  • Sundari Chetty

    Sundari Chetty

    Assistant Professor, Psychiatry and Behavioral Sciences

    Current Research and Scholarly InterestsThe Chetty lab is interested in understanding the mechanisms underlying neurodevelopmental and psychiatric disorders, such as autism spectrum disorder and schizophrenia. In particular, our group has been investigating the mechanisms underlying brain overgrowth or undergrowth in these disorders using human induced pluripotent stem cell (hiPSC) technology. Changes in brain size often precede clinical symptoms, suggesting that understanding the underlying mechanisms regulating brain overgrowth or undergrowth could provide a window of opportunity for intervention or mitigation of symptoms.

    Using hiPSCs from idiopathic patients as well as those with known genetic variations, we generate iPSC-derived cortical neural and oligodendroglial cells to investigate changes at the cellular, functional, and mechanistic levels using a broad range of techniques from RNA sequencing, genome editing, to functional assays in in vitro and in vivo models. The overarching goal of our research program is to identify novel therapeutic targets based on these mechanistic insights.

  • Gheorghe Chistol

    Gheorghe Chistol

    Assistant Professor of Chemical and Systems Biology

    Current Research and Scholarly InterestsResearch in my laboratory is aimed at understanding how eukaryotes replicate their DNA despite numerous challenges (collectively known as replication stress), and more generally – how eukaryotic cells safeguard genome integrity. Specifically, we are investigating: (i) mechanisms that regulate the activity of the replicative helicase during replication stress, (ii) mechanisms that control the inheritance of epigenetic information during replication, and (iii) mechanisms of ubiquitin-mediated regulation of genome maintenance. We utilize single-molecule microscopy to directly image fluorescently-labeled replication factors and track them in real time in Xenopus egg extracts. I developed this system as a postdoctoral fellow, and used it to monitor how the eukaryotic replicative helicase copes with DNA damage. We plan to further extend the capabilities of this platform to directly visualize other essential replication factors, nucleosomes, and regulatory post-translational modifications like ubiquitin chains. By elucidating molecular mechanisms responsible for maintaining genome stability, we aim to better understand the link between genome instability and cancer, and how these mechanisms can be harnessed to improve disease treatment.

    BioDr. Choi is an interventional and forensic neuropsychiatrist on the Stanford faculty. He received his MD/PhD at UC-San Diego as part of NIH's Medical Scientist Training Program. He received his PhD degree in Neuroscience for work done at the Salk Institute in neural development.

    Dr Choi is the founding director of Stanford's Forensic Psychiatry Fellowship Program, the first neurolaw-focused forensic fellowship in the world. As a forensic psychiatrist, Dr. Choi specializes in neurolaw, an emerging interdisciplinary field that studies the use and misuse of neuroscience-based evidence in the courtroom. His research interests include the use of functional brain imaging to discern mental states (e.g. lie detection, pain assessment), and the neural basis for moral decision making (e.g. defects in moral reasoning brain centers giving rise to psychopathy). A central question he considers is: how do advances in our knowledge of the neural basis of behavior change perceptions of how offenders should be punished? He has testified as a court-appointed expert, as well as for the prosecution and defense, in many high-profile and complex cases involving psychiatric, neurologic, medical, and medication-related legal claims. Dr. Choi is an active educator, providing seminars to students, attorneys, judges, neuroscientists and clinicians on the importance and relevance of neuroscience and the law.

    Dr. Choi’s clinical interests include neuromodulatory approaches to treat psychiatric illness, such as the use of transcranial magnetic stimulation (TMS) to treat major depression. He is part of the interventional psychiatry group of Stanford Medicine, conducting clinical work and research to advance the power, precision, and scope of neuromodulation.

    Dr. Choi is an experienced public speaker, and has given a number of talks to lay and professional audiences on neurolaw, the neuroscience of psychopathy, and the neuroscience of moral decision-making. He is a featured TEDx speaker on the topic "Can Neuroscience Eradicate Psychopathy?"

She is Director of Pediatric Craniofacial and Airway Orthodontics and Dental Sleep Medicine in the Department of Surgery and Director of Pediatric Craniofacial and Airway Orthodontic Fellowship at Lucile Packard Children's Hospital Stanford. She is also a Faculty Fellow of the Stanford Byers Center for Biodesign.

    After graduating from Seoul National University with a combined degree in Natural Sciences and Dental Surgery in 2002, Dr. Choo received her Dental Medicine degree from the University of Pennsylvania. She completed her orthodontic residency and Masters in Science degree program at the University of Alabama in Birmingham. Following her Craniofacial Fellowship at the Clinical Center of the National Institutes of Health (NIH) / National Institute of Dental and Craniofacial Research (NIDCR), Dr. Choo was recruited as a full-time faculty member at the University of Pennsylvania and The Children’s Hospital of Philadelphia. Dr. Choo joined the faculty of Stanford University School of Medicine in 2016. Dr. Choo is a board-certified craniofacial orthodontist by American Board of Orthodontics since 2008 and became a diplomate of the American Board of Dental Sleep Medicine in 2021.

    Dr. Choo’s areas of expertise are non-surgical airway management and facial reconstruction for newborns with cleft and/or Robin Sequence in the Neonatal Intensive Care Unit. Her treatments utilize simple custom-fabricated orthodontic devices to establish a healthy environment to correct neonatal orofacial abnormalities with great respect for natural growth potential of each neonate. She also practices the full scope of pediatric obstructive sleep apnea management as well as orthodontics and dentofacial orthopedics for patients with cleft and craniofacial abnormalities in a multi-disciplinary clinical setting.

    Assistant Professor of Pediatrics (Endocrinology) and, by courtesy, of Chemical and Systems Biology

    Current Research and Scholarly InterestsOur research program integrates concepts of chemical biology, protein engineering and structure biology to design new therapeutic leads and generate probes to study biological processes. A key focus of our lab is insulin, an essential hormone in our body to reduce blood glucose levels. We generate synthetic libraries of insulin analogs to select for chemical probes, and investigate natural insulin molecules (e.g. from the venom of fish-hunting cone snails!) to develop novel therapeutic candidates. We are especially interested in using chemical and enzymatic synthesis to create novel chemical entities with enhanced properties, and leverage the strong expertise of our collaborators to apply our skill sets in the fields of cancer biology, immunology and pain research. Our ultimate goal is to translate our discovery into therapeutic interventions in human diseases.
