Dr Owen Nkoka

  • Research Associate Cohort Manager (Public Health)

Biography

I am a Research Associate in the Department of Public Health within the Institute of Health and Wellbeing, seconded as a Research Manager/Epidemiologist at The Malawi Epidemiology and Intervention Research Unit (MEIRU). I am currently working on a Wellcome Trust-funded project, Healthy Lives Malawi (HLM): An intergenerational chronic conditions cohort. I have a BSc in Environmental Health from The University of Malawi, an MSc and a PhD in Public Health from Taipei Medical University. My PhD assessed the effects of malaria interventions on child health outcomes. I am a certified project manager for development professionals and an associate of the Chartered Management Institute.

Previously, I worked with several international organisations such as World Vision to implement public health programs focusing on maternal and child health. I also worked as a Research assistant at Taipei Medical University on projects covering maternal and child health and health services culminating in several publications in peer-reviewed journals.

My current research focuses on demographic surveillance systems and long-term conditions.
