---

I’m an Assistant Professor in the UConn Department of Marine Sciences. My research focuses on developing and applying methods to measure gases and other biogeochemical tracers (e.g., stable isotopes) in the environment. Much of my research involves applying mobile and/or high throughput methods to study systems with high spatiotemporal variability. I have experience conducting research on topics ranging from marine productivity, to Arctic greenhouse gas emissions, to the environmental impacts of resource development and nutrient pollution. Check out my website and our lab Instagram for more info on what we are working on!
