Weiyi Tang, Harry H. Hess Postdoctoral Fellow

Weiyi Tang

Position: Research Staff
Title: Postdoctoral Research Associate
Area(s):

  • Nitrification
  • Denitrification
  • Anammox

Research summary: Weiyi Tang is interested in how nitrogen is supplied, transformed, and removed in the global ocean and how marine nitrogen cycle is connected to the carbon cycle and Earth’s climate. During his PhD, Weiyi developed and applied high-resolution observing methods, molecular techniques and machine learning algorithms to explore marine nitrogen fixation and its impact on marine productivity in the world’s ocean. Joining the Ward research group, Weiyi will study the broad nitrogen biogeochemical pathways in addition to nitrogen fixation (e.g. nitrification, denitrification, anammox).

Xianhui (Sean) Wan

Position: Research Staff
Title: Postdoctoral Research Associate
Area(s):

  • Stable Isotope
  • Nitrogen Cycle
  • Nitrous Oxide

Research summary: My research focuses on the marine nitrogen and carbon cycles, particularly in microbe-phytoplankton interactions and nitrous oxide (N2O) production in different marine systems (from the eutrophic coastal zone to the oligotrophic open ocean). To disentangle complex C & N dynamics, I take advantage of multiple C, N and O stable isotope approaches (including both natural abundance and isotope labelling technique) to examine rates of C and N transformations. Main target of my research is to better understand the role of the ocean in regulating atmospheric CO2 and N2O during the intimate coupling of C & N cycles and how these processes respond to anthropogenic forcing and natural variabilities.
