SUMMARY

Prof. Jackson N. Ombui is a Professor of Veterinary Public Health with a university teaching experience spanning over 34 years. I hold a Bachelor of Veterinary Medicine, as well as Masters and PhD degrees in Veterinary Public Health from the University of Nairobi. I am registered with the Kenya Veterinary Board and a member of the Kenya Veterinary Association.  I started my teaching career at the University of Nairobi where I rose through the ranks to the position of Professor. I am currently an Adjunct Professor of Veterinary Public Health at Egerton University, a position I have held since October 2019. During my teaching career, I have also provided teaching services to other Universities in Kenya including Jomo Kenyatta University of Agriculture and Technology and United States International University-Africa.  I have published over 45 articles in refereed journals and supervised a number of Masters and PhD students in addition to examining theses for a large number of postgraduate students from the University of Nairobi, Kenyatta University, Jomo Kenyatta University of Agriculture and Technology and Egerton University. I have previously consulted with FAO-Somalia, AU-IBAR, Save the Children and Land‘O’Lakes Inc. I have also served as a member and chair of the Kenya Bureau of Standards technical committee on food additives and contaminants, and as an AU-IBAR expert on formulation of CODEX food hygiene standards. My  research interests include Food safety, food borne disease, Zoonoses, Antimicrobial resistance and Molecular Epidemiology
