Research summary
AI-generated

William J. Sullivan studies Toxoplasma gondii, a single-celled parasite that infects humans and animals and can persist as dormant tissue cysts. His research focuses on how this parasite switches between growth stages, manages DNA damage and repair, and controls its genes through histone (DNA-packaging protein) modifications, with additional work aimed at finding new drugs to treat infection. Some recent projects also extend to other parasites and to cancer biology models.

Publication activity was higher in the late 2010s (around 11-19 papers per year) and has settled to a lower, roughly steady rate of about 5 per year in the last five years.
