BSc (Hons) Biology

MRes Animal behaviour

PhD Laboratory animal welfare

I am a trained mental health first aider.

My research involves a combination of behavioural assessment, with statistical modelling to investigate problem behaviours in laying hens, though I have previously also worked on rhesus macaques, rats and pigs. More broadly, my interests lie in both the mechanisms of animal behaviour and in exploring ways in which behaviour can be measured and used as an indicator of welfare. I have recently developed an interest in invertebrate welfare, and would love to explore this further in the future.
