I'm a soil microbial ecologist and biogeochemist interested in the stoichiometric theory and metabolic theory of ecology for microbes. I like to apply elemental ratios and concept of stoichiometry to predict soil ecosystem functions  from sub-cellular to ecosystem scales. I also want to apply metabolic theory of ecology using thermodynamics and the concept of energy to predict metabolic activity of microbes  in different environmental settings. Further, I'm interested in explore the plant-soil relationships in natural and agricultural systems, because this is very important to improve plant fitness and crop production, soil quality, water quality, and reduce potential environmental pollution in the era of climate change. 

I'm currently a postdoc Dr. DeAngelis's lab at University of Massachusetts Amherst.  You can contact me by email (xj.allen.liu@gmail.com). For publications and collaborators, please check my  Google Scholar, ResearchGate, or CV. Thanks for visiting!
