Dr Tobin Northfield ~ Adjunct Senior Lecturer

I am broadly interested in the evolutionary ecology of ecological communities, and my background is in entomology and statistics. I use theoretical and empirical methods and try to combine the two as often as possible. My empirical research generally focuses on insect communities, but I have also worked on other systems through collaboration. Some of my research interests include:

How does coevolution alter the effects of climate change on ecological communities?

How do community structure and interactions alter ecosystem functions, such as natural pest control by insect predators?

How does climate change alter ecosystem functions provided by ecological communities?

How do land management regimes influence biodiversity conservation?

More information on me and my labgroup is available at northfieldlab.org
