Climate Change & Impacts Lab
@ UQAM

We study how climate change interacts with the terrestrial systems that underpin human thriving, like agriculture, vegetation and water resources.

Interested in climate impacts research? The group is presently growing! Reach out if you're interested in joining the group as a Bachelors, Masters or PhD student.



Research

Our group merges statistical analysis of observational datasets with complex and simple climate models to investigate:

Hydroclimate change

How the intensity and intermittency of precipitation events are changing as the climate warms; the physics underlying these changes; and whether climate models simulate these processes accurately.



Land–atmosphere water and energy exchange

How warming alters what happens to precipitation after it reaches the land surface; how the relationship between drought and heat evolves under warming; and whether vegetation buffers or amplifies the drying effect of warming.



Climate impacts on agriculture and water resources

How changes in precipitation and evaporation characteristics affect the continental water balance; and whether crop carbon-fertilization benefits might offset the impacts of extreme heat and drought.

The group is growing! Please feel free to email me regarding undergraduate, graduate, or postdoctoral opportunities.


Postdoctoral Research


There are a few postdoc possibilities to work with our group:


1. NSERC/FRQNT Fellowships

We could collaborate to prepare a strong application, and fellowships give you the greatest research freedom.


Graduate Student Research


Graduate students can join the lab through the MSc and PhD programs, pending funding.



Undergraduate Research


If you are an undergraduate student, you may join the group as a research assistant (pending funding) or apply to work in the group for a summer via the NSERC USRA program.
