Melanie Hayden Gephart
Professor of Neurosurgery and, by courtesy, of Neurology and Neurological Sciences
BioI am a brain tumor neurosurgeon, treating patients with malignant and benign tumors, including gliomas, brain metastases, meningiomas, and schwannomas. I direct the Stanford Brain Tumor Center and the Stanford Brain Metastasis Consortium, collaborative unions of physicians and scientists looking to improve our understanding and treatment of brain tumors. My laboratory seeks greater understanding of the mechanisms driving tumorigenesis and disease progression in malignant brain tumors. We study how rare cancer cell populations survive and migrate in the brain, inadvertently supported by native brain cells. We develop novel cerebrospinal fluid-based biomarkers to track brain cancer treatment response, relapse, and neurotoxicity. Our bedside-to-bench-to-bedside research model builds on a foundation of generously donated patient samples, where we test mechanisms of brain cancer growth, develop novel pre-clinical models that reliably recapitulate the human disease, and facilitate clinical trials of new treatments for patients with brain cancer.

John Huguenard
Professor of Neurology and Neurological Sciences (Neurology Research), of Neurosurgery (Adult Neurosurgery) and, by courtesy, of Molecular and Cellular Physiology
Current Research and Scholarly InterestsWe are interested in the neuronal mechanisms that underlie synchronous oscillatory activity in the thalamus, cortex and the massively interconnected thalamocortical system. Such oscillations are related to cognitive processes, normal sleep activities and certain forms of epilepsy. Our approach is an analysis of the discrete components (cells, synapses, microcircuits) that make up thalamic and cortical circuits, and reconstitution of components into in silico computational networks.

Siddhartha Joshi, PhD
Senior Research Scientist, Neurosurgery
BioI am a neuroscientist with over 20 years of experience in empirical, hypothesis-driven research. My knowledge and expertise cover a wide range of topics and methods within systems neuroscience including sensory perception, neurophysiology and neuroanatomy, eye-movements and pupillometry. My research is focused on how the brain represents and uses sensory information to drive goal-directed behaviors and in exploring how intrinsic neuromodulatory systems influence the neural circuits that drive such behaviors. At Stanford, I am looking to channel my experience towards studying human neural signals that underlie computations governing pain and attention.
My work thus far [1-4] supports the idea that there is a need for simultaneous measurements of behavior, brain state and large-scale cortical activity to understand how the brain’s circuits: (i) are modulated by ascending sympathetic activation and (ii) provide top-down control of descending sympathetic control. These are technically challenging experiments [3,4] that have thus far largely been explored in animal models. My current goal is to leverage opportunities to directly measure human brain activity via electrodes implanted for monitoring epilepsy. Towards this end, I will use state-of-the-art neurophysiological, behavioral, pupillometric techniques combined with quantitative analyses.

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. -

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. -
