Sneha Ramakrishna
Assistant Professor of Pediatrics (Hematology/Oncology)
BioSneha Ramakrishna obtained her B. A. from the University of Chicago and her M.D. from the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University. In medical school, through the Howard Hughes Medical Research Scholar Award, she joined Dr. Crystal Mackall’s laboratory, where she designed and developed various GD2 CAR-Ts and tested them in preclinical models. During her residency training in Pediatrics at the Children’s Hospital of Philadelphia, she cared for some of the first patients treated with CD19 CAR T cells, learning the power of this therapy first-hand. During her fellowship in Pediatric Hematology/Oncology at the Johns Hopkins/National Cancer Institute combined program, she worked with Dr. Terry Fry. She evaluated the mechanism of CD22 CAR T cell relapse in patients by developing an antigen escape model and establishing a deeper understanding of the effects of antigen density on CAR-T phenotype, expansion, and persistence (Fry…Ramakrishna…Mackall Nat Med, 2018; Ramakrishna, et al., Clinical Cancer Research, 2019). Since arriving at Stanford, Dr. Ramakrishna leads an interdisciplinary team that designs, develops, and successfully implements a robust correlative science platform for our novel CAR-T therapies. Analyzing patient samples from our first-in-human GD2 CAR-T trial (NCT04196413) treating a universally fatal cancer, diffuse midline glioma (DMG), we identified that intracerebroventricular CAR-T administration correlates with enhanced pro-inflammatory cytokines and reduced immunosuppressive cell populations in cerebrospinal fluid as compared to intravenous CAR-T administration (Majzner*, Ramakrishna*, et al., Nature 2022 *co-first authors). Her research program evaluates unique sets of patient samples using novel single-cell immune profiling to identify the drivers of CAR-T success or failure. Building on these findings, her team assesses approaches to enhance CAR-T efficacy and translate these findings to the clinic.
Clinically, Dr. Ramakrishna cares for children with solid tumors and treats hematologic, solid, and brain tumor pediatric patients with CAR T cell therapies in the Cancer Cellular Therapies program. -

Ashwin Ramayya, MD, PhD
Assistant Professor of Neurosurgery
BioDr. Ramayya is an assistant professor in the Department of Neurosurgery. He specializes in the treatment of patients with chronic pain, movement disorders, epilepsy, and traumatic brain injury. His research program will focus on understanding brain mechanisms underlying pain experience and how to alleviate pain using brain stimulation.
Dr. Ramayya specializes in neuromodulation, including deep brain stimulation (DBS), spinal cord stimulation, MRI-guided laser therapy, and focused ultrasound. Dr. Ramayya obtained his MD and PhD from the University of Pennsylvania, where he also completed his neurosurgery residency and a fellowship in stereotactic and functional neurosurgery.
His research efforts have identified neural substrates underlying learning, memory, and decision-making using computational behavioral modeling, neurophysiology, and neuroimaging.
Dr. Ramayya has published in numerous peer-reviewed journals, including the Journal of Neuroscience, NeuroImage, and Cerebral Cortex. He has also presented his work at national and international meetings, including those for the American Association of Neurological Surgeons and the Pan Philadelphia Neurosurgery Conference. -

Meghan Ramsey
Clinical Associate Professor, Medicine - Pulmonary, Allergy & Critical Care Medicine
BioDr. Meghan Ramsey is a Clinical Associate Professor in the Division of Pulmonary, Allergy, and Critical Care Medicine. She received her undergraduate degree from Lafayette College in Pennsylvania with a major in Neuroscience. She then attended Stanford University for medical school where she stayed to complete her internal medicine residency, and pulmonary/critical care fellowship. Her clinical time is split between the inpatient setting in the medical ICU and the ambulatory setting in Interventional Pulmonology with a focus on thoracic malignancies. Outside of her clinical time she has a dedicated commitment to teaching, serving as a mentor for residents and fellows, as well as leading as a co-director the pulmonary physiology course for medical students.
