Hi!

My name is Heather, and I am a PhD student in the Biology Department at Carleton University in Ottawa, Canada where I study how an individual's environment influences their behaviour. Most of my research is done in Trinidad, The West Indies, but I love to travel to all different kinds of ecosystems.

I also work on CurioCity as a Science Editor and to help bring you the most interesting stories and breakthroughs happening in science! I volunteer with Let's Talk Science as an outreach volunteer in Ottawa and rural Ontario. 

I love to observe and photograph the amazing animals and landscapes from around the world.
