JOHN MARK P. MARTIREZ, Ph. D.
I’m currently an Assistant Project Scientist in the Department of Chemical and Biomolecular Engineering at University of California, Los Angeles, working with UCLA’s Executive Vice Chancelor and Provost Emily A. Carter.
I use state-of-the-art computational tools in fields where atomic-scale information delivers unparalleled chemical design principles. The main thrust of my work is using first-principles density functional theory (DFT) and embedded correlated wavefunction (emb-CW) methods to guide experimentalists in finding alternative and unconventional reaction pathways and catalysts for industrially relevant reactions. This includes computational investigations on manipulation of reactions via new or surface-modified heterogeneous catalysts and introduction of co-catalysts. The foundation of my work lay on the identification of key species and pathways in catalysis from first-principles quantum mechanics.

Plasmon-Driven Catalysis on Metals
N2 dissociation pathway on a Fe-doped Au(111) surface. We show that the N2 dissociation barrier can be effectively reduced via accessing electronically excited-states, which we predicted via the embedded n-electron valence second order perturbation theory.
