We are interested in the cell and molecular biology of protozoan parasites. Most of our work is focused on members of the phylum Apicomplexa. Organisms in this group cause a number of important diseases including malaria, severe opportunistic infections associated with AIDS, and fetal and early childhood diseases. We use a broad array of modern genomic, genetic, cell biological and biochemical approaches to understand fundamental parasite biology and use this knowledge to identify and develop targets for intervention.
