Research Interests

How does the physiology of populations set their geographic distribution, and how can this be modified via acclimation and adaptation?  I'm working to address these questions using (mostly) mosquitoes. Over 3500 species occur worldwide, 200 of which are in the US, and many of these transmit major diseases. 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. 

Conservation Reports of the Southwest 

The reports below are compilations of final student papers around the southwestern US - focused themes of First Year Experience (FYE) courses taught in previous years. Please contact me for further details or if you wish to use any part of these materials. 

2016 FYE -- Sustainability of the Salton Sea: A review of the environmental, economic, and social climate around California's largest saline lake 

2017 FYE -- Crested Butte: Loving it to Death

Activities & Interests

I enjoy teaching classes that involve conservation and sustainability. I have created several classes over the years that have allowed students and I to explore major conservation issues (the Salton Sea, outdoor recreation in Colorado), and in every ecology class we spend time investigating and participating in local restoration, conservation and sustainability efforts.

On my free time I love to garden, go on road trips, hike, ride my bike, backcountry ski, backpack, all with my dog!
