Dr. Chen is currently a senior research scientist with the Canada Centre for Remote Sensing (CCRS) in Ottawa, Canada. He received a B.Sc. degree in 1983 in Meteorology from the Nanjing Institute of Meteorology, China, and a Ph.D. in 1997 in Bio-meteorology and Soil Physics, from the University of British Columbia, Canada.

He is closely involved with the Terrestrial Carbon Observation (TCO), a UN Integrated Global Observing Strategy Partners (IGOS-P) initiative. He has also been an IPCC expert and government reviewer for the IPCC special report of "Land Use, Land-Use Change and Forestry", and the 3rd IPCC Assessment Report.

As a team leader, Dr. Chen and eight team-members in CCRS are responsible for carrying out researches for better understanding and quantification of carbon and water cycle of Canadian terrestrial ecosystem, as a part of Canada's climate change science and policy research. This team also maps biophysical parameters critical to carbon and water cycle studies, such as leaf area index, clumping index, insects-defoliation, water body distribution, wetlands, and biomass. He is the principle investigator of following proposed projects:

• "High-Resolution Carbon Budget of Canada's Forests", funded by Canadian federal government action plan 2000 for climate change, for the duration of 2001/02-2004/05.
• "National carbon budget of Canada's forests and forested wetlands at the 1-km resolution", funded by the Panel for Energy Research and Development (PERD) for the duration of 2001/02-2004/05.
• "Integrated National-scale Carbon And Hydrological cycles Study (INCAHS)", funded by CCRS for the duration starting from April 2001.
• "Mapping Biophysical Parameters over the Mackenzie Basin for Hydrological-Climate Studies", Mackenzie GEWEX Study-phase 2 (MAGS-II) 2001/02-2004/05.

In addition, Dr. Chen is also a co-investigator of the following projects:

• "Climate Change and Ecosystem Impact (CCEI)", funded by the Long term Space Plan 3 of Canadian Space Agency for the duration of 2001-2010.
• "Northern Biosphere Observation and Modelling Experiment (NBIOME Phase II)", funded by NASA for the duration 2000-2002.
• "Biomass and Wetlands Maps of the North American Boreal Zone from JERS-1 and ERS-1/2 SAR Imagery", funded by NASA, for the duration of 2001/02-2004/05.
