Gary J. Weil, MD

Health, Tropical Diseases, Death to Onchocerciassis and Lymphatic Filariasis

Dr. Gary Weil is conducting research into tropical diseases in Africa that has changed global public health policy. Dr. Weil is director of the Death to Onchocerciasis and Lymphatic Filariasis (DOLF) Project. He’s also a professor in the department of infectious diseases at Washington University.

Dr. Weil’s work spans Africa, from Cote d’Ivoire to the Democratic Republic of Congo. Onchocerciasis, also known as River Blindness, and lymphatic filariasis, better known as elephantiasis, are major public health challenges in the developing world that afflict hundreds of millions of people and can lead to physical disabilities. The DOLF Project develops and evaluates diagnostic tests for parasitic infections.

Dr. Weil and the DOLF Project’s work has led to changes in World Health Organization policies related to elimination of onchocerciasis and lymphatic filariasis in Africa. His work is funded through the Bill and Melinda Gates Foundation and he has won the Anne Maurer-Cecchini Award, which recognizes outstanding epidemiological or clinical research on neglected tropical diseases.
