Heath MacMillan (Principal Investigator)

I completed my PhD at the University of Western Ontario (London, Canada) with Brent Sinclair and Jim Staples. My first postdoctoral fellowship was with Johannes Overgaard at Aarhus University (Aarhus, Denmark), which was followed by a Banting postdoctoral fellowship with Andrew Donini at York University (Toronto, Canada). I strongly recommend all of these individuals as mentors. 

I am broadly interested in the mechanisms underlying thermal performance and stress-related injury. My primarily focus is on terrestrial arthropods, but I also dabble in projects on aquatic crustaceans.

See the Publications page for a look at our research history or the Research page to see what we are currently up to in the lab. Prospective lab members should see the Positions page.

Genevieve.png

Genevieve Ferguson (Postdoctoral Fellow)

Genevieve completed a PhD at Carleton University in Sue Bertram’s lab (2018) examining how the acoustic social environment and anthropogenic noise pollution experienced during rearing affected both development and adult behaviour in the fall field cricket (G. pennsylvanicus). She received her MSc in Human Biology from the University of Indianapolis, with a focus on forensic anthropology. Genevieve has a wide range of research interests and her Postdoctoral work is focusing on cricket growth and survival within an industry setting.

Hannah Davis (PhD candidate)

Hannah joined the MacMillan Lab as a PhD student after completing her MSc in Biology at the Freie Universität Berlin, where she worked on social immunity in the termite Reticulitermes flavipes. She is interested renal adaptation and acclimation to cold stress in insects, using Drosophila melanogaster as a model in the first phase of her research. Her other interests include protozoa, viruses, and anything with six or more legs.

Kaylen Brzezinski (MSc candidate)

Kaylen joined the MacMillan lab at Carleton University following the completion of her undergraduate degree in Biology at Queen’s University. During her undergraduate career, she successfully completed an honour’s thesis project under the guidance of Drs. Adam Chippindale and Mel Robertson. There, she examined the evolution of anoxia tolerance in populations of Drosophila melanogaster. Now, as a Master’s student in the MacMillan lab, Kaylen is shifting gears, focusing instead on locusts in order to determine how temperature affects paracellular barrier permeability in gut epithelia.

Ravneet Hansi (HBSc)

Ravneet is a fourth year honours biology student who joined the MacMillan lab in the Fall of 2018. Ravneet is interested in finding out whether or not there is a threshold temperature at which the paracellular barriers within Drosophila melanogaster stop working due to cold stress.


Jessica Carrington (HBSc)

Jessica is a cellular and molecular biology student who joined the MacMillan lab in the summer of 2018. Currently, Jessica is using locusts (L. migratoria) as a model to develop high-throughput assays for cellular apoptosis following cold stress. In particular, Jessica is exploring the role of potassium levels in causing apoptosis, with a specific focus on the nervous system.


Serita Headshot.jpeg

Serita Fudlosid (HBSc)

Serita joined the MacMillan lab in 2018 as an honours undergraduate thesis student. She is studying biology with a minor in food science. In the lab, Serita is quantifying the effects of neuropeptides on chill tolerance, using Drosophila melanogaster as a model.

Mahmoud El Saadi (Research Assistant)

Mahmoud joined the MacMillan lab in the fall of 2017 as a vollunteer. Currently, Mahmoud is a Research Assistant working to optimize cricket growth and survival along with Dr. Genevieve Ferguson (above). Mahmoud is also conducting research on how repeated cold exposures affect hemolymph ions, survival, and reproduction in D. melanogaster. Mahmoud plans to do his Honour's thesis in the summer.
