental Engineering from Northwest University under the supervision of Dr. Jun Xia and Dr. Jinxi Song, and an exchange program in Civil Engineering at the University of New Mexico, where I spent part of my time working with Dr. Ricardo Gonzalez-Pinzon. My passion for environmental science and engineering has driven me to explore various aspects of geosciences.
My research interests lie at the intersection of machine learning, climate change, ecological modeling, carbon flux, storage, and sequestration, environmental health, hydrology and geographical modeling, remote sensing, and water & food resources and security. I am currently focused on modeling terrestrial ecosystem carbon fluxes between land and the atmosphere and carbon storage in the agricultural landscape in the USA, working with Dr. Conghe Song at University of North Carolina at Chapel Hill. Generally, my work often involves using advanced algorithms/modeling and multi-source data to develop process-based or ML-based models for environmental decision-making and policy development. I have published several papers in the top journals in my research fields
