Dr. Damon Matthews is Professor and Tier 1 Concordia University Research Chair (Climate Science and Sustainability) in the Department of Geography Planning and Environment. He obtained a B.Sc. in Environmental Science from Simon Fraser University in 1999, and a Ph.D. in Earth and Ocean Sciences from the University of Victoria in 2004. Prior to joining Concordia University in January 2007, Dr. Matthews held a post-doctoral fellowship at the University of Calgary, and worked as a post-doctoral researcher at the Carnegie Institution at Stanford. His research is aimed at better understanding the many possible interactions between human activities, natural ecosystems and future climate change, and contributing to the scientific knowledge base required to promote the development of sound national and international climate policy. Dr. Matthews has published more than 90 research papers on topics such as the climate response to cumulative carbon emissions, estimating allowable emissions for climate targets, and exploring equitable ways of sharing the global emissions quota. Dr. Matthews is a member of the College of New Scholars, Artists and Scientists of the Royal Society of Canada, serves as Concordia's scientific liaison to Future Earth, and was a contributing author to the Fourth and Fifth Assessment Reports of the Intergovernmental Panel on Climate Change.

Graduate student opportunities

I am looking for graduate students interested in learning about global warming and climate modelling, and exploring the role of greenhouse gas cycles in the context of recent and future climate change. Potential students should have good quantitative skills, and some knowledge of computer programming would be an asset. Possible research projects include:

  • Estimating the climate response to cumulative greenhouse gas emissions
  • Predicting allowable emissions for global climate change policy targets
  • Projecting future changes in the availability of outdoor skating
  • Assessing national contributions to and responsibility for global warming
  • Modelling the atmospheric sinks for methane and nitrous oxide
  • Modelling the influence of past and future land-use change on climate
  • Assessing climate impacts as a function of global mean temperature change

Current Climate Lab student projects

  • Martin Leduc (Post-doc): Analyzing the climate response to cumulative greenhouse gas emissions
  • Christopher Simmons (Post-doc): Role of peatland carbon accumulation in Holocene climate change
  • Antti-Ilari Partanen (Post-doc): Climate and health implications of aerosol mitigation strategies 
  • Jean-Sebastien Landry (Visiting PhD student): Fire and other natural disturbances in the climate system
