Vector Ecology and Environment

Our research interests include anything from ecology to molecular biology of medically important arthropods, particularly mosquitoes that transmit pathogens such as malaria parasites and dengue virus in Africa and Asia. We are also interested in their relationships with environmental variables and development of environmentally friendly vector control tools.

Activities

Currently, we are studying the population genetic structures of Aedes aegypti population in Africa. Our study has revealed that mosquito populations in dengue endemic areas exhibit distinct the genetic patterns. We are also studying the genetic structures of the Aedes albopictus populations that were recently introduced in Republic of Mozambique and the Democratic Republic of Congo. This research aims to reveal their origins and introduction pathways, and to understand the dynamics of urban Aedes population.
For reducing malaria risk, we are evaluating the effectiveness of new insecticides and vector control tools in Kenya and Malawi. We are also developing malaria and dengue outbreak prediction models incorporating climate and vector components.
In Kenya, we are conducting longitudinal studies on the intermediate host snails of Schistosomiasis to identify ecological factors influencing their seasonal population dynamics and infection rates.
