Maria Barna
Associate Professor of Genetics
Current Research and Scholarly InterestsOur lab studies how intricate control of gene expression and cell signaling is regulated on a minute-by-minute basis to give rise to the remarkable diversity of cell types and tissue morphology that form the living blueprints of developing organisms. Work in the Barna lab is presently split into two main research efforts. The first is investigating ribosome-mediated control of gene expression genome-wide in space and time during cellular differentiation and organismal development. This research is opening a new field of study in which we apply sophisticated mass spectrometry, computational biology, genomics, and developmental genetics, to characterize a ribosome code to gene expression. Our research has shown that not all of the millions of ribosomes within a cell are the same and that ribosome heterogeneity can diversify how genomes are translated into proteomes. In particular, we seek to address whether fundamental aspects of gene regulation are controlled by ribosomes harboring a unique activity or composition that are tuned to translating specific transcripts by virtue of RNA regulatory elements embedded within their 5’UTRs. The second research effort is centered on employing state-of-the-art live cell imaging to visualize cell signaling and cellular control of organogenesis. This research has led to the realization of a novel means of cell-cell communication dependent on a dense network of actin-based cellular extension within developing organs that interconnect and facilitate the precise transmission of molecular information between cells. We apply and create bioengineering tools to manipulate such cellular interactions and signaling in-vivo.

Christopher O. Barnes
Assistant Professor of Biology and, by courtesy, of Structural Biology
Current Research and Scholarly InterestsResearch in our lab is aimed at defining the structural correlates of broad and potent antibody-mediated neutralization of viruses. We combine biophysical and structural methods (e.g., cryo-EM), protein engineering, and in vivo approaches to understand how enveloped viruses infect host cells and elicit antigen-specific immune responses. We are particularly interested in the co-evolution of HIV-1 and broadly-neutralizing IgG antibodies (bNAbs), which may hold the key to the development of an effective HIV-1 vaccine. In addition, we are investigating antibody responses to SARS-CoV-2 and related zoonotic coronaviruses (CoV), with the related goal of developing broadly-protective immunotherapies and vaccines against variants of concern and emerging CoV threats.

Richard Baron, MD
Clinical Assistant Professor, Neurology & Neurological Sciences
BioDr. Baron is a board-certified, fellowship-trained neurologist in the Stanford Health Care Headache Clinic and the Vestibular Balance Disorders Program. He is also clinical assistant professor in the Department of Neurology & Neurological Sciences and, by courtesy, in the Department of Otolaryngology – Head & Neck Surgery at Stanford University School of Medicine. He received fellowship training in both headache medicine and otoneurology (dizziness and vestibular disorders) at Stanford University School of Medicine.
He specializes in diagnosing, managing, and treating the many causes of headache, facial pain, and dizziness. To provide the highest level of care, he takes a detailed history, performs a specialized physical exam, and collaborates with colleagues across the Stanford Health Care system. Dr. Baron develops a comprehensive care plan customized for each patient. He specializes in non-medication options, nerve blocks and other advanced treatments, Botox® injections, and the latest headache medications and devices.
Dr. Baron has a particular interest in the management of idiopathic intracranial hypertension (IIH), which results from pressure around the brain and causes headaches and problems with vision. He has established a multidisciplinary group of Stanford Health Care doctors to improve and coordinate care for people with IIH. The group includes doctors from several departments, including neuro-ophthalmology, neurosurgery, interventional radiology, and bariatric surgery and medical weight loss. They work together to determine the most effective medical and procedural treatments.
Dr. Baron also has a strong interest in the evaluation of acute vestibular syndromes and the management of dizziness in the emergency room. He has published in Journal of the Neurological Sciences, Otolaryngologic Clinics of North America, and Translational Behavioral Medicine. He has also written several chapters for the Stanford Neurology Resident Handbook. He has presented his research at conferences throughout the United States, and he is heavily involved with quality improvement projects and educating resident physicians.
Dr. Baron is a member of the American Headache Society, American Academy of Neurology, Catholic Medical Association, and Alpha Omega Alpha Honor Medical Society. -
Donald Barr
Professor (Teaching) of Pediatrics (General Pediatrics), Emeritus
BioDonald Barr is a Professor of Pediatrics in the Stanford School of Medicine, and Professor by Courtesy in the Graduate School of Education. He teaches in the Undergraduate Program in Human Biology, where he helped to found Human Biology's curriculum in health policy. His research has studied the effect of the organizational structure of the U.S. medical care delivery system on the quality of primary care. He has also studied cultural and linguistic barriers to health care access for low-income patients, and factors associated with higher rates of attrition from pre-medical studies among minority students at Stanford and other universities. The fourth edition of his book, Introduction to U.S. Health Policy: The Organization, Financing, and Delivery of Health Care in America, was published in 2016. The third edition of his book, Health Disparities in the United States: Social Class, Race, Ethnicity and the Social Determinants of Health, was published in 2019. In June 2003 Dr. Barr was awarded the Lloyd W. Dinkelspiel Award for Distinctive Contribution to Undergraduate Education at Stanford University. In 2006 he received the Miriam Aaron Roland Prize, which recognizes Stanford faculty who engage and involve students in integrating academic scholarship with significant and meaningful volunteer service to society.
