I have had the rare privilege to turn my childhood fascination into a career. I grew up catching snakes, turtles and toads in the forests and creeks near my house. As a professor, I have the opportunity to share my passion for these animals and their conservation with students in the classroom and in the field.
I did my undergraduate degree at the University of Guelph. There I met herpetologists Ron Brooks and Jim Bogart, and so began my formal training in herpetology. I did my MSc under Ron’s supervision at Guelph, studying the population ecology of Spotted Turtles at their northern range limit. In the summers, I taught biology to kids at a canoe-tripping camp, and so got to combine my interests in biology, teaching, and the outdoors.
Between my MSc and PhD, I worked as a Lab Coordinator in the Cryobiology Lab at Miami University in Oxford, Ohio, USA. I worked with Rick Lee and Jon Costanzo, and their graduate and undergraduate students. I learned a whole new set of skills and gained an appreciation for physiological-ecology and the incredible adaptations that herps have for surviving winter.
After three years in the Cryo Lab, I decided it was time for me to return to graduate school, to answer the questions about latitudinal variation in turtle life histories that arose during my MSc research. So I left Ohio and moved to South Carolina to study the population ecology of Spotted Turtles at their southern range limit. I worked under the supervision of Tim Mousseau, an ex-pat Canadian, at the University of South Carolina in Columbia.
After completion of my PhD, I moved to Long Island, New York to live with my husband, Dr. Thomas Merritt who was doing a post doc at Stony Brook University (he is now a prof here at Laurentian in the Department of Chemistry & Biochemistry). While in New York, I worked as an Adjunct Professor at Long Island University and as a research associate at Applied Biomathematics.
Then, in spring 2004, I was offered the faculty position here at Laurentian University, and so I moved back home to Ontario after 8 years in the USA. I have been a professor at Laurentian since July 2004.

My research program combines field and lab-based approaches, and basic and applied science. Projects in my lab address questions in the fields of population ecology and conservation biology of reptiles, and the application of ecological data to tests of mitigation and recovery actions. My work focuses on demography, maternal investment, road ecology, spatial ecology and habitat selection. Physiological research examines questions about bioenergetic, fitness, and thermoregulatory consequences of certain behaviours, particularly summer and winter dormancy, in reptiles.
Our research is funded primarily by NSERC, and previously by the Ontario government through the Species at Risk Research Fund (SARRF) and the Species at Risk Stewardship Fund (SARSF). We have also received support from Environment Canada's Habitat Stewardship Program (HSP) and the Canadian Wildlife Federation. We are grateful to our industry and government partners, especially Ontario Parks, for their financial and in-kind support.

July 2018: Exciting news from NSERC! Our CRD grant with Bruce Power was funded. This project will examine how changes in lake levels impact turtle spatial ecology and nest site selection, and will help to fulfill the environmental responsibility mandate of Bruce Power, who have been amazing partners over the past several years.
March 2018: Jackie received the Laurentian Research Excellence Award at the Research Week Gala and Awards Ceremony. Jackie also received a Mentorship Award from Magnetawan First Nation for her contributions to their long-term Species At Risk program.
Thanks to to the Team for their amazing contributions to these honours -- I couldn't get here without you!
November 2017: Jackie has been using her sabbatical time to try her hand at creative writing. She published a couple of articles in the online magazine called The Conversation.
