Bradford Parkinson
Edward C. Wells Professor in the School of Engineering, Emeritus
BioProfessor Bradford Parkinson was the Chief Architect for GPS, and led the original advocacy for the system in 1973 as an Air Force Colonel. Gaining approval, he became the first Director of the GPS Joint Program Office and led the original development of spacecraft, Master Control Station and 8 types of User Equipment. He continued leadership of the Program through the extensive test validation Program, including being the Launch Commander for the first GPS satellite launches. This original deployment of GPS demonstrated comfortable margins against all PNT (Positioning, Navigation, and Timing) requirements.
Earlier in his career, he was a key developer of a modernized AC-130 Gunship, introduction of which included 160 hours of combat missions. He was an instructor at the USAF Test Pilot School. In addition he led the Department of Astronautics and Computer Science at the US Air Force Academy. He retired from the US Air Force as a Colonel.
He was appointed a Professor at Stanford University in 1984, after six years of experience in industry. At Stanford University, he led the development of many innovative applications of GPS, including:
1.Commercial aircraft (Boeing 737) blind landing using GPS alone,
2.Fully automatic GPS control of Farm Tractors on a rough field to an accuracy of 2 inches,
3.Pioneering the augmentation to GPS (WAAS) that allows any user to achieve accuracies of 2 feet and very high levels of integrity assurance.
He has been the CEO of two companies, and serves on many boards. He is the editor/author of the AIAA Award winning 2 Volumes: “GPS Theory and Applications” and is author or coauthor of over 80 technical papers.
Among his many awards is the Draper Prize of the National Academy of Engineering, considered by some to be the “Engineering Nobel”. -
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.

Preethy Parthiban
Postdoctoral Scholar, Neonatal and Developmental Medicine
BioMy research centers on how the innate immune system shapes tissue remodeling in health and disease. During my PhD, I uncovered a key role for resident macrophages in driving cardiac fibrosis, identifying a macrophage-derived chemokine that directly activates cardiac fibroblasts. Building on this foundation, my postdoctoral work at Stanford focuses on neutrophil–macrophage crosstalk in disrupted alveolarization in neonatal mice and patients. By integrating cellular, molecular, and translational approaches, I aim to define how innate immune pathways orchestrate extracellular matrix remodeling. Ultimately, my goal is to identify critical therapeutic targets that improve outcomes in ECM-related diseases.

Anca M. Pasca, MD
Assistant Professor of Pediatrics
Current Research and Scholarly InterestsI am a physician-scientist, neonatologist, and stem cell biologist whose research focuses on understanding mechanisms of human brain development, neuroinflammation, and neurological injury using patient-derived stem cell models.
I was among the early pioneers of three-dimensional human cortical organoid technologies and contributed to development of foundational protocols for generating region-specific human brain organoids from pluripotent stem cells. My work helped establish the feasibility of modeling human brain development and disease using stem cell-derived tissues and has contributed to the widespread adoption of organoid technologies across neuroscience, regenerative medicine, and translational research.
A major focus of my laboratory is the development of increasingly sophisticated multicellular organoid and assembloid systems that incorporate diverse neuronal and glial populations to model complex human brain circuitry and disease processes. We integrate stem cell biology, organoid engineering, CRISPR-based genome editing, single-cell transcriptomics, epigenomics, high-content imaging, and computational approaches to identify disease mechanisms and therapeutic targets. These technologies have been applied to studies of hypoxic brain injury, 22q11.2 deletion syndrome, Trisomy 21 (Down Syndrome), Trisomy 18, narcolepsy, Alzheimer's and Parkinson's Disease. -
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 and Senior Fellow, by courtesy, at the Hoover Institution
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. -
