Research Interests

I am a Research Fellow and a Medical Entomologist at the Parasitology Department of the Noguchi Memorial Institute for Medical Research. I hold a PhD in Vector Biology from the Liverpool School of Tropical Medicine, UK. I have extensive experience in Medical Entomology in both field and laboratory techniques. My research interest focuses on vector biology with emphasis on the application of modern methods to address the burden of vector-borne diseases. I am 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. I am also the Focal person for African Network of Vector Resistance (ANVR/WHO/AFRO) in Ghana and currently developed and coordinates the National Insecticide Resistance Monitoring Partnership in Ghana. I am a member of American Society of Tropical Medicine and Hygiene.
