Research: Biogeochemistry and Climate Change

Specialties: Nitrogen Isotopes, Nitrogen and Carbon Cycling, Marine Productivity, Greenhouse Gases, Machine Learning

I am an assistant professor at USF College of Marine Science. Our research group investigates the nitrogen-carbon-climate interaction, especially the response of the biogeochemical cycling of nitrogen and carbon to human activities, and their potential feedback to changes in climate. Our approach to study nitrogen and carbon cycling is interdisciplinary, including laboratory experiments and field observations with various isotopic and molecular methods, remote sensing, machine learning and numerical modeling. For example, recent work includes the use of nitrogen stable isotopes to measure the rates of different nitrogen transformation processes and the use of gene sequencing to characterize the microbes involved in the nitrogen cycle in the Chesapeake Bay and North Atlantic. We apply statistical tools to improve the understanding of environmental drivers on biogeochemical cycling and develop mechanistic models to predict the global distributions of biogeochemical processes in the modern and future climate.  

Our current research areas are: 1) Global nitrogen cycle (N₂ fixation, nitrification, denitrification, N₂O cycling, etc); 2) Marine carbon cycle and biological productivity; 3) Global biogeochemical data compilation and meta-analysis. Please visit Biogeochemistry lab web page for more information. We are interested in collaboration in a wide range of biogeochemical processes and are seeking motivated scientists to join our group! Please contact Weiyi Tang for more information and for queries about undergraduate, graduate, and postdoctoral research opportunities. 

I am recruiting graduate students who will start in fall 2025. Please see Prospective student webpage for information about the application.
