Siddhartha Mahanty, M.D., M.P.H.
Assistant Chief, Clinical Parasitology Section, LPD
The Clinical Parasitology Section is an interdisciplinary group of clinically trained LPD staff members who oversee the clinical research portfolio and provide clinical care, consultations, and training in tropical medicine and parasitology. The overriding goals of this program are
Although the Clinical Parasitology Section has protocols to see patients with any parasitic infection, the overwhelming majority of patients have neurocysticercosis, filarial infections (lymphatic filariasis, onchocerciasis, loiasis, mansonellosis), strongyloidiasis, hookworm infections, ascaraisis, giardiasis, echinococcosis, and leishmaniasis. We occasionally see patients with gnathostomiasis, African trypanosomiasis, Chagas disease, and malaria, among others.

Dr. Mahanty received his M.B.B.S. from the University of New South Wales, Sydney, Australia, and training in internal medicine at the Australian National University, Canberra, Australia. He completed his fellowship in infectious diseases at the University of Oklahoma and Case Western Reserve University and postdoctoral training in parasitology and immunology in the Laboratory of Parasitic Diseases, NIAID. He is board-certified in internal medicine and infectious diseases. He also holds a diploma/certificate in tropical medicine and travelers’ health. He held faculty appointments at McGill University (Centre for Tropical Medicine) and the Centers for Disease Control and Prevention (CDC) in Atlanta before moving to NIH in 2003. Prior to joining the Laboratory of Parasitic Diseases in 2005, he was a staff clinician in the Malaria Vaccine Development Branch (now the Laboratory of Malaria and Vaccinology), where he oversaw the immunological evaluation of malaria vaccines and was principal investigator on several clinical trials. He is the author or co-author of more than 50 publications in the field of parasitology and immunology. In addition to a research interest in parasite, viral, and vaccine immunology, he has extensive clinical experience in tropical medicine and the conduct of research protocols.
