The graduate students Arian Ghorbanpour and Hieu Doan are the first students to join Lars Grabow's computational catalysis group at the University of Houston. Arian is co-advised with Jeff Rimer and is working on the synthesis and simulation of ZSM-5 core-shell particles. Hieu uses density functional theory and microkinetic modeling to investigate bifunctional catalysts for CO oxidation and methane activation.
