Christopher Kelly

Web Master, Scientist @ Janssen R & D

A native New Yorker, Chris’s interest in synthesis was sparked during his undergraduate studies at Stonehill College. At Stonehill, Chris worked under Prof. Leon Tilley and completed a targeted synthesis of 1-(trifluoromethyl)bicyclo[1.1.0]butane. Chris moved to UCONN in 2010 to perform his doctoral work under Prof. Nicholas Leadbeater. At UCONN, he worked in the areas of organofluorine chemistry and sustainable oxidative processes. In 2015, he continued his training under Prof. Gary Molander at the University of Pennsylvania as an NIH Postdoctoral Fellow. At Penn, Chris’s research utilized photoredox catalysis to enable C–C bond construction. After a short stint (2018-2019) in academia as an Assistant Professor at Virginia Commonwealth University, he joined Janssen's Discovery Process Research team to tackle problems relating to human health. However, because of his passion for teaching, Chris also serves as the lecturer for CHEM 746, a graduate-level organic chemistry course at Penn, since Fall 2020.
