Robertson Parkman
Other Teaching Staff-Hourly, Pediatrics - Stem Cell Transplantation
BioMy principal research interests have been the assessment of the immunological consequences of hematopoietic stem cell transplantation including both acute and chronic graft versus host disease and immune reconstitution and the use of hematopoietic stem cell transplantation to treat genetic diseases. My laboratory was the first to suggest that chronic graft versus host disease was an autoimmune disease directed at histocompatibility antigens shared by donors and recipients. The observation leaded to the assessment of the role of thymic dysfunction in the pathogenesis of chronic graft versus host disease. As a pediatric immunologist I have investigated the role of hematopoietic stem cell transplantation initially in the treatment of primary immune deficiency diseases and later the treatment of metabolic diseases, which lead to my involvement in the early gene transfer clinical trials.

Jane Parnes
Professor of Medicine, Emerita
Current Research and Scholarly InterestsThe lab is studying the mechanisms controlling B cell responsiveness and the balance between tolerance and autoimmunity. B cells deficient in CD72 are hyperresponsive to stimulation through the B cell receptor. We are examining the alterations in B cell signaling in these B cells and the mechanisms by which CD72 deficiency partially abrogates anergic tolerance. We hope to learn how deficiency in CD72 leads to spontaneous autoimmunity and increased susceptibility to induced autoimmune disease.

Shyon Parsa
Affiliate, Department Funds
Resident in MedicineBioShyon earned his B.S. in Biomedical Engineering from the Cockrell School of Engineering at the University of Texas - Austin, graduating with Honors. He completed coursework in Thermodynamics and Transport Phenomena in Living Systems at the Department of Applied Mathematics and Theoretical Physics at Cambridge University under Clare Hall fellow Dr. Kenneth Diller. After graduation, Shyon enrolled in medical school at UT Southwestern, and graduated with an M.D with Distinction in Research and as a member of the Alpha Omega Alpha (AOA) honor society.
He started his internal medicine residency at Stanford University Hospital in 2023. In 2024, he was awarded a Stanford Cardiovascular Institute Seed Grant for his project "An Artificial Intelligence Approach Utilizing Radiomic-Derived Calcium Features on Calcium Scoring CT (CAC-CT) in Cardiovascular Risk Stratification" (Co-PI). In 2025, he was selected for a Young Investigator Award from the National Lipid Association and named as an American Heart Association Early Career Investigator Award for Preventive Cardiovascular Medicine Research finalist. He is currently leading the NOTIFY-ASCVD trial alongside Co-PIs Fatima Rodriguez and Fahim Abbasi.
His interests include the use of AI in opportunistic coronary artery disease assessment, clinical integration of AI-based diagnostic algorithms through clinical trials, and preventive health advocacy through public policy. He plans to pursue a career in cardiology with a focus on advanced computational imaging techniques, medical device development, and advocacy both in his local communities and abroad. -
Julie Parsonnet
George DeForest Barnett Professor of Medicine, Emerita
Current Research and Scholarly InterestsI am an infectious diseases epidemiologist who has done large field studies in both the US and developing countries. We research the long-term consequences of chronic interactions between the human host and the microbial world. My lab has done fundamental work establishing the role of H. pylori in causing disease and understanding its epidemiology. Currently, our research dissects how and when children first encounter microbes and the long term effects of these exposures on health.

Anca M. Pasca, MD
Assistant Professor of Pediatrics
On Partial Leave from 01/05/2026 To 04/19/2026Current Research and Scholarly InterestsThe research focus of the lab is to understand molecular mechanisms underlying neurodevelopmental disorders associated with premature birth, neonatal and fetal brain injury with the long-term goal of translating the lab’s findings into therapeutics. The research team employs a multidisciplinary approach involving genetics, molecular and developmental neurobiology, animal models and neural cells differentiated from patient-derived induced pluripotent stem (iPS) cells. In particular, the lab is using a powerful 3D human brain-region specific organoid system developed at Stanford (Nature Methods, 2015; Nature Protocols, 2018) to ask questions about brain injury during development.

Sergiu P. Pasca
Kenneth T. Norris, Jr. Professor of Psychiatry and Behavioral Sciences and Bonnie Uytengsu and Family Director of the Stanford Brain Organogenesis Program
Current Research and Scholarly InterestsA critical challenge in understanding the intricate programs underlying development, assembly and dysfunction of the human brain is the lack of direct access to intact, functioning human brain tissue for detailed investigation by imaging, recording, and stimulation.
To address this, we are developing bottom-up approaches to generate and assemble, from multi-cellular components, human neural circuits in vitro and in vivo.
We introduced the use of instructive signals for deriving from human pluripotent stem cells self-organizing 3D cellular structures named brain region-specific spheroids/organoids. We demonstrated that these cultures, such as the ones resembling the cerebral cortex, can be reliably derived across many lines and experiments, contain synaptically connected neurons and non-reactive astrocytes, and can be used to gain mechanistic insights into genetic and environmental brain disorders. Moreover, when maintained as long-term cultures, they recapitulate an intrinsic program of maturation that progresses towards postnatal stages.
We also pioneered a modular system to integrate 3D brain region-specific organoids and study human neuronal migration and neural circuit formation in functional preparations that we named assembloids. We have actively applied these models in combination with studies in long-term ex vivo brain preparations to acquire a deeper understanding of human physiology, evolution and disease mechanisms.
We have carved a unique research program that combines rigorous in vivo and in vitro neuroscience, stem cell and molecular biology approaches to construct and deconstruct previously inaccessible stages of human brain development and function in health and disease.
We believe science is a community effort, and accordingly, we have been advancing the field by broadly and openly sharing our technologies with numerous laboratories around the world and organizing the primary research conference and the training courses in the area of cellular models of the human brain.
