Personal profile

Personal profile

I am an Assistant Professor in the Department of Natural Resources and Environmenal Sciences at the University of Illinois at Urbana-Champaign. I am also a Blue Waters Professor with a joint appointment with the National Center for Supercomputing Applications (NCSA). I am a computational environmental scientist studying underlying processes of vegetation-hydrology interactions (i.e. ecohydrology, water-ecosystem-food nexus) for natural and agricultural ecosystems. My current research has a particular emphasis on the impacts of hydro-climate change on vegetation dynamics and crop productivity in tropical and temperate regions.The goal of my research is to increase our society’s resilience and adaptability to maintain sustainability of ecosystem services, food security and water resources under the influence of climate change and anthropogenic drivers (e.g. land use change, increased population and food demands), which directly or indirectly impacts the livelihood and wellbeing of billions of humans.

More information can be found at: http://faculty.nres.illinois.edu/~kaiyuguan/.

I have plans to recruit graduate students and postdocs with full supports in the coming years in the area of "crop remote sensing and modeling." Thus, if you are interested in these opportunities, please contact me with your CV.
