I am interested in the causes and consequences of variation in species’ life histories and seasonal phenologies—particularly as these traits relate to species interactions. A primary application of my research is in understanding ways that climate change and other forms of global change affect pollinators (especially native solitary bees) and pollination. My work so far has focused mainly on bees and plants in natural habitats, but I am also interested in how better knowledge of native bee ecology can benefit agriculture.


Gail MacInnis
Doctoral student, co-supervised by Prof. Chris Buddle (McGill), since 2015
E-mail: gail.macinnis “at”

Gail is interested in how bee diversity affects the yield and quality of agricultural food crops. She is studying pollen deposition and foraging behaviour of wild and managed bees and their efficiency as pollinators of commercial and organic strawberry crops.


Cécile Antoine
Doctoral student since 2017
Office: GNN 353
E-mail: cecile.antoine.31 “at”

Cécile is interested in the factors that limit populations of wild bees and hence the pollination service provided by these bees, in an agricultural environment. She is working more specifically on populations of solitary ground-nesting bees in the margins of farms fields that differ in farm management.

Sebastien Rivest

Sébastien Rivest
Doctoral student since 2018
Office: GNN 353
E-mail: srive028 “at”

Sébastien is interested in the defense mechanisms used by plants to protect their pollen. He will examine the causes of the presence of plant defense compounds in pollen by comparing their effect on pollinators, pollen thieves, and pollen microorganisms, and evaluate their consequences by looking at their role in the evolution of the genus Osmia.

Evelyn Bragion

Evelyn Bragion
Doctoral student, co-supervised by Prof. Risa Sargent, since 2019
Office: GNN 353

Evelyn is interested in how climate change can affect spring ephemerals by altering their interaction with pollinators and overstorey plants. She is working in Gatineau Park.

Gabriel Gauthier
Master’s student since 2018
Office: GNN 353
E-mail: ggaut049 “at”

Gabriel is fascinated by the complexity of ecological communities. He will be examining the indirect effect of temperature on wild bee fitness through plant-pollinator phenological mismatch. To do so, he will be studying high-altitude wildflower and bee communities around the Rocky Mountain Biological Laboratory in Colorado. Gabriel likes baby goats, too (but who doesn’t?).


Michelle Hotchkiss
Master’s student, co-supervised by Prof. Alex Poulain, since 2018
Office: GNN 353
E-mail: mhotc015 “at”

Michelle is interested in bumble bees and the microbes that call their guts home. For her M.Sc. research she will investigate how pesticides alter the structure of bumble bee gut microbiomes, how a pesticide-exposed gut microbiome affects bumble bee fitness, and if pesticide-exposed microbiomes can recover after pesticide exposure.


Lydia Wong
Master’s student since 2018
Office: GNN 353
E-mail: lydiahagar.wong “at”

Lydia is investigating the effects of drought on Colorado bees. In the past, she has worked on figuring out why solitary bee species nest when they do, and on which native and non-native plants are favoured by native bees in the city of Toronto.

Xiaoyue (Sherry) Wu
Co-op and honours student, 2019-2020

Sherry’s focus is on developing methods for locating ground-nesting bees, with the goal of facilitating future research. She is also interested in studying the complexities of native bee communities in agricultural environments.



Luca Fiorindi
Lab volunteer since 2018

Luca is an undergraduate student in his 4th year of a major in environmental studies with a minor in biology. His particular interest is in the effects climate change will have on native plants and pollinators.

Lab dog

Oscar is new to the lab and we are still figuring out what direction his research should take, but he is currently more interested in empirical field-based research than in development of theory.
