Research Interests

The principle area of my research has been the study of protozoan parasites and how they interact with their respective hosts. Currently, I have research projects underway to investigate several aspects of the liver stage of Plasmodial parasites. The liver has been demonstrated to be a target for the host's immune response, yet the exact antigenic targets have not been clearly defined. I am interested in identifying antigens that may be respon-sible for the induction of a protective immune response. Additionally, the mechanisms that are utilized to protect the host are being studied. Both Plasmodium yoelii and Plasmodium falciparum are being used to study these molecular and immunological events that accompany infection of hepatocytes.
