Dr. Qiang(Ted) Li is an Assistant Professor at University of Houston-Downtown. He uses multidisciplinary approaches (including field and laboratory techniques) to investigate source, transport, and fate of nutrients across plant-soil-water continuum and strives to incorporate models to better predict nutrients dynamics in the context of climate change. His previous research includes developing best management practices (BMPs) to improve soil health and nutrient use efficiency on farm scale, examining how BMPs affect nutrients transport in the edge-of-field runoff, and investigating phosphorus sources and bioavailability in various watersheds using multi-isotopic tracers. He worked as a Research Associate at University of Wisconsin-Madison from 2020 to 2023. Prior to his appointment at UW-Madison, Ted received his Ph.D. in Soil Science from University of Delaware in 2020, master's degree in Soil Science from Chinese Academy of Sciences in 2015, and bachelor's degree in Agricultural Resources and Environment from Southwest University in 2012.
