Dr. David Diemert is Associate Professor in the Departments of Medicine (primary) and Microbiology, Immunology, and Tropical Medicine (secondary) at GW. Additionally, he is the Clinical Director of GW Vaccine Research Unit (GW VRUS), which is a collaboration between the School of Medicine and Health Sciences and GW MFA. At GW, Dr. Diemert is also the co-Director of the Immunology, Hematology, Inflammation and Infection block of the preclinical medical student curriculum. Prior to joining GW, Dr. Diemert worked for four years at the Malaria Vaccine Development Branch of the National Institute of Allergy and Infectious Diseases, where he was responsible for conducting clinical trials of novel malaria vaccines, both in the United States and in Mali, West Africa. Dr. Diemert earned his medical degree from the University of Alberta in Edmonton, Canada, and completed residency and fellowship training at McGill University in Montreal. He is a Fellow of the Royal College of Physicians (Canada) with certification in the specialties of internal medicine, infectious diseases and medical microbiology. Additionally, he received training in clinical tropical medicine through the University of Alabama at Birmingham’s Gorgas Course in Lima, Peru.
Dr. Diemert’s research is focused on conducting clinical trials to develop new vaccines for neglected tropical diseases and viral infections in the United States, Brazil, and Africa. He has served as the Principal Investigator on multiple clinical trials of hookworm, schistosomiasis, malaria, flavivirus and HIV vaccines. More recently, he has developed a controlled infection model at GW to test the efficacy of investigational human hookworm vaccines. He currently has funding from NIAID/NIH, US Department of Defense, the European Commission, and the International AIDS Vaccine Initiative (IAVI).
Dr. Diemert’s work in Brazil has involved establishing a clinical trial site in partnership with the Fundação Oswaldo Cruz (FIOCRUZ), which has included establishing a clinic in a rural area of Brazil, assembling and training a Brazilian clinical trials team, establishing quality laboratory facilities at the field site, conducting preparatory studies of helminth epidemiology and immunology, and overseeing several Phase 1 and 2 trials of investigational vaccines.
