Damon Matthews is a Professor and Research Chair in Climate Science and Sustainability at Concordia University. Damon holds a PhD in climate science from the University of Victoria, and is a member of the College of New Scholars, Artists and Scientists of the Royal Society of Canada and a Review Editor for the upcoming Sixth Assessment Report of the Intergovernmental Panel on Climate Change. He has published more than one hundred research papers on topics ranging from quantifying the remaining carbon budget to assessing equitable approaches to allocate emission allowances to individual countries. He is internationally recognized for his work in policy-relevant climate science, as well as for initiatives such as the Climate Clock that use digital visualization and web-based technologies to motivate and accelerate climate action. Damon is the Scientific co-Director of Sustainability in the Digital Age, and directs the NSERC CREATE in Leadership in Environmental and Digital Innovation for Sustainability (LEADS) program, which aims to train graduate student researchers at the intersection of sustainability science and digital innovation.

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
  • Assessing climate impacts as a function of global mean temperature change
  • Assessing national contributions to and responsibility for global warming

Current Climate Lab student projects

  • Seth Wynes (Postdoc): Public understanding of climate change and other global risks
  • Jen Gobby (Postdoc): Understanding social drivers of systemic change 
  • Mi Lin (Postdoc): Towards science-based biodiversity pathways for Canada
