About

I am an academic at the University of Derby where I have been employed since 2013. My prior academic career was at Newcastle University, where I was awarded both my degree and my doctorate. Between my degree and my PhD, I spent just short of four years traveling around the world as a research assistant for numerous scientific projects. These included biodiversity index surveys in the Philippines and Malaysia, radio-tracking Sumatran rhinos in Borneo, rehabilitation and management of the endangered black robin in the Chatham Islands, New Zealand and being a game ranger in mainland Africa and Madagascar.

Since completing my PhD, I have published over 100 research articles in peer-reviewed journals in the past 10 years. Currently, in addition to my teaching responsibilities at the University, I am the manager of the Aquatic Research Facility which was funded through my partnership with SeaLife.

I have a strong passion for the importance of public engagement in science as evidenced through my various engagements with schools and public groups at science outreach events. I always aim to regularly disseminate my research findings and conduct this through invitations to academic conferences and specialist seminars.

To date, I have won numerous awards including the Charles Darwin Award lecture from the British Science Association and staff excellence awards at the University of Derby.

I am currently the director of studies for three PhD students, and supervise numerous undergraduate research projects in their final year of study.

Teaching responsibilities

I teach on a wide range of modules throughout years four, five, six and seven, including; Evolution of Life, Molecular Biology, Invertebrates, Rainforests, Deserts and Oceans, Habitat Management, Tropical Marine Biology, and Independent Studies. I also supervise students on their 3rd year Independent Research projects, Masters projects and PhDs.

Research interests

My research interests are broad and our group work on genomics, metabolomics, epidemiology, microbial interactions with hosts, the roles pathogens play in disease causation, immune responses of hosts to specific diseases and ways to manage or mitigate spread of disease (particularly probiotics). My main research focus is coral biology and the use of eDNA to describe the distribution and spread of rare, endangered or invasive species in freshwater ecosystems (see recent publications).

Experience in industry

We offer a microbial analysis service to anyone interested in research or specific pathogen identification. Our particular focus at the moment is with the aquarium industry, zoos and aquariums. We also work on eDNA as a Molecular Consultant with Surescreen and a Marine Advisor for Brindle and Green Ecological Consultancy.

International experience

My work has taken me all over the world to conduct field based research, present lectures and attend or host workshops.
