Patrick J. Walsh

Patrick J. Walsh is the Rhodes-Thompson Professor of Chemistry at the University of Pennsylvania’s College of Arts & Sciences. He leads the Walsh Group, focusing on catalytic methodologies and synthetic chemistry with an emphasis on merging organic/inorganic synthesis and exploring unusual reactivity. His educational background includes a B.A. in Chemistry from UC San Diego (1986), a Ph.D. in Chemistry from UC Berkeley (1991), and a NSF Postdoctoral Fellowship at The Scripps Research Institute (1991–1994).

His research interests span catalysis, radical chemistry, and transition metal systems, with key projects involving cation-pi interactions for C-H activation, super electron-donor (SED) 2-azaallyl anions, and photoredox-driven reactions. The group also develops pharmaceutical analogs like bioisosteric BCP compounds and explores transition metal-free syntheses for complex molecules.

Recent publications highlight advancements in Ce(III) photoredox systems, Smiles rearrangement applications, and nickel-catalyzed enantioselective reactions. The work demonstrates a focus on sustainable catalytic strategies, mechanistic innovation, and novel compound construction.
