I joined the Human Toxicology Program at the University of Iowa in 2007.

I transferred to UI from New Jersey. It seems I made the right decision. In 2007, I became a Tox PhD student in the brand new program. As a guy who plays with “toxicants,” I do work on finding mechanisms and pathways in which the toxicants affect human body rather than post–treat the pollution, which I did before.
