Biographies of Graduate Students

Brandon Zoellner (5th year)
Brandon is a native of Pinehurst, North Carolina. In 2011, he graduated with a Bachelor's of Science degree in chemistry at the College of Charleston in Charleston, South Carolina. After receiving his undergraduate degree, he worked in the research laboratory of Dr. Lavrich for a year on the synthesis of peptides. Brandon joined the chemistry graduate program at North Carolina State Univesity in the Fall of 2012 to begin his doctoral studies under the mentorship of Prof. Paul A. Maggard . His research project focuses on the synthesis of solid solutions of mixed-metal oxides in the tantalate and niobate systems, their structural characterization from powder X-ray diffraction refinements, electronic structure calculations, as well as characterization of their optical and photoelectrochemical properties.
