Research Summary

Our lab is interested in the molecular events that enable apicomplexan parasites to remain widespread and deadly infectious agents. We study many important human pathogens, including Toxoplasma gondii, to model features conserved throughout the phylum. We seek to expand our understanding of eukaryotic diversity and identify specific features that can be targeted to treat parasite infections.
