Dr. Videlis Nduba -Deputy Director, CRDR

Dr. Videlis Nduba is a Deputy Director in charge of the Center for Respiratory Diseases Research (CRDR).
He has worked at the Institute for over 13 years with his work focusing in TB Research including developing tuberculosis epidemiological capacity to conduct phase II and III TB vaccine trials in adolescents and infants, diagnostics for infant TB, and epidemiology of TB in adolescents. He was a principal investor of a double-blind, randomised, placebo-controlled, dose-finding trial of the novel tuberculosis vaccine AERAS-402) in infants, of which Kenya was one of four countries participating in this trial.

Dr. Nduba has conducted two TB vaccine trials, one in infants and the other in adults that included bio banking protocols and extensive immunology sample collection and processing.

He has also lead a TB drug treatment trial that examined at a novel new treatment- MPaZ for shortening TB treatment from six to four months for drug sensitive TB. This research has included developing extensive networks with the TB treatment program, community networks with TB ambassadors and community health.


Asiko Ongaya

Ms. Asiko is trained as a medical laboratory scientist (Bsc) and Mycobacteriologist (Msc) and currently undertaking a PhD studies in Microbiology. She has seven years of experience in Infectious Disease Research (especially in TB). Her research goals include to new TB diagnostics, TB drug resistance, TB drugs and to understand the protective host response to Mycobacterium tuberculosis (M.tb), especially as compromised by HIV. Ms. Asiko is currently working as Research Officer at the Centre for Respiratory Diseases Research, Kenya Medical Research Institute (KEMRI), involved in various research projects as a Principle Investigator and co-investigator.


Dr. Jane Rahedi Ong’ang’o-Senior Research Officer
