Assistant Professor

Research Interests

physiological ecology of animals

insect adaptations to extreme environments

mosquito biology and ecology

populations and climate change

How does the physiological make-up of individuals and populations set their geographic distribution, and how can this make-up be modified via acclimation and adaptation? Why are some populations more successful than others at dealing with climate change? I'm working to address these questions and others using mosquitoes. Over 3000 species occur worldwide, 200 of which are in the US, and many of these transmit diseases important to humans and other animals. Furthermore, species vary widely in terms of their ecology and life history. These factors make mosquitoes particularly attractive study organisms for exploring the physiology of climate change.

Activities & Interests

I love to travel, grow plants, raise chickens, make cheese and drink good wine. And hike and bike and camp and walk dogs. And catch mosquitoes. And ride motorcycles. And the list goes on.
