He was a neuro-anatomy instructor part-time as a medical student and he won the AMSA Special Appreciation Award from for teaching medical students in 1993.

After medical school, he spent one year training in Internal Medicine at Virginia Commonwealth University and spent six years training at Duke University Medical Center, where he completed a dual neurology-psychiatry residency training program and a neurophysiology fellowship. He accepted a faculty position in the Department of Neurology at MUSC in 2003. He worked at MUSC from 2003 through 2024, attaining the rank of Professor of Neurology. He joined the staff of the Ralph H. Johnson VA Medical Center in 2004 and continues to take care of patients and do research at this hospital.
At the Ralph H. Johnson VA Medical Center, he is the Director of an Epilepsy Centers of Excellence Consortium Site and does research to test new methods for recording EEG and automatically detecting patterns in EEG. He is an Adjunct Associate Professor in the Departments of Electrical and Computer Engineering and the School of Computing at Clemson University.
At the Charleston VAMC, he sees adults with epilepsy and sleep medicine disorders.
