    Current Research and Scholarly InterestsMyelin is required for rapid nerve signaling by insulating axons to accelerate action potential propagation. Myelin-forming cells of the central nervous system, called oligodendrocytes, orchestrate one of the most complex morphological transformations in neurobiology. Each oligodendrocyte can extend multiple processes that selectively wrap axons in tens to hundreds of spiraling membrane layers, forming myelin sheaths that vary in thickness and length. Furthermore, oligodendrocytes can respond to neural activity by adding new sheaths or by changing the geometry of pre-existing sheaths to tune neural circuitry, a process known as adaptive myelination.

    What are the membrane trafficking mechanisms that drive adaptive myelination in oligodendrocytes?

    How can these mechanisms be stimulated to promote myelin regeneration in disease?

    By using transgenic mouse models and primary oligodendrocytes, we have found that SNARE-mediated exocytosis drives membrane addition in myelin sheaths. Current research is focused on how these pathways in oligodendrocytes may be regulated during adaptive myelination.

    Current Research and Scholarly InterestsMy research involves the design and conduct of clinical trials to discover new treatments for patients who have suffered a stroke. These trials span treatment of acute stroke, stroke recovery, and stroke prevention. My research in acute stroke is primarily focused on the use of advanced neuroimaging methods (CT and MRI) to select patients who are most likely to benefit from therapies aimed at restoring blood flow to the brain in patients who have suffered a stroke.

  • Simon Levinson

    Simon Levinson

    Affiliate, Dean's Office Operations - Dean Other
    Resident in Neurosurgery

    BioSimon was born and raised in and around New York City. He moved to California to attend the University of California, Los Angeles (UCLA) where he obtained undergraduate degrees in both political theory and neuroscience. Simon continued his education at UCLA where he attended the David Geffen School of Medicine. While a medical student he worked under the mentorship of Dr. Carlos Cepeda to investigate the cellular mechanisms underlying pediatric epilepsy. Additionally, under the mentorship of Dr. Ausaf Bari he created an MRI based structural atlas of the human brainstem. Simon is currently undergoing clinical training in neurologic surgery at Stanford University. He is interested in understanding how neural networks function and contribute to disease and how they can aid in developing novel treatment therapies. Outside of medicine, Simon enjoys spending time with his wife, going for hikes with their dog, traveling, listening to audiobooks, and running.

    Michael Lim, M.D.

    Professor of Neurosurgery and, by courtesy, of Radiation Oncology (Radiation Therapy), of Medicine (Oncology), of Otolaryngology - Head & Neck Surgery (OHNS) and of Neurology

    BioDr. Lim is the Chair of the Department of Neurosurgery and a board-certified neurosurgeon specializing in brain tumors and trigeminal neuralgia.

    Dr. Lim’s clinical interests include the treatment of benign and malignant brain tumors, with special interest in gliomas, meningiomas, metastatic tumors, and skull base tumors. Dr. Lim also specializes in surgical treatments for trigeminal neuralgia. During his time at Johns Hopkins, Dr. Lim built one of the largest brain tumor and trigeminal neuralgia practices and utilized the most advanced surgical technologies and techniques for his patients. As a passionate voice for patient experience, he has been recognized by his peers and patients for his integrity and compassionate care, including a Service Excellence Award from HealthNetwork Foundation.

    As a mentor, he has garnered numerous teaching awards, including being honored as an outstanding teacher by Johns Hopkins University School of Medicine. He is actively involved in shaping education for neurosurgery and oncology across the United States and around the world. He is the recipient of the prestigious 2023 Abhijit Guha Award in Neuro-Oncology.

    Dr. Lim’s research interests focus on harnessing the immune system to fight cancer. His laboratory focuses on understanding mechanisms of immune evasion by cancer cells. He has successfully translated his findings from the laboratory to the clinics and has conducted and led several large national immunotherapy clinical trials for brain tumors.

    Dr. Lim’s bibliography contains well over 300 articles on topics such as immunotherapy for glioblastoma, long-term survival of glioma patients treated with stereotactic radiation, and treatment of neuropathic pain. His work has appeared in Science Translational Medicine, Clinical Cancer Research, Lancet Oncology, Nature Immunology, and many more publications. He also has written 20 book chapters and monographs.

    Dr. Lim is a world leader in immunotherapy for brain tumors. In addition to being invited world-wide to give lectures and seminars, he has given platform presentations on the topics of immunotherapy for brain tumors, neurosurgical techniques and management of brain tumors at the American Society of Clinical Oncologists, American Academy of Neurological Surgeons, Radiological Society of North America, Annual Symposium on Brain and Spine Metastases, Congress of Neurological Surgeons, and other meetings.
