Xinning is an environmental microbiologist in the Department of Geosciences at Princeton University. She obtained her B.S. in Biological and Environmental Engineering from Cornell University in 2004 and Ph.D. in Environmental Science and Engineering from the California Institute of Technology in 2010. Her research interests encompass the coupling of biogeochemical cycles through microbial physiology, the impact of microbial metabolism on stable isotope records, co-evolution of microbial life and the geochemical environment, and microbial nutrient acquisition strategies.

I started my education in France, where I studied biological and geological science. After a MSc. in chemistry, I traveled to cold French Canada where I obtained my Ph.D. in biogeochemistry, studying the importance of vanadium in boreal cyanolichens. I continued my training during a first postdoc in soil ecology by studying nitrogen acquisition in boreal forest before I started my present position as a postdoctoral fellow in the Geosciences department of Princeton University.

In the Zhang lab, I am using my multidisciplinary background and training to conduct research on the importance of nitrogenases in coastal environment and sediment. I am also continuing my research on alternative nitrogenases in boreal ecosystems with Prs. Lutzoni (Duke University) and Bellenger (Université de Sherbrooke).

Dr. Jared Wilmoth studies geological chemistry and microbiology using high-resolution chemical and molecular characterization techniques. The major focus of his experimental research is on investigating and understanding how microbial/environmental interfaces regulate greenhouse gas emissions from wetland and peat soils that undergo dynamic redox oscillations. He earned his PhD in Soil Science (biogeochemistry) from the University of Georgia, Athens Georgia, USA and has completed postdoctoral research at Oak Ridge National Laboratory, TN, USA in the Biological and Nanoscale Systems Group, Biosciences Division.

Carol graduated with a B.S. in Chemical and Biological Engineering in 2017. Carol's work aimed at understanding the diversity of canonical Mo and alternative nitrogenases in model microbial communities.
 
 
 

Allison Lee

 
Position: Undergraduate
Email: allisonlee@princeton.edu
Allison is an undergrad majoring in Ecology and Evolutionary Biology. During 2016-2017, she studied the mechanisms underlying 15N fractionation in model N fixers, focusing on growth rate and Fe availability. She also doesn't mind accompanying Xinning for a day of field work in the mud!
