Her career to date has also been characterized by close collaboration and integration with multiple clinical groups worldwide. She has extensive experience in constructing and using ‘big data’, particularly genome wide association studies and candidate genes data including identification of variants or markers associated with the disease of interest and application of next generation sequencing in the clinical genetics setting. She have served as a co-investigator on over 10 externally-funded grants in clinical trials, TB vaccine trials, disease surveillance, Infectious diseases, including Malaria, HIV/AIDS, sickle cell, emerging and re-emerging Infections.

Dr. Ndila is a member of several Data and Safety Monitoring Board (DSMB) responsible for reviewing epidemiology aspects. Her main research focus is now on genetic susceptibility to tuberculosis, specifically the genomics of resistance and how genetic variation in both humans and the tuberculosis pathogen influence TB severity. Her research has built-in links between TB control boards and local TB community networks including community networks with relevant TB actors and community health workers. She is has also been involved in setting up a CRDR-clinical trial annex at the coastal part of Kenya.
