Overview: Cormac Gahan graduated in 1996 with a PhD in Immunology and Microbiology from University College Cork. He has since published 167 peer-reviewed articles and book chapters in journals including PNAS, Molecular Microbiology, Infection and Immunity, Vaccine and Journal of Bacteriology. His current h-index is 75 on Google Scholar with total career citations of 19276 (Google Scholar). Prof. Gahan led the Infectious Disease programme with Prof. Colin Hill within the APC Microbiome Institute ( http://apc.ucc.ie ) from 2003-2013, lead the Bile Research Group within the APC with Dr. Susan Joyce and now is PI within the APC. His research interests focus upon host-microbe signalling in the gut mediated via microbial bile acid metabolism (see Joyce et al., PNAS, 2014 - 252 citations; Jones et al., PNAS, 2008 - 510 citations; Begley et al., 2005 - 1178 citations). Prof. Gahan also has a long history of research work on the foodborne pathogen Listeria monocytogenes (in collaboration with Prof. Colin Hill) resulting in a number of key papers in the area (for example see Corr et al., PNAS, 2007 - 722 citations). Recent work has also examined the use of live L. monocytogenes and L. lactis vectors as gene and protein delivery platforms for novel vaccination and therapeutic approaches. This work has been carried out in collaboration with Prof. Mark Tangney at the Cork Cancer Research Centre and Prof. Brendan Griffin in the School of Pharmacy, UCC. In addition to his role as a funded researcher and PI in the APC he is funded by further grants from Science Foundation Ireland, the Health Research Board and the EU (FP7 and H2020). Prof. Gahan is currently on the Editorial Board of the Journal of Pathogens and Microbiome and was on the editorial board of Journal of Applied Microbiology & Letters in Applied Microbiology from 2004-2010 and Applied and Environmental Microbiology (from 2012-2018). He is a regular reviewer for numerous journals (including PNAS, Plos One, Microbiology, J. Bacteriol., AEM). Prof. Gahan directed the SFI funded UREKA summer school programme entitled Microbe-Host Interactions that provided laboratory training for 84 undergraduate students from 2006-2011.

Research Interests

Research OverviewMy research group is dedicated to understanding the molecular interactions between bacteria and the host in the gastrointestinal tract. Our work has examined the pathogenesis of specific gut pathogens (in particular Listeria monocytogenes and Clostridium difficile) as well as the specific interactions that occur between gut commensals and the host organism. A complete understanding of the mechanisms governing host-pathogen interactions in the GI tract can be used to inform vaccine or DNA delivery strategies, to combat infections or to exploit the unique properties of these organisms as live vectors for the delivery of novel therapeutics. For example in collaboration with Dr. Mark Tangney at the Cork Cancer Research Centre we have recently exploited attenuated L. monocytogenes as a gene delivery vehicle for targeting tumour cells (van Pijkeren et al, 2010, Human Gene Therapy). In addition, benign L. lactis bacteria can be used to express a protein from L. monocytogenes that improves the ability of the organism to act as a vaccine delivery vector (in collaboration with Dr. Brendan Griffin; Bahey-el-din et al., 2008, Vaccine).
L. monocytogenes shares much in common with normal harmless bacteria that reside as commensals in the human GI tract. We have utilized culture-independent approaches (metagenomics) to examine one such activity (bile salt hydrolase (BSH)) that is abundant throughout the entire population of organisms in the GI tract (Jones et al., 2008, Proceedings of the National Academy of Sciences). More recent work in my group (with Dr. Susan Joyce) has demonstrated the significant impact exerted by bacterial BSH activity in the gut (Joyce et al. 2014, Proceedings of the National Academy of Sciences). The work demonstrates the potential for gut bacteria to significantly alter host physiological parameters (including immune function, lipid metabolism and circadian rhythm) by coordinating changes to host bile acid profiles. Ongoing work in our Bile Research Group is further examining the impact of microbially-altered bile acid profiles upon disease states using appropriate models.

Outreach Activities

	Description
	Outreach activities through the Alimentary Pharmabiotic Centre (http://apc.ucc.ie) include: School visits, School lectures (leaving cert), UREKA Microbe-Host Interactions Site
	There was significant publicity for our recent paper in PNAS (2014) concerning obesity management via the microbiota. The story featured on numerous newspapers and online science publications and blogs. These included BBC News (website), RTE News (website), Irish Examiner (print and web), The Irish Times (print and web). Selected Links: http://www.bbc.com/news/world-europe-27294763 http://www.irishexaminer.com/ireland/gut-bacteria-research-could-help-regulate-weight-and-cholestero...
	Dr Gahan was lead investigator (with Dr. Sally Cudmore, APC) in funding of the UREKA Microbe-Host Interactions (MHI) summer undergraduate research school from 2006-2011 This resulted in numerous outreach events and publicity in the popular press
