    BioDr. Grant Barber is a Clinical Assistant Professor at Stanford University. His clinical passion is in the care of patients suffering from inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. After completing his medical training at Harvard Medical School, he completed his training in gastroenterology as well as a Master's degree in clinical research at Stanford. He completed additional training in advanced IBD management at Stanford before joining faculty. His research is focused on male reproductive health in IBD, quality improvement in the provision of IBD care, and economic studies to identify strategies that provide excellent outcomes while being sustainable within the healthcare system. He is an expert in tailoring evidence-based therapies to need of individual people with IBD.

  • Maria Barna

    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.

  • Leandra A. Barnes, MD

    Leandra A. Barnes, MD

    Instructor, Dermatology

    BioDr. Barnes is a board-certified dermatologist who provides care at Stanford Health Care Dermatology Clinics in Redwood City and Emeryville. She is also an Instructor of Dermatology within the Department of Dermatology at Stanford School of Medicine.

    Dr. Barnes specializes in diagnosing and treating a broad range of skin conditions, including hidradenitis suppurativa, skin cancer, and conditions that disproportionally impact people of color. As Co-Director of the Stanford Medicine Hidradenitis Suppurativa Specialty Clinic, her clinical focus includes maximizing awareness of and care options for this condition. Dr. Barnes is also the Founding Director of the Stanford Medicine Skin of Color Program and Director of Advocacy, Equity, and Inclusion in the Department of Dermatology at Stanford Medicine.

    Dr. Barnes’ clinical research focuses on identifying the underlying mechanisms associated with the onset and progression of hidradenitis suppurativa. These efforts include research on access to care among different patient populations and studies identifying immune-mediated characteristics of the condition. She is also engaged in efforts to promote broader and more effective outreach initiatives to drive melanoma awareness among minority populations and young children.

    Dr. Barnes has published her work in numerous peer-reviewed journals, including the Journal of Investigative Dermatology, JAMA Dermatology, and the Journal of the American Academy of Dermatology. She has also been an invited guest speaker at national and international meetings, including those for the Society of Investigative Dermatology and the World Congress of Dermatology.

  • Richard Baron, MD

    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.
