Research Professors

Dr. James R. McBride

James received his B.S. from Florida Southern College in 1999 and his Ph.D. from Vanderbilt in 2004. James’ interests lay in using Z-Contrast Scanning Transmission Microscopy (Z-STEM), Energy Dispersive Spectroscopy (EDS) and Electron Energy-Loss Spectroscopy (EELS) to elucidate the atomic structure and composition of colloidal core and core/shell nanocrystals and their surfaces. Rutherford Back-Scattering has also been used to analyze the bulk composition of the core/shell samples and to identify impurities found in the semi-conducting polymer used in our photovoltaic devices. James manages and trains graduates students on the Tecnai Osiris TEM/STEM at Vanderbilt.

 

 

 

Dr. Oleg Kovtun

Dr. Oleg Kovtun, a native of Lviv, Ukraine, received his B. S. in Chemistry summa cum laude from Murray State University in 2007, followed by a Ph.D. in Chemistry from Vanderbilt University in 2013, where he pursued studies of the dopamine transporter membrane dynamics using antagonist-conjugated quantum dots under the direction of Dr. Sandy Rosenthal and Dr. Randy Blakely. Following his graduate work, Dr. Kovtun did a short stint as an analytical GC/GC-MS/HPLC chemist at McCoy & McCoy Laboratories, where he was responsible for providing efficient and accurate results on samples collected for regulatory compliance reporting and industry QC. Dr. Kovtun returned to the lab in 2015 to pursue postdoctoral training under the direction of Dr. Rosenthal. The central aim of his current research is to illuminate the molecular factors underlying neurotransmitter transporter and receptor dynamic dysregulation in mental illness through the use of quantum dot-based superresolution microscopy techniques.
