The Aquatic Animal Health Group, headed by Professor Sarah Culloty, specialises in ecological parasitology and immunology. Much of the research produced by this group focuses on diseases of commercially significant bivalve shellfish (oysters, clams, mussels, scallops, cockles). However, some work is also ongoing on other groups (crabs, polychaetes, gastropods, tunicates), investigating general aspects of invertebrate biology. The Group is heavily involved in collaborative research with numerous active partners across Europe and further afield. Recent research interests include looking at the impact of potential climate change drivers on disease development in the marine environment.

Group Profiles

Prof Sarah Culloty

Sarah is the Principle Investigator for the Aquatic Animal Health Group. She is also Director of the Environmental Research Institute at UCC and Head of the College of Science, Engineering and Food Science. A Zoologist and Marine Biologist in the School of Biological, Earth and Environmental Sciences (BEES), her main area of research is in ecological parasitology with a particular focus on molluscan diseases. The focus of her research centres on pathogen (macroparasites, protozoa, bacteria and viruses) life cycles, epidemiology, diagnostics and approaches to reducing impacts of disease. Recent research looks at the impact of potential climate change drivers on disease development in the marine environment. Sarah has a h-index of 29 and an i10-index of 63 with a total of 206 scientific publications (2818 citations). While at UCC, Sarah has won 20 research grants totalling over €5 million.

Dr Sharon Lynch

Sharon is a Research Fellow and Co-PI of the Aquatic Animal Health Group.  Sharon’s research interests and expertise are in ecoparasitology, invertebrate pathology, aquatic animal health, biotherapeutics and photodynamic therapies.  A primary focus of Sharon’s research is assessing the performance of shellfish species and their pathogens in a changing marine environment, assessing the impacts of environmental parameters associated with meteorological extremes, pathogen range/host expansion and evolution (genetic and morphology).  Sharon has a h-index of 15 and an i10-index of 20 with a total of 50 scientific publications (878 citations) and collaborations with over fifty institutes.

Gary Kett 

Gary received a BSc (Hons) in Zoology from UCC in 2015. His research interests began with marine mammals and survey data collection at sea. He has worked with bottlenose dolphin research centres in Ireland and abroad and spent time carrying out at-sea surveys of marine mammals, fish and shellfish for the Marine Institute. He returned to UCC in 2017 to complete a Masters through Research (MRes) which was funded by VIVALDI – an EU Horizon 2020 project aimed at preventing and mitigating farmed bivalve diseases. After completing the Masters, Gary was interested in continuing his research and advanced to PhD level in order to continue investigating the role of sunlight (UV radiation) in aquatic animal health and host-pathogen dynamics. This continuation was facilitated through funding from the EU Interreg projects BLUEFISH and COCKLES. Currently in his third year of his PhD, he loves the diversity in his research, which includes fieldwork, lab diagnostics and computer-based analysis. Gary is especially interested in science communications and outreach and has during his PhD has taken part in 14 conferences and 3 public outreach events.
