Eric joined Forest Research in November 2000. He has a research background in plant ecophysiology and particularly in functional relations between environmental variables, plant structure and function. He was awarded a MSc in Forest Biology from Henri Poincaré University (Nancy, France) (1992) and a PhD from Blaise Pascal University (Clermont-Ferrand, France) (1996), where his research focused on long-term effects of climate changes on temperate grass sward ecosystems. He did post-doctoral research at the University of Antwerp (1998-2000) and at Forest Research (EU Marie Curie Fellowship) on Functional-Structural model developments for trees and bushes.
Working in particular on:
- Process-based modelling of water and carbon dioxide fluxes and energy and carbon balances of temperate forest ecosystems.
- Assessing risks of climate change to forest function.
I am also developing new mathematical algorithms to extract canopy and forest structural components from terrestrial and airborne LiDAR scans to underpin modelling and carbon stock assessment.
- Climate change impacts and adaptation (FORCCAST)
- Climate change mitigation (ManForC)
- Short rotation forestry
