Dr. Benavides joined the faculty as Assistant Professor of Neurology in April 2017. He earned M.D. and Ph.D. degrees from the Medical Scientist Training Program at The University of Texas Southwestern Medical Center in Dallas, Texas. As a neuroscience graduate student in the laboratory of James A. Bibb, Ph.D., he employed a multidisciplinary approach using biochemistry, electrophysiology, transgenic rodent models, and animal behavior to study reward signaling, learning and memory, and mood-related behavior. Dr. Benavides completed adult neurology residency training at Johns Hopkins University School of Medicine in Baltimore, Maryland followed by fellowship training in the Division of Neuroimmunology and Neurological Infections. He also completed postdoctoral fellowship training in neuroscience at Johns Hopkins in the laboratory of Richard L. Huganir, Ph.D., where he used neuronal culture models to investigate the effects of autoantibodies on intracellular signal transduction cascades. Dr. Benavides directs a translational clinical neuroscience research program to investigate immune regulation of neuronal function, with particular interest in autoimmune encephalitis. The research program uses cell culture, primary neuronal culture, and rodent animal models combined with a multidisciplinary approach involving pharmacology, protein biochemistry, proteomics, cell biology, and molecular biology. The unifying goal of this research program is to identify novel therapeutic targets for neurologic diseases. Dr. Benavides holds board certification from the American Board of Psychiatry and Neurology and is involved in the Maryland Center for Multiple Sclerosis Treatment and Research.
