Dr Michael Sweet
Position: Lecturer in Invertebrate Biology
College: College of Life & Natural Sciences
Subject area: Biological Sciences
Research Centre: Environmental Sustainability Research Centre
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 48 research articles in peer reviewed journals in the past 6 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 four PhD students and two masters, and supervise numerous undergraduate research projects in their final year of study.
I'm currently teaching on a wide range of modules throughout years 4,5,6 and 7. Modules include; Evolution of Life, Ecosystems, Molecular Biology, Rainforests, Deserts and Oceans, Habitat Management, Tropical Marine Biology, Biology in Practice and Ecological Consultancy. I also supervise students on their 3rd year Independent Research projects, Masters projects and PhDs.
Current Roles, Responsibilities & Skills
- Experience with molecular screening techniques and immune-histology including; Primer design, PCR, qPCR of specific genes and microbial pathogens, DGGE, TRFLP, FISH, cloning and culture techniques (inc single cell isolates), microsatellites, 454 pyro-sequencing, illumina RNA seq, ion torrent, immuno-histological stains (Mason-Fontana, Nigrosin, Silver Staining, Apoptosis Assays)
- Experience with analysis programs including; PRIMER, R, SPSS, Minitab, GeniousPro
- Co-supervisor for PhD, master and undergraduate thesis projects
- Lecturer on modules and field courses for undergraduates
- Manuscript Reviewer for Coral Reefs, PLOS one, PEERJ, Marine Biology and many more
- Consultant for the marine laboratory – Korallion Laboratory, Maldives - www.korallionlab.com
- Consultant for a commercial company called Surescreen on molecular techniques - www.surescreen.com
- Tropical Marine Expert and Advisor for Brindle and Green Ecological Consultancy
- Member of the Coral Aquarist Research Network
My Major Research Interests are in 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. My main focus is marine biology, and in particular I focus on coral reefs and tropical oceans. I do, however, also work with nanoparticles and eDNA.

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.
My work has taken me all over the world to conduct field based research, present lectures and attend or host workshops.
My research has recieved considerable press coverage.
In particular, articles on the discovery of skin cancer in wild fish were published in New Scientist, LA Time, Science Now, Scientific America, Nature Reviews Cancer to name a few.
