Areas of expertise
Biodiversity, Biogeography, Ecology, Marine conservation, Freshwater conservation, Climate change, Sea-lice, Biodiversity informatics, Marine reserves, Marine Protected Areas (MPA)

My interests are in biodiversity, biogeography and ecology, especially in the ocean, with applications in relation to nature conservation, climate change, invasive species, and aquaculture.

I am from Kildare in Ireland. I studied in Galway (BSc Hon. Zoology NUIG) and Cork (PhD UCC), followed by postdoc's at the Marine Biological Association Plymouth, and jointly with the Marine Laboratory Aberdeen and Napier University Edinburgh (where I was based at Poolewe, a remote field station on the west coast). After being a lecturer in Trinity College Dublin for 6 years my group set up a research and consulting company called EcoServe (Ecological Consultancy Services Ltd) of which I was Managing Director. I was Executive Director of the Huntsman Marine Science Centre in St Andrews, New Brunswick, Canada for almost 4 years, and then became a professor at the University of Auckland, New Zealand until joining Nord University in 2020.

I coordinate the following courses:

MSc course Aquaculture and the Environment and associated PhD course

MSc course Biodiversity and Biogeography and associated PhD course

PhD course Topics in Ecology


an interview about the origins of the World Register of Marine species

public lectures about the oceans and need for Marine Reserves and my research journey.


Current international projects:

MPA Europe

MBON Europe

See my Research Group website for information on recent research and tips for graduate students (and things I should also remember) and other web links.

Google Scholar profile for publications.

I post a daily news item to the Facebook page for Marine Reserves.

I manage the email lists MARINE-B (marine biodiversity for the International Association for Biological Oceanography), and Caligus on sea-lice biology and control.
