Biographical Sketch 
Dr. Nicholas is originally from Pennsylvania and received his B.S. degree in 1982 from the University of Scranton. He then received his Ph.D. in Anatomy from the Graduate School of Biomedical Sciences in Galveston in 1987, and his M.D. degree from the University of Texas Medical Branch at Galveston in 1990. After medical school, Dr. Nicholas spent two years completing a post-doctoral fellowship in Neuroscience with Dr. Tomas Hökfelt at the Karolinska Institute in Stockholm, Sweden. In 1992, he returned to the United States and in 1996 concluded his neurology residency and became Assistant Professor of Neurology at UAB. He was promoted to Associate Professor in 2003 and presently holds joint appointments in the Departments of Neurobiology and Physiology/Biophysics. He also serves as Assistant Chief of Neurology at the Birmingham VA Medical Center, was Co-Director of the American Parkinson Disease Association Information and Referral Center at UAB and Director of the UAB Parkinson Disease Research Laboratory from 1997-2005. In 2006, Dr. Nicholas was given research appointments in the Civitan International Research Center and UAB's Center for Glial Biology in Medicine and Center for Neurodegeneration and Experimental Therapeutics.

Research/Clinical Interest
Parkinsonís Disease, Citrullinated Proteins, Adrenergic Receptors
Major basic science research interests of Dr. Nicholas include the pathophysiology of Parkinsonís disease, including protein degradation and the role of auto-immune antibodies and gliosis in neurodegeneration. Other interests include the neurochemical mechanisms responsible for levodopa-induced dyskinesia and the role of protein deimination (citrullination) in neurological diseases such as Parkinsonís disease, Alzheimerís disease and multiple sclerosis (and their animal models). Dr. Nicholas also has experience performing clinical research, including testing new treatments for Parkinson's disease, multiple sclerosis and cervical dystonia.
