Dr. Alex Rosenberg is a trained molecular microbiologist and parasitologist. His research program focused on the interaction of the apicomplexan intracellular parasite Toxoplasma gondii and its mammalian host. This fascinating microorganism is able to invade any nucleated cell, block phagosome acidification, inhibit interferon response, prevent cell death, and grow rapidly inside the parasitophorous vacuole. Current research covers many topics including the cell biology of infection, innate immune responses, and epigenetic modifications driven by Toxoplasma secreted effectors.
