I am an evolutionary biologist interested in the evolution and maintenance of cooperation.

Evolution of nitrogen-fixing symbioses in angiosperms.

Everywhere we look in nature, we see successful cooperation. Yet, cheaters and defection undermine cooperative interactions and can cause them to break down.

So why does cooperation evolve? How is it stabilised? When is it lost? These are some of the questions I am interested in.

I study both mutualisms – cooperative interactions between species – and cooperation within species. I am also interested in social evolution more generally. You can find more information about my research interests here.

Currently, I am a Royal Society Newton International Fellow at the Department of Zoology, University of Oxford, working in the Social Evolution group with Prof. Stuart West.
