Ari J. Green, MD, MCR



Dr. Ari J. Green is medical director of the UCSF Multiple Sclerosis (MS) Center and director of the UCSF Neurodiagnostics Center. He treats adults and children with MS and other inflammatory diseases of the central nervous system and has expertise in treating visual problems resulting from these conditions.

In his research, he addresses how MS affects the visual system and methods to track and predict the course of the disease. He also uses advanced retinal imaging and electrophysiology to investigate the retina and optic nerve and the relationships between inflammation, demyelination and neurodegeneration in the disease and to better understand injury to nerve fibers of the brain in MS.

Dr. Green earned a medical degree at Duke University School of Medicine in Durham, N.C., and completed an internal medicine internship in 2002 and neurology residency in 2005, both at UCSF.  He completed neuro-immunology and neuro-ophthalmology fellowships at UCSF and has won several awards including a Howard Hughes Medical Institute Early Career Scientist Award and a clinician-scientist award from the National Multiple Sclerosis Society and American Academy of Neurology Foundation.



Jeffrey M. Gelfand, MD, MAS


Dr. Gelfand received his undergraduate degree in history from Princeton University, graduating summa cum laude, and earned his medical degree from Harvard Medical School. He completed neurology residency at UCSF, where he served as a chief resident. He went on to do subspecialty fellowship training in multiple sclerosis and neuroimmunology at the UCSF MS Center. He is board-certified in neurology.

Dr. Gelfand is a recipient of a 2011 American Academy of Neurology clinical research training fellowship. He is currently a UCSF CTSI KL2 Scholar. He is a two-time winner of the Newman Award (2009 and 2011) from the San Francisco Neurological Society for clinical research.

Dr. Gelfand directs the UCSF MS Center Clinical Fellowship Training Program. He received the 2014 Robert B. Layzer Award for Resident Teaching, given annually by the neurology residents at UCSF. He received the 2015 Excellence in Teaching Award from the Academy of Medical Educators at UCSF, which is awarded by his peers.






Christian Cordano, MD, Postdoctoral Scholar





Dr. Cordano completed his MD followed by a residency in Neurology at the University of Genoa, in Italy. This was followed by a fellowship in Neuroimmunology at the University of Genoa. During his residency and fellowship in Genoa he worked with Professor Antonio Uccelli for six years, carrying out clinical trials in MS that included the use of OCT and VEP to monitor disease.

Dr. Cordano subsequently decided to focus his career on MS research, coupling his dual passions for neuro-ophthalmology and neuro-immunology.  He joined Dr. Ari Green´s Lab at UCSF as a Postdoctoral Research Fellow in August 2014, funded by a fellowship from FISM (Italian Multiple Sclerosis Foundation). His work is focused on visual electrophysiologic alteration in Experimental Autoimmune Encephalomyelitis models, trying to characterize the course of electrophysiologic alterations and neuronal injury following demyelination. He is currently a PhD candidate in the Department of Experimental Medicine at the University of Genoa, and will also complete a degree in Economics.  Dr. Cordano grew up in Genoa.  In his free time, he loves to travel, cheer on his soccer team (Genoa), and read comics and classics.





Christy K. Sheehy, PhD, Postdoctoral Scholar


Christy K. Sheehy received both her BS and MS degrees in Optics from the University of Rochester in Rochester, NY and most recently her PhD in Vision Science from the University of California, Berkeley in December of 2015. Her interests lie in the fields of high-resolution retinal imaging, optical engineering, and retinal eye-tracking. As a postdoctoral scholar in the Green lab, she plans to study how fixational eye movements in patients with neurodegenerative disease differs from those in normal healthy control subjects. She is passionate about finding ways to use non-invasive retinal imaging technologies as early-stage screening tools for patients of neurodegenerative disease.  Additionally, Christy is the Co-founder of a start-up, C. Light Technologies, whose mission is to commercialize the eye-tracking technology she designed and built for her PhD (the TSLO) to use as a future neuro-diagnostic. When she’s not doing research or start-up activities, Christy loves to salsa dance, paddleboard, go camping, and explore new cooking recipes.






Johnny H. Sin, BA, Clinical Research Coordinator


Johnny Sin completed his BA in Molecular and Cell Biology: Immunology from the University of California, Berkeley in Berkeley, CA. His scientific interests include unraveling the mysteries of autoimmune disorders, especially Multiple Sclerosis. Johnny plans to attend medical school Fall 2020. Outside of Sandler, Johnny spends his weekends volunteering with the Special Needs Aquatic Program (SNAP), playing soccer and doing graphic design.



Tracy T. Tran, BA, Clinical Research Coordinator



Tracy T. Tran completed her BA in Molecular and Cell Biology: Biochemistry & Molecular Biology at University of California, Berkeley in Berkeley, CA. She is interested in the biomechanics of neurodegenerative disease. Tracy plans to attend medical school Fall 2021. In her free time, Tracy does pilates and surfs.
