I am a paleoclimatologist and paleoecologist at the British Antarctic Survey and an adjunct professor at the University of Toronto.

I use lake sediments to understand the impact of man on the environment, investigating the environmental effects of anthropogenic climate change, prehistoric land use, and long-term (>10,000 year) natural climate variability. 

I have been working for over 20 years in high latitude and mountainous regions (e.g. the Canadian Arctic, Svalbard, Greenland, Alaska, sub-Antarctic islands, Himalayas, Alps, Canadian Boreal Forest). 

I am a painter and printmaker. I work mostly with watercolours and intaglio printing techniques to create landscape works on paper of places I live, work, or visit. 

I work as an expedition educator with Students on Ice in Greenland and the Canadian Arctic. I have also worked with different media organizations and initiatives (BBC, CBC, film, podcasts, virtual classrooms, MOOCs, etc.) to help diverse audiences understand the impacts of climate change in the polar regions.
