Patrick obtained a B.S. in Chemistry from the Rochester Institute of Technology in 1996 and a Ph.D. in Organic Chemistry in 2001 from the University of Pennsylvania. Following completion of his Ph.D., he began his career at Pharmacia in the Neuroscience chemistry group and following the 2003 acquisition of Pharmacia by Pfizer, he moved to the Groton site. As a scientist, project leader and manager in the Groton Neuroscience chemistry group, Patrick led multiple programs into clinical trials. In 2011 he became a design head in neuroscience medicinal chemistry driving project delivery in support of the neuroscience portfolio. In 2016, Patrick became the head of the Neuroscience Medicinal Chemistry group and in 2017 the head of the Internal Medicine Medicinal chemistry group which includes the Applied Synthesis Technology group. In 2020, his responsibilities increased to include the discovery network group and the anti-viral medicinal chemistry efforts targeting protease inhibitors for COVID-19 leading to the discovery of Paxlovid. Patrick is the author and inventor on over 70 publications and patents.
