Akram Da'darah, M.Sc. Ph.D. is a Research Assistant Professor at the Cummings School of Veterinary Medicine who joined the Molecular Helminthology Laboratory in 2010. His main research focuses on Host-Parasite interaction in order to understand how schistosome parasites are able to survive in the host for several years. The overall objective of his research is to identify novel candidates that can be used as drug targets and/or vaccine candidates. Prior to joining Tufts University, Akram has worked at the Department of Immunology and Infectious Diseases/Harvard School of Public Health for twelve years as a post-doctoral fellow, a research associate and a scientist. He has extensive experience in studying schistosome parasites.

He received his Ph.D. in Molecular and Biochemical Parasitology in 1997 from Bernhard Nocht Institute for Tropical Medicine/Hamburg University, Germany. His Ph.D. research focused on polyamine metabolic pathway as a drug target for human parasitic diseases. He also obtained a Master's degree in cytogenetics.

General Research Interests

  • Molecular and Biochemical Parasitology
  • Drug research and development: For parasitic diseases
  • Immune regulation and vaccine development.

Selected Research Projects

  1. Host-Parasite interaction. This project investigates the interactions between schistosome parasites and their host. This will enhance our understanding of the mechanism(s) of the parasites survival in the host for several years, as well as allows us to identify and evaluate novel drug targets for schistosomiasis.
  2. Vaccine development for schistosomiasis. This project will evaluate several novel surface parasites proteins as vaccine candidates against schistosome infections.
