POST DOCTORAL RESEARCH ASSOCIATE

Biography

Dr. Tiansong Qi joined Ä¢¹½ÊÓƵ in December 2025 after earning his Ph.D. in civil engineering with an option in water resources from North Dakota State University. He received his bachelor's degree in hydrology and water resources engineering from Hohai University, China, in 2016. His research interests include hydrology and water resources, watershed modeling, drainage water management, wetland hydrology, managed aquifer recharge and karst hydrology.

Currently, he works in the HydroSolve Lab under the supervision of Sushant Mehan. His current research focuses on modeling and evaluating advanced tile drainage practices to improve crop productivity and agricultural water management.
