Short Biography
Dr. Gebrekrstos Negash Gebru is a senior epidemiologist with over 17 years of progressive public health leadership and operational public health research experience across sub-Saharan Africa, including Liberia, Kenya, Ghana, Sierra Leone, and Ethiopia. He has held prominent technical and advisory roles at the World Health Organization (WHO), the U.S. Centers for Disease Control and Prevention (CDC), and AFENET, contributing to major global health security priorities and disease control programs. Dr. Gebru is internationally recognized for his expertise in Field Epidemiology Training Programs (FETPs), having spent more than a decade as a mentor, academic coordinator, and Resident Advisor. He led the successful global accreditation of the Sierra Leone FETP-Intermediate, positioning it among the first accredited programs worldwide. He has taught, supervised, and mentored more than 400 public health professionals, including 103 advanced epidemiology trainees, significantly enhancing national public health workforce capacity.
His technical work includes curriculum design, training systems development, strengthening surveillance, scientific writing, and operational research. He has led and contributed to responses to major public health emergencies, such as the Ebola outbreak in Liberia, wild poliovirus in Kenya, meningitis in Ghana, and various outbreaks in Sierra Leone, including Lassa fever, anthrax, COVID-19, and Mpox. An accomplished scholar and program leader, Dr. Gebru has secured and managed competitive grants, including support from the Bill & Melinda Gates Foundation (BMGF), Vital Strategies, and multiple U.S. CDC funding sources. He currently serves as the Principal Investigator for the U.S. CDC/AFENET five-year Global Health Security Agenda (GHSA) Cooperative Agreement (2021–2025), under which Sierra Leone has trained 126 field epidemiologists at advanced and intermediate levels and 323 frontline public health workers.
Dr. Gebru’s work has shaped national training systems, advanced surveillance innovations, and informed policy development across several African nations. His scholarly contributions, leadership in research and workforce development, and impact on global health security underscore his national and international stature. He also serves on the Editorial Advisory Board of the East African Journal of Health Sciences, Mekelle University, Ethiopia.
