Nicholas Wiessner Larsen, MD
Clinical Assistant Professor, Adult Neurology
BioDr. Larsen is a clinical assistant professor in the Department of Neurology, Division of Autonomic Disorders. He is a board-certified neurologist and a fellowship-trained specialist in neurophysiology and autonomics. He completed medical school at the University of Utah and neurology residency and fellowship at Stanford.
In his clinical practice, Dr. Larsen focuses on disorders of the autonomic nervous system (ANS). His research interest is in the long-term autonomic complications of COVID-19. He is the principal investigator of a study looking at post-COVID postural tachycardia syndrome.
Dr. Larsen’s research interests also include Global Health Neurology. Dr. Larsen helped establish the first stroke unit in Rwanda and is part of the American Academy of Neurology’s Refugees & Asylum Seekers Working Group.
He has co-authored articles for publication in Clinical Autonomic Research, Autonomic Neuroscience, Nature Climate Change, and elsewhere. He is a recipient of the American Academy of Neurology Medical Student Prize for Excellence as well as a member of the Alpha Omega Alpha Honor Medical Society. -
David Larson
Professor of Radiology (Pediatric Radiology)
On Partial Leave from 01/15/2026 To 05/15/2026BioDavid B. Larson, MD, MBA, is Professor of Radiology (Pediatric Radiology) in the Department of Radiology at Stanford University. His career is focused on managing and improving complex sociotechnical healthcare systems to drive continuous operational improvement for the benefit of patients and clinicians. His research and leadership activities span the sociotechnical spectrum, from the development of process control systems that optimize CT radiation dose to transitioning the field of radiology from "peer review" toward "peer learning" to foster a more collaborative and constructive work environment.
He has founded and directed numerous improvement programs at Stanford and beyond, including Stanford’s Realizing Improvement through Team Empowerment (RITE) program, the Clinical Effectiveness Leadership Training (CELT) (program co-founder), Stanford Medicine's Improvement Capability Development Program (ICDP), and the Stanford Medicine Center for Improvement's (SMCI's) Advanced Course in Improvement Science (ACIS). He is also the founder and co-director of the American College of Radiology's (ACR's) Learning Network, its various Improvement Collaboratives, and the ImPower improvement training and project support program.
Dr. Larson served for over 10 years in various senior leadership roles in the Stanford Department of Radiology, including Associate Chair for Performance Improvement, Vice Chair for Education and Clinical Operations, Executive Vice Chair, and Acting Chair. He currently serves as the Director of the Stanford Radiology AI Development and Evaluation (AIDE) Lab. He also serves as the Medical Director of Performance Improvement at Stanford Health Care.
Dr. Larson has applied his experience to advance the thinking and application of systematic improvement methods in the field of radiology. He is the founder and program chair for the annual Radiology Improvement Summit held annually at Stanford, which began in 2016. He serves on the Board of Trustees of the American Board of Radiology, overseeing quality and safety, and on the Board of Chancellors for the American College of Radiology as the chair of the ACR's Commission on Quality and Safety.
Prior to his position at Stanford, Dr. Larson was the Janet L. Strife Chair for Quality and Safety in Radiology and a faculty member of the James M. Anderson Center for Health Systems Excellence at Cincinnati Children’s Hospital in Cincinnati, Ohio. He holds MD and MBA degrees from Yale University and completed his pediatric internship and radiology residency and fellowship at the University of Colorado Health Sciences Center in Denver, Colorado. Dr. Larson practices clinically at Lucile Packard Children's Hospital at Stanford. -

Amira Latif Hernandez
Instructor, Adult Neurology
BioAmira obtained her Ph.D. in Neuroscience from the KU Leuven, Belgium, in summer 2017. During her doctoral studies, she used clinically valid tests of murine cognition, neuronal plasticity measures in hippocampal and cortical slices, brain lesion methods, pharmacological applications and resting state functional magnetic resonance imaging to characterize the pathophysiology of novel mouse models of Alzheimer’s disease (AD). One of her most gratifying contributions was the development of a new electrophysiology tool to assess synaptopathies, and the establishment of long-term synaptic plasticity from prefrontal cortex of APP knock-in mice. In Autumn 2017, she moved to Dr. Longo’s lab at the Stanford School of Medicine, where she investigates signaling pathways involved in synaptic degeneration. During 3 years of postdoctoral work, she established a multi-electrode array system with eight independent recording chambers that allows high-throughput analyses of multiple long-lasting forms of synaptic plasticity. She also gained experience in RNA-sequencing, molecular biochemistry, signaling mechanisms, target validation and drug development strategies for AD. In October 2020, Amira has been appointed as an Instructor in Neurodegenerative Disease Research, in the Longo lab, to help develop improved and more powerful approaches that will better reveal key synaptic mechanisms and candidate modules associated with neuroplasticity and affected in AD mouse models, by identifying activity-dependent gene expression signatures.
