    Postdoctoral Research Fellow, Anesthesiology, Perioperative and Pain Medicine

    Bio For over a decade my research career as a systems neuroscientist has been centered around measuring the brain in different states of consciousness using electrophysiology. Two ways to study conscious transitions empirically are by investigating the brain during sleep and while under anesthesia. I spent my doctoral and early postdoctoral work studying how sleep improves learning and memory at the neural network level. I characterized a phenomenon known as replay (when networks in the brain rehearse previous experiences offline) in a novel visual area. I continued research on replay in my early postdoctoral work in the hippocampus (an area important for spatial navigation as well as memory formation). My work centered around trying to understand how different hippocampal replay trajectories are selected by reward centers in the brain for future behavioral action. 

    I am now interested in studying the brain activity associated with anesthetics to broaden my understanding of brain states that exhibit altered consciousness. In fact, the brain shares similar electrophysiological activity during sleep with some anesthetic transitions. With anesthetics, though one is able to compare how different anesthetic agents interact with different neuromodulatory systems to cause similar behavior outcomes (i.e. sedation and unconsciousness). My current project is to explore and evaluate different computational approaches to quantifying anesthetic depth using electroencephalography. A thorough characterization of the brain activity associated with loss of consciousness during anesthesia is of critical importance to better monitor patients undergoing anesthesia. I am excited by this new opportunity to meld my previous expertise in systems neuroscience electrophysiology with clinical and translational work. It has been a long-term aspiration of mine to do research that will have direct applications to improving human health. 

  • Koray Ertan

    Koray Ertan

    Postdoctoral Research Fellow, Radiological Sciences Laboratory

    Bio Koray Ertan received his BSc degree in the Department of Electrical and Electronics Engineering at Bilkent University, Turkey. He completed his PhD in the same department under the supervision of Prof. Ergin Atalar. During his PhD, he worked as a researcher at National Magnetic Resonance Research Center (UMRAM) of Turkey. His thesis study is the development of novel magnetic resonance imaging (MRI) technologies such as gradient array systems for increasing diagnostic quality of the MR images, reducing the specific absorption rate and scan time.

    He joined Prof. Brian Rutt's group as a postdoctoral researcher in April 2019. Later, he was also affilated as a MINDED postdoctoral fellow in June 2019. As part of the MINDED program, his current research focuses on a system for modulating the permeability of the blood brain barrier using focused radio frequency heating generated from ultra-high field MRI transmit coils for enhanced treatment of neurodevelopmental disorders with nanomedicines. Additionally, his research interest mostly includes MRI technolgies such as RF pulse design, gradient systems, field monitoring, multi-coil gradient and shim arrays.

  • Neir Eshel, MD, PhD

    Neir Eshel, MD, PhD

    Instructor, Psychiatry and Behavioral Sciences

    Bio Dr. Eshel (he/him/his) is a psychiatrist and instructor in the Department of Psychiatry & Behavioral Sciences at Stanford University School of Medicine.

    His clinical focus is the full-spectrum mental health care of sexual and gender minorities, with particular interest in depression, anxiety, and the complex effects of trauma in this population. He works in collaboration with other primary care and mental health providers at the new Stanford LGBTQ+ program.

    His research interests include the use of optogenetic, electrophysiological, neuroimaging, and behavioral approaches to probe the neural circuits of reward processing, decision making, and social behavior. He recently won a multi-year grant from the National Institute of Mental Health to study the neural circuits of frustration and aggression.

    Dr. Eshel has published articles on topics such as the role of dopamine in learning, the neuroscience of irritability, LGBTQ health, reward and punishment processing in depression, behavioral predictors of substance use among adolescents, and the mechanism of transcranial magnetic stimulation. His work has appeared in Nature, Science, Nature Neuroscience, Annual Review of Neuroscience, JAMA, JAMA Psychiatry, Neuropsychopharmacology, Proceedings of the National Academy of Sciences, and Journal of Neuroscience. He is also the author of the book Learning: The Science Inside, a publication of the American Association for the Advancement of Science.

    He has delivered presentations on anger expression in patients with PTSD, the neural circuitry of learning, dopamine prediction errors, and LGBTQ-related topics at meetings of the American College of Neuropsychopharmacology, Society of Biological Psychiatry, and Association of American Medical Colleges, among others. He is also an associate editor of the Journal of Gay and Lesbian Mental Health, and an ad-hoc reviewer for numerous publications including Science, JAMA Psychiatry, Biological Psychiatry, and Current Biology.


    Dr. Eshel has won honors for his scholarship and advocacy, including the Marshall Scholarship, the Outstanding Resident Award from the National Institute of Mental Health, the Science and SciLifeLab Grand Prize for Young Scientists, and the National LGBT Health Achievement Award.

    He is a member of the American Psychiatric Association, Society of Biological Psychiatry, Association of Gay & Lesbian Psychiatrists, Society for Neuroscience, and other professional associations. He is also an advocate for LGBTQ rights, recently serving as the LGBTQ Chair of the Stanford Graduate Medical Education Diversity Committee.

    Prior to Stanford, Dr. Eshel trained and conducted research at the National Institutes of Health, Princeton University, the World Health Organization, University College London, and Harvard University.
