I have been a professor at UCalgary for 25 years, conducting research on a variety of aspects related to water quality and pollution in southern Alberta shallow lakes. My interests lie in understanding the effects of chemicals and invasive species on natural populations. I am passionate about increasing the public's awareness and literacy for all things that involve water. I publish in a wide range of journals around the world, sit on an editorial board (Aquatic Conservation: Marine and Freshwater Ecosystems) and review manuscripts and grant proposals for Canadian and US agencies. Photography is one of my hobbies - I try to bring an different visual perspective to my lectures and presentations with my images.
