Recent Projects

Assessing the progress towards rabies elimination from Pemba Island, Tanzania

Rabies is a deadly disease endemic in dog populations across Africa. Although rabies can be eliminated through mass dog vaccination, there has been little investment in dog vaccination in Africa …

Engaging pastoralists in controlling malaria mosquitoes in their communities

The project is aimed at applying pastoralists’ knowledge to find water bodies during the dry season and accurately identify aquatic habitats that can be treated with larvicide pyriproxyfen (PPF) to …


The group focuses primarily on ecology and transmission of infectious diseases. The work also includes development and testing of surveillance and control measures. Key areas of work include: a) Mosquito Ecology and Control, b) Water, Sanitation and Hygiene Research, c) Neglected Tropical Infectious Diseases and Zoonoses, and d) Advanced Statistics, Mathematical Modeling, Health Geographics and Social Innovations.

In recent years, major activities have included Research on Ecology of disease-transmitting mosquitoes with special focus on malaria and now expanding to other mosquito-borne diseases including Dengue, Filariasis and Zika. We also have a large body of work on on novel and improved vector control and surveillance tools. IHI is now a WHO collaborating site for product evaluation (malaria vector control). We have developed number of tools which are in wide use for measuring metrics of mosquito behaviour and densities and evaluating the impact of vector control Interventions.
