    Edward F. and Irene Thiele Pimley Professor of Neurology and the Neurological Sciences and Professor, by courtesy, of Neurosurgery

    Current Research and Scholarly InterestsMy research addresses one of the most devastating and poorly treated symptoms that can develop in people with Parkinson's disease - Dementia. We use biological markers, multi-modal neuroimaging and genetics to understand the different underlying causes of dementia and to understand why dementia develops more quickly in some patients, but not others.

    Having grown up in Austria, Dr. Pulli moved to the US after completing medical school in Innsbruck, Austria. He completed post-doctoral research training in stroke imaging in the Division of Neuroradiology at the Massachusetts General Hospital, as well as in experimental molecular imaging techniques of neuroinflammatory disorders at the Center for Systems Biology of Massachusetts General Hospital and Harvard Medical School.

    He completed residency training in Radiology and fellowship training in Diagnostic Neuroradiology at the Massachusetts General Hospital in Boston. He then completed a second fellowship in interventional neuroradiology/neurointerventional surgery at Stanford University School of Medicine.

    After having graduated from fellowship, Dr. Pulli then spent more than a year practicing Interventional Neuroradiology at Pacific Neuroscience Institute in Los Angeles. He employs state-of-the-art minimally invasive endovascular and percutaneous surgical techniques to treat patients with brain aneurysms, arteriovenous malformations, dural arteriovenous fistulas, carotid artery stenosis, acute stroke, chronic subdural hematoma, idiopathic intracranial hypertension, vascular tumors, and chronic back pain.

    His research focuses on advanced imaging techniques for acute ischemic stroke and other neurovascular diseases. He has authored more than 40 peer-reviewed publications and received scientific grants from institutions such as the Radiological Society of North America and the Ernst Schering Foundation. In addition, he has made invited presentations to his peers at meetings of organizations such as the American Society of Neuroradiology, Radiological Society of North American, European Congress of Radiology, and Western Neuroradiological Society.

    He is a member of the Society of Neurointerventional Surgery.

  • Ashwin Ramayya, MD, PhD

    Ashwin Ramayya, MD, PhD

    Assistant Professor of Neurosurgery

    BioDr. Ramayya is an assistant professor in the Department of Neurosurgery. He specializes in the treatment of patients with chronic pain, movement disorders, epilepsy, and traumatic brain injury. His research program will focus on understanding brain mechanisms underlying pain experience and how to alleviate pain using brain stimulation.

    Dr. Ramayya specializes in neuromodulation, including deep brain stimulation (DBS), spinal cord stimulation, MRI-guided laser therapy, and focused ultrasound. Dr. Ramayya obtained his MD and PhD from the University of Pennsylvania, where he also completed his neurosurgery residency and a fellowship in stereotactic and functional neurosurgery.

    His research efforts have identified neural substrates underlying learning, memory, and decision-making using computational behavioral modeling, neurophysiology, and neuroimaging.

    Dr. Ramayya has published in numerous peer-reviewed journals, including the Journal of Neuroscience, NeuroImage, and Cerebral Cortex. He has also presented his work at national and international meetings, including those for the American Association of Neurological Surgeons and the Pan Philadelphia Neurosurgery Conference.
