Julia Kaltschmidt
Associate 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.

Vanessa W.Y. Kan
Postdoctoral Scholar, Neurosurgery
BioI am a second-year postdoctoral researcher in Irene Llorente’s laboratory at the Department of Neurosurgery. I completed my Ph.D. at the Graduate School of Systemic Neurosciences GSN-LMU in Munich, Germany, where I was trained as a circuit neuroscientist. During my doctoral work, I focused on dissecting the circuit mechanisms underlying cortical hyperexcitability in ALS, uncovering the pathophysiological role of hyper-responsive layer 2⁄3 neurons (one of the main inputs to layer 5) in the disease course. Currently, my research bridges circuit neuroscience, stem cell biology, and bioinformatics to explore mechanisms of neural repair and regeneration. I utilize advanced experimental and computational tools, including in vivo calcium imaging in awake, freely behaving rodents; machine learning-based motion sequencing (MoSeq); anterograde and retrograde viral tracing techniques; and transplantation of iPSC-derived glial-enriched progenitors and cortical interneurons. In parallel, I apply spatial transcriptomics and single-cell RNA sequencing to map cell-type–specific interactions and molecular signatures during neural circuit remodeling.
My research focuses on understanding the circuit mechanisms underlying neurological conditions such as stroke and identifying how cell-based therapies mediate repair. The ultimate goal of my work is to uncover molecular and cellular processes that promote graft–host integration and functional recovery, paving the way for next-generation regenerative therapies for the injured brain.
In addition to translational research, I am also passionate about scientific education and outreach. I mentor community college students twice a year through the Stanford Science Small Group, in which I share my own experience in research and guide them through the research process. To expand my outreach efforts, in the past summer, I collaborated with Invent Your Own Future as well as The Hong Kong Polytechnic University and organized a summer camp on Neuroscience x AI research for over 20 high school students in Hong Kong. -
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 in peer-reviewed journals such as Nature Neuroscience, Nature, Science Translational Medicine, and Journal of the Neurological Sciences. 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 Congress of the 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.
