Chief, Malaria Functional Genomics Section

Major Areas of Research

  • Plasmodium genetics and genomics
  • Host-parasite interaction and molecular signaling
  • Antimalarial drug development and mechanisms of drug resistance

Our laboratory develops and uses genetic and genomic approaches to study host-malaria parasite interaction and molecular mechanisms of the interaction using the rodent malaria parasite Plasmodium yoelii as a model. We have characterized large numbers of microsatellites and single nucleotide polymorphisms (SNPs) from several P. yoelii parasites and performed various genetic crosses to identify parasite genes linked to parasite development, virulence, and drug resistance. We are studying host immune signaling pathways in response to parasite infections, focusing on innate signaling and regulation of type I interferon production and inflammatory responses after malaria infection.

We are also interested in screening and development of new antimalarial drugs, particularly compounds that can block malaria transmission.

Dr. Su received his Ph.D. in parasitology from the University of Georgia in 1990. He joined the NIAID Laboratory of Parasitic Diseases in 1992 and became an investigator in the Laboratory of Malaria and Vector Research in 2001 and a senior investigator in 2006.
