Short Biography

Samuel Kweku Dadzie, PhD is a Research Fellow and a medical entomologist at the Parasitology Department of the Noguchi Memorial Institute for Medical Research. He holds a PhD in Vector Biology from the Liverpool School of Tropical Medicine, UK.

 He has extensive experience in medical entomology in both field and laboratory techniques. His research interest focuses on vector biology with emphasis on the application of modern methods to address the burden of vector-borne diseases.

 Dr. Dadzie is a member of several committees in Ghana including the Malaria Vector Control Oversight Committee of the Ghana National Malaria Control Programme, Intra-country Advisory Committee on Neglected Tropical Diseases, Technical Advisory Committee of Zoomlion Nationwide Mosquito Control Programme among others. He is the Focal person for African Network of Vector Resistance (ANVR/WHO/AFRO) in Ghana.  He recently developed the National Insecticide Resistance Monitoring Partnership in Ghana and currently the coordinator. He is also a member of American Society of Tropical Medicine and Hygiene.

Administrative Role:

Coordinator of the field and laboratory components of entomology projects in the Department. He also provides staff training on basic entomological techniques.

Research Interests:

Vector biology with emphasis on the application of modern methods to address the burden of vector-borne diseases including aspects on vector bionomics, molecular and population genetics and insecticide resistance.
