Dr. David Raleigh received his undergraduate degrees from the University of California Berkeley, and his medical and doctoral degrees from the University of Chicago. Dr. Raleigh completed his residency training in the Department of Radiation Oncology at UCSF, and he trained as a postdoctoral scholar with Dr. Jeremy Reiter in the Department of Biochemistry at UCSF, with whom he collaborates regularly. He is a member of the faculty in the UCSF Departments of Radiation Oncology and Neurological Surgery, where he is specialized in the treatment and investigation of central nervous system tumors in adult and pediatric patients. In the laboratory, Dr. Raleigh is a Principal Investigator in the UCSF Brain Tumor Center and uses mouse genetics, genomics, cell biology, biochemistry, molecular biology, cerebral organoids, single-cell techniques, and pharmacology to study the genomic, biochemical, and cellular drivers of cancer predisposition syndromes. Dr. Raleigh is also the director of the UCSF Brain Tumor Center Preclinical Core, a longstanding facility within the Department of Neurological Surgery specialized in organoid and patient-derived xenograph models of brain cancer. When he's not in the lab... or thinking about the lab... or writing things for the lab... David loves spending time with his wife, 2 children, and dog at their home in San Francisco, where he enjoys cooking and starting longingly at the surfboards and road bikes he no longer has time to use.

Current Lab Members

Charlotte Eaton is a Postdoctoral Scholar in the department of Neurological Surgery. She received her PhD from the University of Birmingham (UK) in Molecular Biology and Biochemistry. In the Raleigh Lab, Charlotte is focussed on utilizing biochemistry, molecular and cell biology techniques, and CRISPR technology to understand the molecular mechanisms that drive Merlin mutated meningiomas.

Vikas Daggubati is an MD/PhD student in the Biomedical Sciences program at UCSF. As a graduate student in the Raleigh lab, he is studying Hedgehog signaling and ciliary biology. He has shown that resistance to CDK6 inhibition can develop through repression of ribosomal genes, thereby generating ER stress and activating the unfolded protein response to upregulate sterol lipids that sustain oncogenic Hedgehog signaling. Vikas is currently performing ciliary proteomic experiments to answer fundamental questions regarding ciliary trafficking of key Hedgehog proteins. When he’s not in lab, Vikas enjoys anything involving the outdoors and cooking!

John Liu is a resident physician and scientist in the Department of Radiation Oncology at UCSF. Joint with the group of Luke Gilbert, he is developing functional genomics approaches to dissect the molecular mechanisms of brain tumor pathogenesis and specifically — resistance to radiation therapy. He completed his MD and PhD at UCSF in the laboratory of Daniel Lim, where he studied the function of long non-coding RNAs in neural development and in brain tumors, pioneering the use of genome-scale CRISPR interference toward lncRNA biology.

After graduating from Duke University in 2017 with a B.S. in Biology, she spent three years studying photoreceptor biochemistry with a focus in molecular proteomics with the Arshavsky lab at the Duke Medical Center. As a member of the Raleigh lab, she is currently focused on employing biochemistry, cell biology, and proteomic techniques to elucidate the molecular players that drive meningioma pathology. Outside of lab, Addie spends her time backpacking, skiing, cooking, and spending time with her (amazing) pup Kona.

Jake Young is a neurosurgery resident at the University of California, San Francisco with an interest in neurosurgical oncology and immunotherapy. He is a graduate of Duke University and the University of Chicago Pritzker School of Medicine, respectively. His project in the Raleigh Lab aims to dissect tumor-mediated mechanisms of immunotherapy resistance with single-cell techniques and reprogram this immunosuppressive glioblastoma microenvironment with gene therapy via surgically mediated delivery strategies like convection enhanced delivery. He partners his laboratory work with clinical research exploring how to optimize functional outcomes and minimize complications after surgery for intrinsic brain tumors with direct electrical stimulation and brain mapping, where he works closely with mentors Shawn Hervey-Jumper MD, Manish Aghi MD PhD, and Mitchel Berger MD.

Eze Goldschmidt is an Assistant Professor in the UCSF Department of Neurological Surgery who cares for patients with brain, skull base and pituitary gland tumors. His clinical experience treating patients with skull base tumors has led him to questions related to the biology of meningioma biology and the possibility of medically treating patients that have exhausted all surgical treatments. Specifically, Eze seeks to understand how meningiomas interact with the skull and, contrary to most tumors, induce bony deposition. A proud member of the Latinx community, Eze earned his medical degree and doctorate at the University of Buenos Aires in Argentina, where he studied the regeneration of human dura (the outermost membrane covering the brain). He completed a residency in neurosurgery and a fellowship in skull base surgery at the University of Pittsburgh Medical Center. At the Karolinska Institute in Sweden, he completed a postdoctoral surgical fellowship in neuroplasticity (the ability of the brain's neural pathways to change in response to stimulation ranging from new information to injury). In his free time, Eze enjoys walking his dog, petting his dog, and watching movies with his dog (who we believe enjoys those activities as well).

Arjun Mehta is a fourth-year undergraduate student studying Integrative Human Biology and Spanish Language at UC Berkeley. Arjun’s previous research experiences have included amphibian genetics, museum specimen preparation, genome sequencing, non-photochemical quenching, and knocking out genes in plants. Arjun’s passion for genetics has led him to the Raleigh Lab, where he will be working with Tim to study the molecular signatures driving Schwann cell-derived tumors via mouse genetics and cell culture screenings. Outside of the lab, Arjun loves to play Pokémon, draw amphibians, stare at pugs, and study languages (Hindi, Urdu, & Spanish)!
