Julia Kaltschmidt
Professor of Neurosurgery
Current Research and Scholarly InterestsThe lab’s primary research interest is to understand how specific neuronal circuits are established. We use mouse genetics, combinatorial immunochemical labeling and high-resolution laser scanning microscopy to identify, manipulate, and quantitatively analyze synaptic contacts within the complex neuronal milieu of the spinal cord and the enteric nervous system.

Spyros Karadimas, MD, PhD
Assistant Professor of Neurosurgery
BioDr. Spyridon Karadimas is a board-certified, fellowship-trained cerebrovascular neurosurgeon and physician-scientist with Stanford Health Care. He is also an assistant professor in the Department of Neurosurgery at Stanford University School of Medicine.
Dr. Karadimas offers advanced, personalized treatment for complex vascular disorders of the brain, neck, and spine in both adults and children. His expertise spans brain aneurysms, arteriovenous malformations, cavernous malformations, arteriovenous fistulas, Moyamoya disease, stroke, and carotid artery disease. Dr. Karadimas is a rare combination of surgeon, scientist, and innovator dedicated to advancing patient care and shaping the future of cerebrovascular neurosurgery.
Dr. Karadimas directs a basic and translational research program focused on the neural circuits of motor control and stroke recovery. His laboratory integrates systems neuroscience, in vivo imaging, electrophysiology, and brain-computer interface development to uncover the principles of neuroplasticity, or how the brain adapts to change. This knowledge allows him to create new ways to help people move again after a brain injury.
Dr. Karadimas has published his research as first author in peer-reviewed journals such as Nature, Nature Neuroscience and Science Translational Medicine. His work has received editorial highlight at Nature Reviews Neuroscience. He has presented to his peers at international, national, and regional meetings, including those of the American Academy of Neurological Surgery, American Association of Neurological Surgeons (AANS), European Association of Neurosurgical Societies, and World Federation of Skull Base Societies.
Dr. Karadimas is a fellow of the Royal College of Surgeons of Canada and American Association of Neurological Surgeons as well as member of the Congress of Neurological Surgeons, and the North American Skull Base Society. -

Prashanth Krishnamohan, MD
Clinical Associate Professor, Adult Neurology
Clinical Associate Professor (By courtesy), NeurosurgeryBioDr. Krishnamohan is a board-certified, fellowship-trained neurologist. He is a clinical assistant professor of neurology and neurological sciences and, by courtesy, of neurosurgery at Stanford University School of Medicine. In addition, he is Medical Director of the Neurosciences Service Line at Stanford Health Care – ValleyCare and is Medical Director of its Stroke program.
Dr. Krishnamohan excels in the diagnosis and treatment of neurological conditions. His clinical interests include the management of stroke, epilepsy, concussion, and coma. With every patient, his goal is to provide personalized care designed to optimize neurological function for the best possible clinical outcome and quality of life.
He has published extensively on topics including innovations in stroke care quality management and measurement, rapid bedside evaluation of seizures in the ICU, and EEG metrics in comatose cardiac arrest patients. Articles by Dr. Krishnamohan have appeared in Neuroanesthesia and Neurocritical Care, Quality Management in Healthcare, Current Infectious Disease Reports, and other journals. He has presented his research findings at the annual meetings of the Neurocritical Care Society and American Academy of Neurology.
He has authored chapters on post-concussive syndrome, stroke, and other conditions for the guidebook Ferri’s Clinical Advisor. In addition, he is a reviewer for the Journal of Neuroscience Nursing, Neurohospitalist, and the Journal of Neurology, Neurosurgery, and Psychiatry.
Dr. Krishnamohan has won recognition from Stanford Health Care, the Institute for Healthcare Improvement Open School, the University of Kentucky College of Medicine, and PSG Institute of Medical Sciences and Research – the latter two his alma maters.
Dr. Krishnamohan is a member of the Neurocritical Care Society, American Academy of Neurology, and American Heart Association/American Stroke Association. He volunteers as a community health educator with numerous organizations. -
Kathryn Kvam
Clinical Associate Professor, Adult Neurology
Clinical Associate Professor (By courtesy), NeurosurgeryCurrent Research and Scholarly InterestsDr. Kvam's research focuses on 1) how to measure quality of care for patients with neurologic disease, 2) the value and impact of neurohospitalist models of care on patient outcomes and trainee education and 3) outcomes in rare diseases like autoimmune encephalitis.

Mable Lam
Instructor, Neurosurgery
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. -
Maarten Lansberg, MD, PhD
Professor of Neurology and Neurological Sciences (Adult Neurology) and, by courtesy, of Neurosurgery
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.
