Research themes:
My research focuses on linking measurements from earth observation platforms to photosynthesis on the ground in order to better understand, map, and monitor carbon exchange between ecosystems and the atmosphere. I hold an M.Sc. in Natural Resource Science from McGill University, and a Ph.D. in Physical Geography from the University of Toronto. I also completed a postdoctoral fellowship in the School of Earth, Environment & Society at McMaster University. My work involves characterizing spatial and temporal variability in vegetation structure, function, and physiology across scales ranging from individual leaves and ecosystems, to the global Earth system. My research is motivated by a desire to contribute to solving the challenges posed by climate change, in hopes that we can better monitor, predict, and mitigate the impact of this global threat.
