Min Xu

Title/position: Associate Research Fellow, Doctoral Supervisor

Min Xu was a Ph.D. in Marine Chemistry from Xiamen University (2018) and a postdoctoral fellow at Xiamen University and the University of Southern California (2018-2020). Focusing on the nitrogen biogeochemical cycle, she applies cutting-edge stable isotope methods to study the nitrogen transformation dynamics from estuaries to nearshore and open oceans, exploring the response mechanisms of ocean nitrogen processes and functional organisms under global change. Her main achievements include: 1) innovatively proposing the isotope matrix method to simultaneously analyze the rates of multiple nitrogen processes in the upper ocean; 2) for the first time, using isotope methods to confirm that the front of water masses transported by ocean currents is a hotspot for organic matter remineralization; 3) revealing the regulation mechanism of the interaction between light and substrate on the competition of photoautotrophic / heterotrophic microorganisms. She has led multiple projects, including the National Natural Science Foundation, the Key R&D Program of Hainan Province, the Postdoctoral Fund, and the Postdoctoral International Exchange Program. She has published nearly 20 SCI papers in international journals such as Water Research, Limnology and Oceanography, and Geophysical Research Letters."

Research Interests

Xu focuses on the dynamic processes of nitrogen cycling in different aquatic environments, using techniques such as isotope tracing, flow cytometry, nano ion mass spectrometry, and bioinformatics. The main research topics include but are not limited to:

(1) Rates and regulatory factors of nitrogen cycling dynamics (especially in the photic zone and deep sea);

(2) The role of microorganisms (phytoplankton, nitrifying bacteria, viruses, etc.) in nitrogen cycling and how they regulate the biogeochemical stoichiometry of the ocean;

(3) Coupling studies of nitrogen with carbon, phosphorus, metals (iron, copper, etc.);

(4) Exploring the cycling of nitrogen-related elements and functional biological responses in different aquatic environments under global change at different levels such as communities and cells.

Welcome new participants, including Master's and doctoral students with knowledge backgrounds in marine chemistry, marine biology, environmental science.
