  • Education / Bio

    Dr. Damon Matthews is Associate Professor and 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, he held a post-doctoral fellowship at the University of Calgary, and worked as a post-doctoral researcher at the Carnegie Institution at Stanford. Dr. Matthews currently teaches courses on the climate system, climate change and environmental modelling at Concordia University. 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 holds several current research grants for projects to investigate uncertainties associated with the climate response to cumulative greenhouse gas emissions. He has published a number of research papers in the area of global climate modelling, with particular emphasis on the role of the global carbon cycle in the climate system, estimating allowable emissions for climate stabilization, and understanding our commitment to long-term climate warming. Dr. Matthews was a recent member of the U.S. National Academy of Sciences "Committee on Stabilization Targerts for Atmospheric Greenhouse Gas Concentrations," 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:

    • Modelling the influence of past and future land-use change on climate
    • Estimating the climate response to cumulative greenhouse gas emissions
    • Predicting allowable emissions for global climate change policy targets
    • Modelling the atmospheric sinks for methane and nitrous oxide
    • Assessing climate impacts as a function of global mean temperature change
