Dr Chloe Heys


School of Health, Science and Wellbeing

I graduated from the University of Liverpool in 2012 with a degree in Zoology, before continuing my education with an MRes in Advanced Biological Sciences at the University of Liverpool, graduating in 2013. I continued my time here studying for a PhD in Zoology, under the supervision of Dr Zenobia Lewis and Dr Alistair Darby. I then moved onto the University of Glasgow to fulfil a postdoctoral researcher position within the Llewellyn Lab group, before joining Staffordshire University as a Lecturer in Microbiology in 2020.

Research interests

I am fundamentally interested in host-microbiome interactions, with a particular focus on the role of the gut microbiota on driving the evolution of behaviours in animals. My PhD focussed on the relationship between gut microbiota and animal behaviour in various species of Drosophila with varying ecologies. I use a multi-faceted approach, combining behavioural trials and observations with microbiological and molecular techniques, to test a number of ecological predictions. I have worked with Drosophila in both laboratory and field settings for over eight years, and I have a wealth of experience in conducting large-scale mating experiments and microbiological assays. I extended these techniques when transitioning from studying invertebrates to vertebrates, with my postdoctoral research examining the role of the gut microbiota in mediating health, physiology and behaviour of Atlantic salmon, Salmo salar. Using aquarium facilities at the University of Glasgow and an experimental river system at the Marine Institute in Ireland, I am primarily investigating the role of the gut microbiota in overwintering behaviour, or ‘torpor’, in salmon, but I am also involved in several other projects.

I am also the Principal Investigator on several projects funded by GCRF and others, that investigate the illegal trade of parrots within Indonesia. This project first began through the unique collaboration of international academics, NGOs and policy makers to develop a framework for exploring the effect that the illegal wildlife trade has on bird species (with a particular focus on parrots and raptors) and identifying new methods to reduce this impact. Since then, we have been working closely with registered captive breeding centres and in-country academics and other specialists, to identify how the global COVID-19 pandemic has affected this trade, through a widespread move to online platforms rather than traditional bird markets. We are using a highly interdisciplinary approach–combining disciplines such as zoology, economics, psychology and sociology, in order to achieve this goal.
