Weiyi Tang

Weiyi Tang is an Assistant Professor at the University of South Florida College of Marine Science, specializing in biogeochemistry and climate change. His research integrates laboratory experiments, field observations, isotopic methods, remote sensing, machine learning, and numerical modeling to investigate ocean ecosystem responses to human activities and climate feedbacks.

Research interests focus on:

• Global nitrogen cycle processes (N₂ fixation, nitrification, denitrification, N₂O cycling)
• Marine carbon cycling and biological productivity
• Global biogeochemical data compilation and meta-analysis
• Development of biogeochemical observation methods and instruments

His work combines nitrogen isotope analysis, microbial characterization, and statistical tools to understand environmental drivers of biogeochemical cycles.

Recent publications (2022-2025) reveal strong emphasis on nitrogen transformation kinetics in estuarine and oceanic systems, particularly nitrous oxide dynamics under varying oxygen conditions. Key trends include machine learning applications for global nitrogen fixation modeling, dust-driven phytoplankton blooms, and anthropogenic impacts on greenhouse gas emissions. Studies frequently leverage high-resolution field data from the Chesapeake Bay and North Atlantic.

Dr. Tang actively recruits undergraduate, graduate, and postdoctoral researchers for his Biogeochemistry Lab, with current openings for candidates specializing in geochemistry, microbial biology, or satellite remote sensing. His group collaborates on diverse biogeochemical processes using interdisciplinary approaches.

The Biogeochemistry Lab develops innovative methodologies including cavity ring-down laser absorption for underway N₂ fixation measurements and molecular techniques for characterizing nitrogen-cycling microbes. Current projects examine climate change impacts on nitrogen-carbon-climate interactions in marine ecosystems worldwide.
