Curriculum Vitae


Biographical Sketch

Dr. Nathan I. Hammer was born in Johnson City, TN and was valedictorian of Franklin High School in 1994. He received an Honors B.S. in Chemistry Degree from the University of Tennessee in 1998 and received his Ph.D. in Physical Chemistry & Chemical Physics under the direction of Prof. Bob Compton at the University of Tennessee in 2003. His doctoral research focused on resonant electron transfer processes, the creation and manipulation of very weakly bound (0.5-50 meV) negative ions, and the interaction of light with chiral systems. This research resulted in a number of publications, including two in Physical Review Letters. After graduation Dr. Hammer joined Prof. Mark Johnson as a postdoctoral researcher (2003-2005) at Yale University, where he studied the spectroscopy of fundamental aqueous systems. This work resulted in fifteen publications, three of which were in Science magazine, and was listed among Science’s Top 10 Breakthroughs of 2004. Dr. Hammer then served as an Intelligence Community Postdoctoral Fellow in the Department of Chemistry at the University of Massachusetts (2005-2007) working with Prof. Michael Barnes. At UMass, Dr. Hammer studied a number of fundamental systems using single molecule spectroscopic techniques. Important accomplishments include discovering blinking suppression in quantum dot nanostructures, probing the chiroptical response of single molecules, and unraveling the origins of spectroscopic defects in fluorene-based organic light emitting diode (OLED) devices. Dr. Hammer joined the University of Mississippi (Ole Miss) Department of Chemistry and Biochemistry in 2007. He was honored as an Ole Miss Faculty Research Fellow in 2008 and in 2010 received a Faculty Early Career Development (CAREER) Award from the National Science Foundation (NSF) to spectroscopically track the evolution of noncovalent interactions from the single molecule level to the condensed phase. Dr. Hammer was promoted to professor in 2019 and was named the Margaret McLean Coulter Professor of Chemistry & Biochemistry in 2020. He currently has six graduate students, a post doc, and over 10 undergraduate students working under his direction in his chemical physics laboratories at Ole Miss. Dr. Hammer teaches general chemistry, as well as physical chemistry graduate and undergraduate courses and the undergraduate physical chemistry laboratories. He has also served as chair of the Ole Miss Local Section of the American Chemical Society in 2010, 2011, 2015, and 2018.
