PeerJ Author & Reviewer

Summary

I find animal behaviour of all colours fascinating and am happy to devote hours and hours to what could be perceived as tedious observation of animals doing pretty much nothing.

I have worked with birds, rodents and invertebrates, but mostly fish. My PhD work focused on stickleback foraging and now I work in aquaculture, mostly with salmon behaviour.
