Alex Kosanovich

Alex received his B.A. in chemistry from Carleton College in Northfield, MN in June of 2014. While there, he conducted research under Assistant Professor Matthew T. Whited, developing and studying the synthesis, characterization, and insertion reactivity of bis-phosphine-supported rhodium silylamides, and their ability to deoxygenate CO, CO2, and various other heteroallenes at room temperature. Alex arrived in College Station in July 2014, and joined the Ozerov group later that year as an NSF LSAMP BTD graduate fellow. His current research revolves around the synthesis of novel rhenium complexes in a pincer ligand context, and their applications in catalytic transformations of interest.

Chris Pell

Chris spent the summer of 2011 with the Ozerov group as a participant in the NSF REU program where he studied the kinetics of C-N reductive elimination from (POCOP)Rh complexes. After Chris received his B.S. in Chemistry from the State University of New York at Plattsburgh in 2012, he rejoined the Ozerov group in August 2012 as a graduate student at Texas A&M University. Since then he has studied (POCOP)Rh complexes as catalysts for C-S coupling and alkyne dimerization. He has also investigated palladium and iridium pincer complexes as catalysts for the dehydrogenative borylation of terminal alkynes. Outside of the lab, Chris enjoys travelling around Texas, finding new restaurants, and exploring new and diverse music.  Chris defended his Ph D. and has taken a job with Intel in Oregon.
