Research in the Bugarin group focuses on catalytic reaction development with applications in natural product synthesis. Areas of fundamental interest include: the identification of new reactivity patterns, the evolution of related catalytic processes, and the development of new synthetic strategies. Specifically, we are pursuing new chemistry using azides, nucleophilic and electrophilic catalysis via N-heterocyclic carbenes, synergistic catalysis, redox economy, and metal-catalyzed tandem processes.

Dr. Bugarin received his BS in chemistry, pharmacy, and biology from Universidad Autónoma de Zacatecas in 2003, his MS from UTEP in 2005, and his Ph.D. from Texas A&M University in 2011. His doctoral training under the direction of Dr. Brian T. Connell focused on asymmetric catalysis, including ligand, catalyst, and reaction design. He then spent one year as a postdoctoral associate with Professor Javier Read de Alaniz at UC Santa Barbara working on the mild aerobic oxidation of hydroxylamines and hydrazines. Dr. Bugarin joined the faculty at UT Arlington in Fall 2012. His research interests are in the development of new organic and organometallic reactions, or more specifically, the efficient construction of carbon–nitrogen bonds, redox economy, synergistic catalysis, and their application in total synthesis, materials, and bioactive molecules.
