  • Florette K. Gray Hazard

    Florette K. Gray Hazard

    Associate Professor of Pathology and of Pediatrics at the Stanford University Medical Center

    Current Research and Scholarly Interests My scholarly pursuits are primarily focused on the study of death and disease in the pediatric population. It is through this work that I am able to explore fundamental concepts of neoplasia, such as histogenesis and mutagenesis, while utilizing a variety of investigational techniques.

  • Michael Hendrickson

    Michael Hendrickson

    Professor of Pathology at the Stanford University Medical Center, Emeritus

    Current Research and Scholarly Interests Diagnosis of progressive stages of uterine cancer; classification of ovarian tumors; breast cancer diagnosis and prognostic factors, soft tissue neoplasm, uterine mesenchymal neoplasm.

  • John Higgins

    John Higgins

    Professor of Pathology at the Stanford University Medical Center

    Current Research and Scholarly Interests I work as a diagnostic surgical pathologist doing translational research in renal neoplasia and medical renal disease and neoplastic and medical liver disease. Subspecialty areas of clinical interest include diagnostic immunohistochemistry, renal, hepatic and transplant pathology.

  • Marie Hollenhorst, MD, PhD

    Marie Hollenhorst, MD, PhD

    Clinical Instructor, Pathology

    Bio Dr. Hollenhorst is a physician and scientist with expertise in non-malignant hematology, transfusion medicine, and chemical biology. Dr. Hollenhorst values the one-on-one relationships that she forms with her patients, and strives to deliver the highest quality of care for individuals with blood diseases. Her experience caring for patients drives her to ask scientific questions in the laboratory, where she aims to bring a chemical approach to the study of non-malignant blood disease.

    Dr. Hollenhorst pursued combined MD and PhD training at Harvard University, where she received a PhD in Chemical Biology under the mentorship of Professor Christopher T Walsh. She subsequently completed a residency in Internal Medicine at Brigham and Women's Hospital, a fellowship in Transfusion Medicine at Harvard Medical School, and a fellowship in Hematology at Stanford.

    Dr. Hollenhorst has a particular interest in the biology of platelets, which are cellular fragments that help the blood to maintain a healthy balance between excessive bleeding and excessive clotting. Working in the laboratory of Professor Carolyn Bertozzi of Stanford Chemistry, Dr. Hollenhorst is studying sugar-containing molecules that are found within platelets and are important in controlling their function and lifespan.

    Dr. Hollenhorst's research is supported by a Stanford Chemistry, Engineering & Medicine for Human Health Physician-Scientist Fellowship, a National Institutes of Health Individual Postdoctoral Fellowship, and a National Blood Foundation Early-Career Scientific Research Grant.

  • Michael Richard Howitt

    Michael Richard Howitt

    Assistant Professor of Pathology

    Current Research and Scholarly Interests Our lab is broadly interested in how intestinal microbes shape our immune system to promote both health and disease. Recently we discovered that a type of intestinal epithelial cell, called tuft cells, act as sentinels stationed along the lining of the gut. Tuft cells respond to microbes, including parasites, to initiate type 2 immunity, remodel the epithelium, and alter gut physiology. Surprisingly, these changes to the intestine rely on the same chemosensory pathway found in oral taste cells. Currently, we aim to 1) elucidate the role of specific tuft cell receptors in microbial detection. 2) To understand how protozoa and bacteria within the microbiota impact host immunity. 3) Discover how tuft cells modulate surrounding cells and tissue.
