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 nutrient retention and biomass production 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 microbial 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 under increasing environmental stress, such as drought, warming, nutrient loss, and so on. 

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 or ResearchGate.  Thanks for visiting!
