Brad Zuchero, PhD  ||  Assistant Professor

Dr. J. Bradley Zuchero is an Assistant Professor in the Department of Neurosurgery, Stanford University School of Medicine. Brad has a longstanding interest in how cells in the brain interact to build a functional nervous system, regulate its function in adults, and how these interactions are perturbed in disease.

Brad grew up in the woods of Pennsylvania, becoming interested in science at a young age with the encouragement of his teacher parents. He majored in biology at Vassar College, where he first fell in love with research. Brad did his Ph.D. work with Dr. Dyche Mullins at UCSF, discovering and characterizing a novel protein that builds actin filaments in cells. In his postdoctoral work with Dr. Ben Barres at Stanford, he brought his expertise in cell biology to the study of how oligodendrocytes form myelin, with the goal of understanding why myelination commonly fails in diseases like multiple sclerosis (MS).

While working with Dr. Barres, Brad discovered that formation of myelin in the central nervous system occurs by a surprising and seemingly paradoxical mechanism: the actin cytoskeleton that is required for most cells to change shape and move is taken apart at the start of myelination. Understanding this mechanism, and testing whether it is perturbed in diseases affecting myelination is now a major research goal of his lab. Since starting in 2017, his lab has created a suite of novel genetic tools for perturbing actin in oligodendrocytes or any eukaryotic cell type—and is now using them to probe mechanisms of myelination. Recently his lab expanded its cell biology focus to ask how new membrane is added to power myelination, and discovered that exocytosis by the SNARE proteins Vamp2 and Vamp3 is required for myelin formation during development. In collaboration with Justin Du Bois's lab (Stanford Chemistry), the lab also discovered a signal that myelinating glia secrete to help neurons "come online" during development (Kantarci, Elvira, et al.). Brad hopes that work in his lab will contribute to cures for MS, Alzheimer's disease, and other diseases of the nervous system.

Brad has received numerous awards for his work including being named the Covert-Matera Families Endowed Faculty Scholar in 2023, the Beckman Young Investigator Award, McKnight Scholar Award, Harry Weaver Neuroscience Scholar Award, Koret Early Career Faculty Development Award, a Career Transition Award from the National MS Society, a Life Sciences Research Foundation postdoctoral fellowship, the Discovery Science Award and Pioneer Award from the Myelin Repair Foundation, and a Research Award from the Marine Biological Laboratory in Woods Hole. His lab also acknowledges support from the NIH (NINDS R01 and R21, NIA R21), a Stanford ADRC Developmental Grant, and additional grants from the Ludwig Family Foundation, Sanofi iAwards, and philanthropic support.

Some of his best ideas have come while cycling, running, or hiking around Northern California with his family.


Husniye Kantarci, PhD  ||  Postdoctoral fellow
Husniye is a Berry Postdoctoral Fellow in the Zuchero lab, and was also a winner of a 2017 Stanford ChEM-H Postdocs at the Interface seed grant and a 2017 Stanford School of Medicine Dean's Postdoctoral Fellowship. She is very interested in discovering the signals that enable the communications between glial cells and neurons, and understanding how these signals regulate neural function and myelination in the nervous system. Husniye attended Boğaziçi University in Istanbul, Turkey and majored in Molecular Biology and Genetics. She became fascinated with neural development during her undergraduate work and joined Dr. Bruce Riley’s lab at Texas A&M University for doctoral studies to study the genes and signaling pathways that regulate development of the inner ear neurons. During her PhD, Husniye characterized the signaling pathways that control formation, migration, and differentiation of inner ear neurons and discovered novel genes and mechanisms that govern inner ear neurogenesis. During her postdoctoral work, she is hoping elucidate novel pathways that regulate the interactions between the cells of the nervous system and characterize the role of disruptions in pathways in diseases of the brain. Husniye plans to power her postdoctoral work with hiking, cycling, climbing and running the wonderful trails of California.

Kathryn Wu  ||  MD-PhD Student
Kathryn is a student in the Medical Scientist Training Program, and a 2020 Wu Tsai Neurosciences Institute Stanford Interdisciplinary Graduate Fellows. She is interested in understanding the process of myelination and how it goes awry in disease. Kathryn first fell in love with biology during her undergraduate training at Swarthmore College, where she started out studying invasive species and soil respiration in the Crum Woods with Dr. Jose-Luis Machado. She eventually found her way to an air conditioned lab at the University of Pennsylvania, where she studied epigenetic changes in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) under Dr. Edward Lee. After finishing college, Kathryn joined Dr. Robert Baloh's lab at Cedars Sinai Medical Center, where she worked on developing and characterizing cellular models for ALS and FTD . Outside of lab and class, Kathryn enjoys going to bible study, climbing rocks both indoors and outdoors, and attempting to dance west coast swing.

Madeline Cooper  ||  MD-PhD Student
Madeline is a student in the Medical Scientist Training Program, and a 2020 Stanford Bio-X Graduate Fellow. She is excited to spend her PhD combining her background in biomaterials with her love of the best organ (the brain!) to study oligodendrocytes in physiologic microenvironments. Her goal is to shed light on the biophysical forces that drive myelin formation. Madeline's fascination with understanding how cells respond to their physical environments started during her undergraduate studies at Harvard where she researched mechanotransduction in the Mooney Laboratory for Cell and Tissue Engineering. She then worked at Draper in Cambridge, MA developing microfluidic in vitro organ models before coming to Stanford. If you can't find Madeline in the lab she's probably out pursuing one of her other passions: mentoring younger students, running, cooking, dancing, or doing any outdoor activity that lets her explore California!

Graham Jones, Ph.D.  ||  Postdoctoral fellow
Graham is a postdoctoral research fellow. He is interested in studying the impact of disease-linked genes on myelination. Graham attended the University of Washington, where he majored in Biology: Physiology and Psychology. While in Seattle, he was an undergraduate research assistant and lab technician with Dr. Sheri Mizumori studying the role of ventral tegmental area activity on hippocampal physiology. He then worked as a research scientist/engineer helping Dr. Larry Zweifel establish his lab while investigating how dysfunctional dopaminergic signaling affects neural processing in the amygdala. He then moved to the University of Michigan and earned his Ph.D. in Neuroscience with Dr. Malcolm Low, where he studied the impact of proopiomelanocortin-deficiency, obesity, and weight loss in motivated behavior. Graham enjoys exploring new places with his fiancé Caitlin and dog Penny, homebrewing, golfing, trivia, and playing basketball and softball.

Mable Lam, Ph.D.  ||  Postdoctoral fellow
Mable is a Helen Hay Whitney postdoctoral research fellow in the lab, also supported by a Wu Tsai Neurosciences Institute Postdoctoral Scholar Award, a Stanford ADRC REC Scholars Fellowship, and previously by a Vision T32. She is interested in understanding cellular mechanisms that mediate myelination. She did her Ph.D. at UCSF with Peter Walter to study how cells respond to protein folding stress in the secretory pathway (ER stress). She discovered that misfolded proteins in the secretory pathway are detected by a death receptor to activate apoptosis during unresolved stress. She is now applying her background in secretory trafficking to elucidate mechanisms of membrane addition during myelination. In 2022, she published a co-first author paper with Koji Takeo revealing the importance of exocytosis for myelination (Lam, Takeo et al. 2022 Nature Communications). Outside of the laboratory, she enjoys Olympic weightlifting and breakfast foods.

Maya Weigel  ||  PhD Student
Maya is a graduate student in the Stem Cell Biology and Regenerative Medicine PhD Program. In the Zuchero Lab, she is interested in studying how oligodendrocytes contribute to central nervous system pathology in neurodegenerative diseases. Maya first became fascinated with the nervous system during her undergraduate studies in Biology at Pomona College where she studied the role of chondroitin sulfate proteoglycans in Drosophila central nervous system development. She subsequently moved back to the Bay Area to work as a research associate in Dr. Ben Barres’s lab at Stanford, where she studied neurotoxic reactive astrocytes. Most importantly, Maya’s work in the Barres Lab drew her into the world of glial biology, and she hasn’t looked back. Outside of the lab, Maya enjoys running (and does it a lot), growing plants and turning them into salads, eating soft-serve ice cream, and basking in the Bay Area sunshine.

Khanh Tran  ||  Undergraduate student
Khanh is a Stanford University undergraduate student. Khanh first developed a passion for biology in high school, leading her to reach out to the Zuchero Lab in hopes of pursuing her newfound interest through an internship. Beginning the summer after her sophomore year, she interned under Dr. Husniye Kantarci--a mentor who, along with Brad, taught her nearly everything she now knows and loves about glia. Though her interest in biology isn’t limited to just one field--especially after spending a fascinating summer in the Bendall Lab where she studied hematopoietic cancers under Dr. Albert Tsai--she hopes to one day pursue a Ph.D. in neuroscience. When she’s not procrastinating on schoolwork or working at the bench, Khanh enjoys cross country running, exploring the great outdoors with her friends, and making lattes as a part-time barista at the nearby Big Basin Cafe.
