Between 2009-2019, Dr. Girnita was an Associate Professor, and then Professor of Surgery and Director of Transplant Immunology Division at University of Cincinnati. Since November 2019, he was recruited as a Professor of Pathology at Stanford School of Medicine. Dr. Girnita has authored over 40 scientific articles that have been cited over 1500 times. His research interest involves the alloimmune response in solid-organ transplantation, markers of antibody-mediated rejection, influence of various therapeutic protocols on desensitization and alloimmune response, structural matching and genetic polymorphism in transplantation.

  • Alex Gitlin

    Alex Gitlin

    Instructor, Pathology

    Bio Alex Gitlin, M.D., Ph.D. is currently an Instructor in the Department of Pathology at Stanford University School of Medicine. Prior to Stanford, Alex received his M.D. from Weill Cornell Medicine (2017) and his Ph.D. from Rockefeller University (2016) as part of the Medical Scientist Training Program (MSTP) at the Tri-Institutional M.D.-Ph.D. program. During his graduate training, Alex worked on the cellular and molecular mechanisms underlying germinal center reactions and the formation of long-lived humoral immunity. His work elucidated the mechanisms by which CD4+ T cells induce selective clonal expansion of germinal center B cells during the immune response. Currently, Alex's clinical and research interests lie in understanding the molecular mechanisms by which the innate immune system mounts inflammatory responses that are commensurate with the threat level posed to the host.

  • Matthew Gologorsky

    Matthew Gologorsky

    Research Assistant, Pathology Sponsored Projects

    Bio Matthew received his B.S. in Neuroscience from the University of Michigan in 2018. There, he worked in the lab of Dr. Paul Jenkins exploring the cellular and molecular mechanisms underlying neuropsychiatric disease. Matthew joined the Howitt lab at Stanford in the fall of 2018, where he is studying how intestinal tuft cells coordinate the activity of the gut epithelium, immune system, and enteric nervous system to mount effective defense mechanisms against intestinal parasites.

  • Dita Gratzinger

    Dita Gratzinger

    Associate Professor of Pathology at the Stanford University Medical Center

    Current Research and Scholarly Interests I have research interests in the interaction of hematolymphoid neoplasia with the microenvironment. For example, I use a combination of immunohistochemistry, immunofluorescence and image analysis techniques to evaluate the mesenchymal stromal cell compartment in myelodysplastic syndrome (pre-leukemic bone marrow failure disorder). I also have interests in lymphoma vasculature and the tropism of lymphoma for specific types of vasculature.

  • Dr Husein Hadeiba

    Dr Husein Hadeiba

    Affiliate, Pathology VA Faculty PTAs

    Bio My research interests center on understanding how dendritic cells (DCs) regulate the immune response. Specifically we are interested in the role of DC trafficking in inflammation and in the maintenance of immune homeostasis and tolerance. To understand these processes, we are examining the mechanisms of DC homing to sites of immune tolerance such as (i) the thymus-the site of central tolerance, and (ii) the gut mucosa-where immune responses to commensal and ingested antigens (Ags) are shut down. We are also interested in understanding how microenvironmental tissue factors influence DC development and their ability to imprint unique homing properties on T cells. DCs are unique messenger white blood cells of the mammalian immune system. They function as specialized antigen-presenting cells (APCs), whose main function is to process and transport Ags and microenvironmental signals from the tissues to the draining lymph nodes for presentation to T cells. In the last decade, a large number of DC subsets have been characterized in part defined by their expression of unique trafficking and adhesion receptors, and migratory properties. We therefore would like to understand how these trafficking and adhesion receptors define their function and phenotype and how they are regulated by the tissue microenvironment, with the hope of targeting unique DC subsets to suppress chronic inflammation or to improve anti-tumor responses in immunotherapy.

  • Felix J. Hartmann

    Felix J. Hartmann

    Postdoctoral Research Fellow, Pathology

    Bio Dr. Hartmann received a B.Sc. and M.Sc. in Molecular Biotechnology from the University of Heidelberg, Germany and his PhD from the University of Zurich, Switzerland for his research on T cell effector functions in human autoimmune diseases. Following his time in Zurich, Dr. Hartmann has joined Stanford University School of Medicine as a postdoctoral fellow. He is supported by fellowships from the Swiss National Science Foundation (SNF), the Novartis Foundation for biomedical research, and EMBO.

    Dr. Hartmann’s research focuses on combining single-cell and imaging proteomic technologies (mass cytometry and multiplexed ion beam imaging) with novel biological assays to reveal tumor-immune cell interactions that impact clinical outcome in human cancer. Most recently, he has developed a novel approach that enables analysis of cellular metabolism in individual cells and with spatial resolution in human tissues.

  • 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.

  • 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.
