Dr. Wang carried out doctoral and postdoctoral research on the synthesis and reactivity of organometallic and coordination compounds.  He began his independent career at CU Denver in 1997, and studied the synthesis, structures, and properties of metal-organic frameworks (MOFs).  He has been studying computational organometallic chemistry in recent years, with interests in elucidating the mechanisms of important catalytic reactions (olefin metathesis, C-H functionalization, etc.) and designing synthetically viable novel molecules.  Dr. Wang has been a visiting scholar at MIT and the Chinese Academy of Sciences.

We use computational methods to (1) design novel organometallic and coordination compounds and (2) study the mechanisms of important reactions, particularly transition metal-catalyzed organic transformations. Our research addresses the experimental–theoretical synergy and provides ideas and insights that will aid in the work of experimentalists.
