BIOGRAPHY
David is a patent agent practicing in the areas of chemical, materials, and related engineering technologies. David earned a B.A. in Chemistry and a B.S.E. in Chemical and Biomolecular Engineering from the University of Pennsylvania, followed by a Ph.D. in Theoretical and Computational Chemistry from Harvard University. His research focused on atomistic simulations of metal oxides, alloy surfaces, and heterogeneous catalysis, working closely with experimental collaborators and data scientists.
Following his Ph.D., David conducted postdoctoral research in catalysis at the University of California, Los Angeles (UCLA). Before becoming a registered patent agent, he was a Senior Engineer on Samsung Semiconductor’s Process Simulation team, where he developed and applied computational chemistry models for semiconductor manufacturing processes.
In his spare time, David enjoys journaling and playing classical piano.
