Program Description

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.
