Biographical details

Kevin Simonin holds a BA in Plant Biology from the University of Montana, a MSc in Forest Science from the School of Forestry, Northern Arizona University, and a PhD. in Integrative Biology from the University of California, Berkeley. During his PhD Kevin developed a new understanding of where plants obtain their water and how leaf water use efficiency changes as leaves differ in size and longevity. Kevin's research interests weave together his training in forest ecosystem ecology, plant physiological ecology and stable isotope biogeochemistry.

Research interests

Currently Kevin's reserach program focuses on 2 broad areas: (1) plant water and carbon balance in response to a changing climate and (2) using stable water isotopes to quantify the influence of climate change on plant water use and ecosystem hydrology. A general theme in this research is the use of biophysical models describing the coordination between plant water loss and carbon gain in order to assess the impact of climate change on plant productivity, water use efficiency, and ecosystem hydrology.The research program embraces the idea that increasing our understanding of the biophysical processes that define plant-atmosphere interactions is of critical importance for understanding how natural and human-reconfigured ecosystems respond to climate change.
