Patrick T K Woo (Edited By) Patrick T K Woo (ptkw) is University Professor Emeritus, University of Guelph, and has been a faculty member since 1974. His research program focused on parasitic flagellates which included those of medical and economic importance. The program had continuous NSERC support for over 40 years, until he closed his laboratory at U of G so he could, with his co-editors, focus on formulating and editing an interdisciplinary book series on 'climate change and fish health'. Patrick's research and travels, sponsored by other agencies (e.g. FAO, United Nations; National University of Singapore; CNPq, Brazil; MEC, Spain; NEC, Cdn.; CIDA, Cdn.; IDRC, Cdn) 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). In addition to publishing papers and review articles in journals and books, Patrick edited a special journal issue and 14 academic books on fish health. He also founded 'The Roy C Anderson Memorial Lecture in Parasitology'. He has also consulted to industry, universities and government agencies.
