Lan Luo (4th year)
Lan Luo is a native of Taiyuan, China. She graduated from the Nanjing University of Science & Technology in the Department of Chemistry. In the fall 2008, she performed research under the supervision of Professor Junwu Zhu in the Key Laboratory of Soft Chemistry and Functional Materials on the synthesis of graphene-MnS nanocomposites. After completing her Bachelor’s degree in 2010, she began her doctoral studies at North Carolina State University under the mentorship of Prof. Paul A. Maggard. Her doctoral research focuses on heterometallic oxide/organic hybrid solids, characterization of their structures by single-crystal X-ray diffraction, and new investigations of their optical and photocatalytic properties.

Jonathan Boltersdorf (3rd year)
Jonathan Boltersdorf is originally from Woodbridge, Virginia. He graduated from James Madison University in Harrisonburg, VA with a Bachelor's of Science in Chemistry in 2011. As an undergraduate, he worked under the supervision of Prof. Barbara Reisner on the synthesis and characterization of porous inorganic-organic frameworks derived from poly(triazolyl)borate ligands. He began his doctoral studies in the research group of Prof. Paul A. Maggard in June of 2011. His current research efforts involve the solid-state and flux synthesis of silver, lead, and bismuth-containing mixed-metal oxides. New compositions and structures of crystalline oxides are being investigated in order to understand the relationship between their structural features and their optical, electronic, and photocatalytic properties.

Ian Sullivan (3rd year)
Ian is originally from Point Pleasant, New Jersey and received his Bachelor's of Science degree from Rutgers University. He next worked at a start-up company named Liquid Light, where he performed research on the pyridinium-catalyzed electrochemical reduction of carbon dioxide. He began his doctoral studies in the Fall of 2011 under the direction of Prof. Paul A. Maggard, and is currently investigating the structures and photoelectrochemical properties of Cu(I) tantalate phases. His research interests are in the areas of new semiconducting materials, artificial photosynthesis, nanoparticle synthesis, and dye-sensitized solar cells.

Brandon Zoellner (2nd 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.
