John is a founding member and current Director of UCC's Quercus Talented Students'​Programme. He is the Chair of the Green Campus Forum at UCC which has received many awards in recognition of its efforts to promote the Green Agenda at UCC, including the first green flag ever awarded to a university. He was a finalist in the Green Gown Leadership Awards (UK & Ireland) in 2017 for his leadership of sustainability objectives at UCC. John has been a judge for the prestigious UNESCO-L’Oreal-Royal Society Women Science Scholarship, and for the BT Young Scientist Competition, for many years. 

He was previously Head of School of Biological, Earth and Environmental Sciences at UCC, where he holds the Chair in Zoology. He is also a former Vice Head of College of Science, Engineering and Food Science, a role he fulfilled for five years. He has held academic posts in Cardiff, Maine and has delivered lectures widely across Europe and North America.

 

Research Interests

John is an ecologist with an interest in birds, particularly swans and dippers, and also in forest ecology, having led a large number of research projects in these fields. 

John has published more than 200 refereed research articles, 8 books, and 16 book chapters in internationally published books. He has presented over 150 research presentations nationally and internationally and published one monograph and a number refereed technical reports for translation of research to industry and other stakeholders.He has been awarded over 9 million euro for research, teaching and conferences. During his career he has supervised 25 Masters research projects and 31 PhD projects to completion. He recently completed a 6 year term as executive Editor of the international journal Bird Study, during which time he increased its ranking significantly and was awarded a prize for journal design and publishing.John is the joint leader of the Centre of Excellence in Ornithology at UCC which is now recognized internationally and was responsible for developing the Centre of Excellence in Ecotoxicology at the Environmental Research Institute, UCC, where he is joint strategic research coordinator.

John is dedicated to transferring research from the field, lab and bench to class and industry. John has completed over 50 research projects (many collaborators, nationals and international) since 1989. He directs a range of projects on forest biodiversity  (http://www.ucc.ie/en/planforbio/) forests and water (http://www.ucc.ie/en/forestecology), biotoxins and avian ecology.
