The Physicians

Anne H. Cross, MD graduated cum laude from the University of Alabama School of Medicine and was selected for the Alpha Omega Alpha medical honorary. After residency training in neurology at George Washington University in Washington , D.C., Dr. Cross spent six years as a fellow in multiple sclerosis and neuroimmunology at the National Institute of Health and Albert Einstein School of Medicine in New York. Dr. Cross received a fellowship from the National Multiple Sclerosis Society, and was named a Harry Weaver Neuroscience Scholar of the National Multiple Sclerosis Society. She joined the MS Center in 1991 as a specialist in MS and neuroimmunology. Currently, her research is funded by the National Institutes of Health and the Conrad N. Hilton Foundation.

Robert T. Naismith, MD received his medical degree from Case Western Reserve University in Cleveland, OH, where he was elected to AOA. He completed his Internal Medicine and Neurology training at Barnes-Jewish Hospital and was chosen Resident of the Year” in 2002. His research project as a Neurology resident on MS received the Levy Award from the Department of Neurology for best research by a resident. Dr. Naismith was selected as the first recipient of the Serono Fellow award from the National Multiple Sclerosis Society (NMSS). Dr. Naismith is Director of the John L. Trotter MS Clinic, Director of the Multiple Sclerosis Clinical Trials Program, and Neurology Clerkship Director for Medical Students doing their clinical rotations in neurology.

Laura Piccio, MD, PhD was trained in medicine and neurology in Milan Italy. She does research full-time and is funded by the National Institutes of Health, the U.S. Department of Defense, National MS Society and other non-profit organizations. Her main focus of research is on endogenous immune regulatory mechanisms involving the “TREM” family of molecules and adipokines and cytokines, and caloric restriction in the EAE model of MS. She is currently conducting a diet study in MS patients that is funded by the National MS Society.

Gregory Wu, MD, PhD was born and raised in Iowa. He attended college at Washington University in St. Louis before obtaining his MD and PhD degrees at the University of Iowa. Dr. Wu joined the Washington University MS Center after completing neurology residency and fellowship training in neuroimmunology at the University of Pennsylvania. His fellowship was supported by the National Multiple Sclerosis Society. He is actively pursuing research in multiple sclerosis, receiving a K08 career development award from the NIH for his work investigating the role of dendritic cells in an animal model for MS. His interests extend to other aspects of neuroimmunology, including the role of B lymphocytes in MS, and neuro-ophthalmology in relation to MS. His research is currently funded by the National Institutes of Health.

Salim Chahin MD MSCE is from Damascus Syria. He did his neurology residency at the University of Iowa, where he was neurology Chief Resident in 2101-2011. He trained in MS care and research at the University of Pennsylvania, and received the Masters of Science in Clinical Epidemiology degree from U of Penn in 2014. Dr. Chahin moved to Washington University in early 2017.

Courtney Dula – Research assistant for the DISCO-MS study, which is funded by The Patient-Centered Outcomes Research Institute (PCORI). The goal of this multi-center study is to determine if middle-aged and older persons with MS who have been stable for several years can safely stop their disease modifying treatments. Ms. Dula is the coordinator for several industry-sponsored research studies, as well.

Shannon Sides – Research assistant to Drs Naismith and Cross. Ms. Sides is the coordinator for our gradient echo MRI research studies. She plans the research visits and assists in the functional testing of research subjects. She can be contacted at 314 273-1599.
