Specific Research Area / Project:
Ecosystem modeling

Undergraduate Institution:
Fudan University in China

Research Profile:

My research in centered around improving the current understanding of, and ability to model carbon dynamics of the terrestrial ecosystem and climate-carbon feedbacks. I am broadly interested in developing hypotheses regarding the importance of different processes and the underlying mechanisms in both short and long term biosphere-atmosphere interactions. Particularly, I focus on the boreal ecosystems and the soil systems and use computer models in combination with a variety of data sources (eddy-covariance towers, remote-sensing data and field measurements) to explore the fundamental drivers and mechanisms of biogeochemical processes.

About Me:

Born and raised in a remote inland city in China, I drafted my young career to be a get rich quick scheme. During my trip to Europe in my undergrad I realized that good pay was not worth it and there are much more out there to experience and to enrich one’s spirit. The constant curiosity about the world drove me to study environmental sciences. Here at Purdue and in the ESE program, I find promising opportunities to bridge what I have learned and the change I want to see in reality. The interactions with ESEers who share common interests with me and the diversity of perspectives generated by the unique interdisciplinary platform all making my PhD study a rewarding period.
