M. Kariuki Njenga
Dr. Kariuki Njenga is Professor at the Washington State University Paul G. Allen School for Global Animal Health, and the Country Director of the WSU Global Health Program - Kenya. He holds a Bachelor of Veterinary Medicine and Master of Science degrees from the University of Nairobi, Kenya, and a PhD from the Pennsylvania State University, US. Dr. Njenga obtained 5 years of post-doctoral training at the Mayo Clinic in Rochester, Minnesota, US. His research training is in virology and immunology but he has gained extensive experience in conducting basic and field studies in infectious diseases over the past 16 years, resulting in publication of more than 170 peer-reviewed papers on the subject. Between 2004-2011 (8 years), Dr. Njenga served as Laboratory Director of the CDC in Kenya, first to establish and equip the laboratories and later to lead diagnostic testing for outbreaks in the horn of Africa and East Africa (Kenya, Somalia, Sudan, Ethiopia, Tanzania, Uganda, and Rwanda) for disease such as Rift Valley fever, Avian influenza, Hepatitis E, Leptospirosis, and anthrax. At CDC, Dr Njenga also worked with CDC epidemiologists to establish a human population-based syndromic surveillance for acute febrile illness, jaundice, respiratory illness and diarrheal in among urban and rural populations.
Between 2011 and 2014, Dr. Njenga served as head of the One Health Program at CDC-Kenya and the Kenya Medical Research Institute (KEMRI), focusing on establishing a multisectoral OH approach (setting up policies, institutions, and research) that enhanced Kenya’s efforts in preventing and controlling zoonotic diseases. For One Health research, he focused on conducting systematic burden of disease studies on priority episodic and endemic zoonotic diseases in the East Africa region, and studies at the animal-human-environment interface in order to elucidate the mechanisms of animal-to-human transmission. In addition, he was instrumental in developing a linked human-animal population based syndromic surveillance platform that investigated the nutritional, economic, and zoonotic interactions between rural sub-Saharan people and their livestock.
My desire to become a microbiologist and research scientist became obvious in my 2nd year of Veterinary School, and since then I have stayed the course. The pursuit of this path was inspired by two things; my early knowledge of the simplicity of a virus life cycle and its ability to harness the replication cycle of eukaryotic cells to propagate itself and cause disease, and a desire to do research, publish, and be cited by others. Apart from research, I love playing golf and lawn tennis, and traveling.
