I am interested in a wide array of topics, including maternal effects, thermal ecology, and the evolution of life histories. I work with ectothermic vertebrates, and I use non-model systems to answer fundamental and applied questions in evolutionary ecology and conservation.
Previously, I worked with Dr. Ron Brooks (MSc. U. Guelph), Dr. Jeff Hutchings (PhD. Dalhousie U.), and Dr. Locke Rowe (PDF University of Toronto).
Most of my current research program is based out of Algonquin Park in Ontario.
Jessica hails from Scotland, where she studied at the University of Stirling and the University of Glasgow. Her previous work looked at the trade-off between reproduction and survival in wild Soay sheep. Here in Toronto, she has developed an interest in understanding the effect of temperature and climate change on embryonic development in the common snapping turtle & painted turtle. An area of study made even more important because the incubation temperature of the embryo permanently determines it sex. More broadly she is interested in understanding variation in life-history strategy, and how temperature affects life-history traits including offspring sex ratio.
Hollis is interested in how organisms diversify and evolve in dynamic geographic arrangements and environments. She holds a long-time enthusiasm for herpetology, as well as Chinese culture and language. An advocate for scientific outreach, cultural exchange, and international scientific collaboration, she will continue to travel to China and collaborate with researchers there.
Patrick is interested in evolutionary ecology, herpetology, conservation, and natural history. His research is based at the Algonquin Wildlife Research Station, where he focuses on the sensitivity to environmental change in the spotted salamander and the long-term life history study of turtles. Patrick is the recipient of several awards, including Canada’s New Noah Scholarship, and he is a strong proponent of scientific research, evidence-based policy, and stewardship programming to raise public awareness for conservation.

Robin is studying the evolutionary ecology of temperature-dependent sex determination through a combination of meta-analytic and experimental approaches. In his free time, Robin enjoys BBQing and riding the Leviathan at Canada’s wonderland.
Claudia is interested in the intersection of behavioural ecology, evolutionary ecology, and conservation biology. With a particular enthusiasm for herptiles, her research focuses on understanding the connection between hatchling turtle social behaviour and acoustic signalling (a.k.a. vocalizations!). She is also an advocate for science communication, education, and outreach. In her free time, Claudia enjoys wildlife photography, rock climbing, and playing volleyball.
Celina is studying the patterns and driving forces of body size gradients across latitude for turtles and other herpetofauna. Her research investigates why we often see larger turtles at higher latitudes and the ecological forces that are behind this body size cline. Celina is additionally interested in teaching and science communication, and generally sharing her love of the natural world. Her passion for studying herpetology and ecology also comes through in her favourite pastimes of wildlife photography and board games.

MEGAN GREISHAR, POSTDOC, 2017-2019
KATIE ZIEBARTH, MSc 2018-2020 (co-supervised by MARIE-JOSEE FORTIN)
MELANIE MASSEY, MSc 2016- 2018
Melanie is a critter enthusiast, artist, and public outreach advocate. During her time in the Rollinson Lab, she studied how the thermal environment of eggs affect sex ratios and development in Snapping Turtles. Now, she is doing a Ph. D. at Dalhousie University, where she is looking at how environmental variability affects developmental physiology of the zebrafish, a model organism. In addition to staring at eggs all day, Melanie is also working on an outreach initiative in Nova Scotia for Black, Indigenous, and people of colour youth, to engage them with Ecology.
