Curriculum Vitae

Google scholar profile

I’m currently a postdoctoral research associate at the Department of Mechanical and Aerospace Engineering at Princeton University, working with Dean 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.

Research Highlights

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.

Mechanism of Surface Reconstruction of an Oxide

“Sling-shot” hop mechanism in TiO diffusion facilitating the interconversion between the c(2x2) and c(4x4) TiO-rich reconstructions of BaTiO3(001) surface, predicted via the nudged elastic band method within a DFT framework.
