Dr Rachael Antwis

Lecturer in Global Ecology and Conservation

Office Times

Monday 1-3pm


After completing my PhD looking at how environmental variables shape the bacterial communities of amphibians, I conducted a Postdoctoral Research Fellowship at North-West University in South Africa to look more closely at interactions between bacterial communities of amphibian hosts, and the hyper-virulent chytrid fungus. Following that, I took up my current position as a Lecturer in Global Ecology and Conservation at the University of Salford.

Field Biology

Research Interests

I'm primarily interested in interactions between host skin microbiomes of amphibians and the highly virulent chytrid fungus pathogen. I'm also interested in genetic and environmental variables that influence composition of the skin microbiome, and how to artifically augment amphibian microbiomes to increase resistance to infectious diseases. I use both field and experimental (in vitro and in vivo) study systems for this research, and work in collaboration with the University of Manchester, Institute of Zoology (Zoological Society of London), and North-West University in South Africa.
