Personal profile

Research interests

I am a theoretical evolutionary biologist interested in the evolution and ecology of hosts and their parasites. 

I am currently a NERC Independent Research Fellow in the Department of Mathematical Sciences and the Milner Centre for Evolution at the University of Bath.

My research covers a broad range of topics in biology, including diversity, local adaptation, sexual selection, and the evolution of reproductive strategies (read a summary of my work or view my publications). I tweet (@bnashby) about my work and broad scientific issues, and I’m an ambassador for the “Ask for Evidence” campaign run by Sense about Science. My news page contains information on my latest papers and upcoming talks.

Willing to supervise PhD

Please get in touch ( if you would like to discuss PhD opportunities on host/parasite evolution.
