The Sinclair Lab at UWO
As a PhD candidate in the Sinclair lab, Iíve been studying the thermal biology of the insect immune system and the effects of low temperatures on immune activity and insect-pathogen interactions. Insects in temperate regions, such as southwestern Ontario, spend more than half of their lives overwintering; thus, their ability to survive low temperatures determines their success in these habitats. However, we know very little about how biotic pressures, such as parasites and pathogens, interact with low temperatures and change the way that insects survive and thrive. On the bright side, this gap has provided me with a broad and exciting PhD!
I work with several different species of insects, including the spring field cricket, Gryllus veletis, the woolly bear caterpillar, Pyrrharctia isabella, goldenrod gall flies, Eurosta solidaginis, acorn weevil larvae, Curculio glandium, and several species of yes-itís-a-real-insect-not-just-a-model, Drosophila. With this charismatic cast of characters, Iíve been exploring the interplay of immunology, physiology, ecology, and microbiomics, to understand the nature, and consequences, of the relationship between low temperatures and insect immunity.
The majority of this work is in preparation, so stay tuned for updated publications over the next several months! In the meantime, you can check out my other work below. Please feel welcome to email me.
