Brief Introduction

Prof. Kai Xue obtained his ph.D degree in soil science at Cornell University in 2009 and worked as a postdoctoral researcher in Institute for Environmental Genomics after that. He joined the University of Chinese Academy of Sciences (UCAS) since 2017 and entered into the newly established tenure-tracked system in 2018. His research focus on soil microbial ecology, including spatial pattern of microbial communities and belowground mechanisms, microbial roles in restoring degraded grassland and regulating ecosystem feedback to global climate change, by using metagenomic techniques (e.g. functional gene microarray and high-throughput sequencing). He published more than 70 papers in academic journals, including PNAS, Nature Climate Change,eLife, mBio,Soil Biology and Biochemistry, Applied and Environment Microbiology.

Professor,  Dec, 2021- Present

Tenure-tracked system, September, 2018- Dec, 2021
Associate Professor,  April, 2017- Dec, 2021

Focusing on soil microbial ecology, especially roles of microbes in restoring degraded grassland in Tibet Plateau, and regulating ecosystem feedback to global climate change.


Institute for Environmental Genomics, Norman, OK, USA
Postdoctoral Research Fellowship, Feb, 2009-March, 2017

Investigated influences of agriculture managements on crop yield, greenhouse gas emissions, soil attributes and functional genes in microbial community for nutrient cycling. Assessed soil and plant changes induced by aboveground biomass removal for producing biofuel or hay in grassland. Collaborated with multi-disciplinary teams (ecology, modeling, statistics and bioinformatics)  to study ecosystem responses to global climate changes, including soil processes and microorganisms by using metagenomic techniques (i.e. microarray and illumina sequencing).


Cornell University, Ithaca, NY, USA Research Assistant, Aug, 2004-Jan, 2009

Conducted field studies to investigate effects of transgenic corn, Cry3Bb1 Bt corn against corn rootworm, on crop residue decomposition, tissue lignin concentration and associated microbial decomposer communities. Evaluated persistence of insecticidal Cry3Bb1 protein in soils, its within seasonal dynamics and decomposition in Bt corn residues by ELISA. Performed greenhouse experiment to investigate carbon allocation within plant and tissue lignin content in Bt and NonBt corn as infested by corn rootworm . Measured partitioning of photosynthate C to various plant components as short-term C allocation by 13CO2 pulse-labeling system. Investigated public perception towards transgenic food in China.
