Research Interests

As part of the Eukaryotic Pathogens Innovation Center (EPIC), my lab is interested in the intestinal parasite Entamoeba histolytica, which causes amoebic dysentery in ~90 million people each year. E. histolytica is ingested in its cyst form in contaminated food and water. In the small intestine it converts to its amoeba form and then colonizes the large intestine, where is can cause dysentery or establish an asymptomatic infection. We are studying how E. histolytica adapts to and thrives in the glucose-poor environment of the large intestine where it colonizes. We have recently established robust, reproducible cyst formation in laboratory culture and are studying how this process is regulated directly in the human pathogen.
