Robert Bachman
Chemistry Chair, F.B. Williams Professor of Chemistry,
Director of the First-Year Program
Spencer Hall 263 / ext. 1336

Rob Bachman earned his B.A. and Ph.D. in Chemistry at Rice University with a focus in inorganic, organometallic and organic chemistry. Prior to beginning his faculty career, Professor Bachman worked at the Technical University of Munich as an Alexander von Humboldt Fellow investigating the unique chemistry of gold. Professor Bachman's current research focuses on the construction of new metal-containing liquid crystalline materials with interesting, and potentially useful physical properties. He has also been active in a collaborative effort to study the water chemistry of local reservoirs. Professor Bachman teaches a variety of upper level courses in inorganic chemistry, including Inorganic Chemistry, Bioinorganic Chemistry, Structural Methods, Materials Chemistry and Advanced Environmental Geochemistry. At the introductory level, he teaches Advanced General Chemistry and participates in the department's General Chemistry program. He has also recently developed interests in the analysis of cultural artifacts and art objects as a teaching opportunity.

Evan E. Joslin
Associate Professor of Chemistry
Spencer Hall 256 / ext. 3549

Evan E. Joslin earned an B.A with ACS certification in Chemistry from Agnes Scott College in 2008 and a Ph.D. in Inorganic Chemistry (specifically Organometallic Chemistry) from the University of Virginia in 2013. After earning her Ph.D. she taught at Haverford College in Pennsylvania for a year. She then completed her postdoctoral work at The Johns Hopkins University in bioinorganic chemistry studying metallophorphyrin chemistry. Since 2016, she has been a faculty member in the Department of Chemistry at Sewanee, where she is currently a tenured Associate Professor. Her current research focuses on the synthesis of cobalt complexes for transfer hydrogenation and amine dehydrogenation reaction. She teaches the following courses at the University: Organic Chemistry, Solution and Solid-State Chemistry, Inorganic Chemistry, Advance Topics in Inorganic Chemistry.

Rongson Pongdee
Professor of Chemistry
Spencer Hall 258 / ext. 1846

Ron Pongdee received a B.S. in Chemistry from Vanderbilt University and his Ph.D. in Organic Chemistry from Texas A&M University working with Dr. Gary A. Sulikowski. He then elected to pursue postdoctoral studies in mechanistic enzymology at The University of Texas at Austin under the guidance of Professor Hung-wen Liu. His research interests lie within two main areas: (1) the design and development of natural products as new antibacterial and/or anticancer agents for drug discovery purposes and (2) the mechanistic elucidation of novel enzyme catalyzed reactions involved in the biosynthesis of various secondary metabolites containing interesting biological profiles. Students in his research group receive an interdisciplinary training spanning the areas of Biochemistry, Medicinal Chemistry, Molecular Biology, and Organic Chemistry. At Sewanee, Ron teaches both the lecture and laboratory components of the Organic Chemistry sequence (CH 201/202).
