Postdoctoral Fellow, Eco-epidemiologist (modelling dynamic disease systems)
Office Phone: +254727671796
Dr. John Gachohi is a Post-Doctoral Fellow at the Washington State University Global Health Program - Kenya. He holds a Bachelor of Veterinary Medicine and Master of Science (MSc) and PhD degrees in Epidemiology from the University of Nairobi, Kenya. His initial MSc research training is in classic, spatial and participatory epidemiology, but he gained extensive experience in infectious disease modelling (individual-based and mathematical) during his PhD training. Over the past 15 years, he has been involved in field studies in infectious diseases resulting in publication of twenty peer-reviewed papers. These studies constituted diseases such as African Animal Trypanosomiasis, East Coast Fever, Anaplasmosis, Babesiosis, Theirelia mutans infection, pig-mediated zoonoses and other pig parasites, Peste-des petits ruminants (PPR) and Rift Valley fever and currently anthrax and MERSCov in camels. Since 2014, John has been a faculty staff in the School of Public Heath, Jomo Kenyatta University of Agriculture and Technology (JKUAT) teaching the following postgraduate course work units: Epidemiology, Biostatistics and Demography, Research Methodology, Health Programmes and Health Research and Computer Applications in Health Research. In addition, he teaches the following undergraduate course units: Biostatistics and Research Methodology, Food Inspection and Hygiene, Environmental Health and Health Economics.
While I did not plan to become a veterinarian, pursuing epidemiologic research was deliberate. I have strong interests in understanding the entire (multilevel-hierarchical) causative chain in infectious and non-infectious disease dynamics for better health - the chain extends from the highest level - the social and structural community-specific, physical landscape and environmental influences; then risk factor epidemiology on behaviors and exposures at the individual level (level 2) and molecular epidemiology on biological mechanisms (level 1). I fully recognize that such a perspective must allow for greater methodological pluralism that includes (i) classical quantitative epidemiology that embraces simulation modeling, risk analyses, spatial epidemiology, etc and (ii) qualitative epidemiology, all in systems- thinking approach. More was to come when an opportunity came to join “academic” epidemiology in the School of Public Health, Jomo Kenyatta University of Agriculture and Technology (JKUAT) in the outskirts of Nairobi, Kenya. I was then and continue to be enthusiastic about being able to conduct research and teach epidemiology in a way that meaningfully contributes to the growth of the discipline. I have progressively grown in the hands of seniors while at the same time had the privilege of working to help my juniors improve in their understanding and skill, recognizing that that there is both a learner and a teacher in me. Outside the epidemiology lab and class, I find music, reading biographies and travelling satisfying my heart.
