Parkinson and Other Movement Disorders Center's Fellows and Students

Our center offers one year sub-specialty training in Movement Disorders and an optional second year for research training to clinicians with residency training in Neurology. We also offer research fellowships in movement disorders to scientists from different backgrounds.

2019-2020 Clinical Fellows

John Legge, MD

Dr. Legge finished his undergraduate studies with a dual major in Chemistry and Mathematics at Christian Brothers University in Memphis, Tennessee. He graduated from the University of
Tennessee Health Science Center College of Medicine and completed Neurology residency at Virginia Commonwealth University in Richmond, Virginia. His interests include medical economics and policy, science fiction and teaching.

Steven Fan Zhang, DO

Dr. Zhang finished his undergraduate studies with a dual major in Neuroscience and Genetics at Cornell University. He completed his medical degree at Nova Southeastern University, where he was chosen for a research fellowship that offered him three years of tuition coverage. He completed his Neurology residency at Emory University. His interests include Deep Brain Stimulation, traveling, fine dining, weight lifting, photography, hiking and various sports.

Current Research Fellows

Ece Bayram, MD, PhD 

Dr. Bayram obtained her medical degree and consequently her PhD in Neurosciences from Ankara University, Turkey. After her first-year of research fellowship at Lou Ruvo Center for Brain Health, Las Vegas, with a focus on Parkinson’s disease and Alzheimer’s disease, she joined our team as a research fellow in 2019. Her research interests include neuroimaging and cognition in neurodegenerative diseases. She is also interested in teaching and expanding educational resources to non-English speaking patients and clinicians.

Katherine Longardner, MD

Dr. Longardner completed her undergraduate studies with dual major in Biology and Spanish at Florida State University (FSU) in Tallahassee, Florida. She graduated from FSU College of Medicine in 2014 and went on to complete her internship year and Neurology residency at UC San Diego. She concluded a one-year clinical fellowship at our center and is currently doing a second-year of research fellowship under the mentorship of Dr. Litvan. Her research interests include orthostatic hypotension and cognition in people with neurodegenerative disorders such as Parkinson’s disease. Dr. Longardner is fluent in English and Spanish.

Saba Rezvanian, PhD

Dr. Rezvanian earned two Bachelor of Science degrees in biomedical and electrical engineering and Master of Science and PhD in biomedical engineering from Arizona State University. During her doctoral studies, she studied human risk assessment and prevention. She introduced new biomarkers to detect freezing of gait and diagnose motor subtypes of Parkinson's disease. She also assessed the effects of treadmill-delivered perturbation training on gait dynamic stability while walking and adaptability of locomotor system in resisting to perturbations. Since 2019, Dr. Rezvanian has been doing her research fellowship at our center with focus on fall risk assessment and prevention among movement disorder patients.
