Peter Leavitt

Director

Peter.Leavitt@uregina.ca

Peter R. Leavitt is the Canada Research Chair in Environmental Change and Society, Professor of Biology, and founding Director of IECS and its predecessor EQAL. Peter has experience in national leadership (Executive of SCL; Director CIEE), science communication (SCL media officer), societal governance (Board of ASLO), scientific conferences (SCL, ASLO, SIL), grant evaluation (US NSF), revenue generation (>$20M in grants), publication (>125 papers), and science adjudication (editorial boards of Ecology, and 4 others). Research in Leavitt’s University of Regina Limnology Laboratory combines experiments, modeling, paleolimnology, and long-term (20 yr) ecological research to quantify the factors that regulate the structure and function of lakes, and improve strategies for their protection.

Gavin Simpson

Environmental Scientist (Numerical)

gavin.simpson@uregina.ca

Gavin Simpson is Quantitative Environmental Scientist at the IECS and holds Adjunct Professor positions in the Department of Biology, and the Faculty of Graduate Studies and Research at the University of Regina. Gavin earned a B.Sc. (Hons.) in Environmental Geography and a Ph.D. in Geography from University College London, UK. He is a quantitative ecologist and palaeoecologist with over a decade of experience in research and consultancy. Gavin's research interests include dynamical systems ecology and abrupt ecological change, climate change effects on arctic lakes, nitrogen pollution of remote oligotrophic lakes, and recovery of lakes from acidification and eutrophication. Gavin sits on the editorial board of the journal Scientific Data. He contributes to a number of open source software initiatives and has written or contributed to a number of packages for the R statistical software.
