Patrick is University Professor Emeritus at U of G and has been a faculty member since 1974. His research program was on parasitic flagellates which include those of medical and economic importance. The program had continuous NSERC support (>40 years) until he decided to close his laboratory at U of G. This was so he could, with his co-editors focus on formulating and editing an interdisciplinary 3-book set on 'climate change and fish health'. His research and travels, sponsored by other agencies (e.g. FAO, United Nations; NUS, Singapore; CNPq, Brazil; MEC, Spain; NEC, Cdn.; CIDA, Cdn.; IDRC, Cdn) had allowed him to work with colleagues in Asia, Africa, Europe and the Americas (e.g. ‘determine the toxicity of cadmium on tilapia and its effects on immune response’ in Singapore; ‘develop and evaluate diagnostic techniques for human trypanosomiasis’ in E & W Africa; ‘adapt an in vitro method to study fish innate immunity’ in Spain).
He had hosted 11 Visiting Scientists and was research supervisor to 12 Post-docs, 11 PhD, 18 MSc & >10 BSc students. Aside from publishing papers and review articles in journals and books, he also edited a ‘special’ journal issue and 13 academic books on fish health; e.g. the 3-book set on ‘climate change and fish health’ was published in 2023 by CABI, UK..
He was founder and organizer of 'The Roy C Anderson Memorial Lecture in Parasitology'; eminent scientists and scholars including a Nobel Laureate had accepted his invitations, presented public lectures at U of G and interacted with students staff and faculty. U of G Senate elected him 'University Professor Emeritus' and it was conferred at convocation by the Honorable Lincoln M Alexander, Chancellor.
