Biographical details

I hold a BSc in general biology from Beijing Normal University (China), a MSc in plant ecology from Acadia University (Canada), and a PhD in plant ecophysiology from the University of Pennsylvania (USA). I am broadly interested in the patterns and processes that govern plant-environment interactions at several scales (i.e. organismal, ecosystem and global). The major tool that I employ in my research is stable isotope analysis, with the aid of which I am particularly interested in addressing questions revolving some key physiological and ecological processes that regulate carbon and water exchange between plants and the atmosphere.

Research interests

My research interests include:

  • Using isotope signatures archived in plant tissues (i.e. tree rings) to gain retrospective insight into eco-physiological response of plants to environmental change
  • Understanding the relevance of plant physiological activities including carbon uptake, transpiration, and non-structural carbohydrate turnover to the determination of oxygen isotope signal in various plant pools (i.e. leaf water, stem cellulose, phloem sap organic matter)
  • Exploring plant-atmosphere exchange of water and carbon through high frequency laser isotope measurements coupled with gas exchange measurements on crop plants.
