I received my Ph.D. from Duke University in 2019 working with Prof. Nicolas Cassar. I then worked as a postdoctoral fellow in the lab of Prof. Bess Ward at Princeton University. I am interested in understanding the biogeochemical cycles of nitrogen, carbon and many other elements, and their connection to Earth’s climate system.
I am 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 received a B.S from Eckerd College in 2025 in Marine Science and Mathematics, with a minor in Chemistry. During my time in undergrad, I completed a senior thesis working with stone crab physiology and stochastic modeling with Dr. Philip Gravinese. I am interested in being a cross-disciplinary marine scientist, applying both laboratory techniques and mathematical modeling to predict changes under future climate scenarios. I am excited to pursue a M.S. With Dr. Weiyi Tang starting in the fall of 2025.

I graduated from the ²ÝÝ®ÊÓÆµ in 2022 with my bachelor's degree in biology. After this, I worked at Mote Marine Laboratory in Sarasota, FL in Dr. Emily Hall's Chemical & Physical Ecology and Ocean Acidification departments. During my time there, I gained extensive lab and field work experience and ran analyses including dissolved inorganic carbon (DIC), total alkalinity (TA) and spectrophotometric pH. I was also part of many red tide-related experiments, which sparked an interest in how water chemistry influences phytoplankton dynamics and vice versa. In Dr. Tang's lab, I look forward to studying the seasonality of nutrient uptake and marine productivity on the West Florida Shelf and its connection to broader ecosystem processes such as fish spawning.
