Portrait of Dita Gratzinger

Dita Gratzinger, MD, PhD

Professor of Pathology
Director, Hematopathology

Dr. Dita Gratzinger is a hematopathologist who is dedicated to excellent patient care, to educating the hematopathologists of tomorrow, and to improving both by harnessing strengths across institutional and disciplinary lines. Dr. Gratzinger studies the architecture of supporting cells in the microenvironment as well as diagnosis of lymphoma on small volume specimens, and has a special interest in the role of patient-specific factors in manifestation of hematolymphoid disease, including immunodeficiency and dysregulation-related lymphoid proliferations. She is the founding chair of a multi-institutional consortium, the Cyto-Heme Interinstitutional Collaborative, which brings together hematopathologists, cytopathologists, and oncologists to optimize the benefits of small volume biopsy to lymphoma patients. She also heads the Stanford hematopathology service. Dr. Gratzinger received her B.A. from the University of California at Berkeley, her M.D. and PhD from Yale University, and completed her anatomic pathology residency, surgical pathology fellowship, and hematopathology fellowship at Stanford University.

Jean Oak, MD, PhD

Clinical Assistant Professor of Pathology (Hematopathology)
Director, Hematopathology Fellowship Program

Dr. Oak received her MD and PhD from University of California, Irvine, and completed her anatomic pathology and clinical pathology residency, hematopathology fellowship, and transfusion medicine fellowship at Stanford University. Her research and clinical interests include clinical assay development for tumor immunophenotyping, lymphocyte subset monitoring, and immunotherapy target antigen assessment in a variety of hematologic and immunologic disorders. As director of a clinical flow cytometry laboratory, she oversees the design, validation, and implementation of various immunophenotyping assays in addition to ensuring quality assurance and regulatory compliance for CLIA certification.

Associate Program Director, Pathology Residency Training (AP)

Oscar is an academic hematopathologist who completed anatomic and clinical pathology residency and hematopathology fellowship at Stanford in 2020. Prior to Stanford, he received his MD and PhD from UCLA. His interests include immunology, the pathogenesis and diagnosis of lymphomas, and global health.

Portrait of Brent Tan

Brent Tan, MD, PhD

Clinical Associate Professor of Pathology, Clinical Hematology
Assistant Director, Clinical Hematology
Associate Director of Quality for Informatics

My primary area of expertise is in the diagnosis of lymphoid and myeloid neoplasms. I am interested in the use of modern molecular techniques as a diagnostic aid as well as in providing prognostic information. My current areas of research focus on these areas.

Portrait of Albert Tsai

Albert Tsai, MD, PhD

Assistant Professor of Pathology (Hematopathology)

Dr. Tsai received his undergraduate training at the University of California, Los Angeles (B.S., Biochemistry, summa cum laude), followed by combined medical and graduate training at the University of Southern California (M.D., Ph.D., Biochemistry). He completed anatomic and clinical pathology (AP/CP) residency and hematopathology fellowship at Stanford University, receiving board certification in AP/CP and hematopathology. As an instructor, he performed clinical diagnostic duties on the hematopathology service while doing postdoctoral training in the laboratory of Dr. Sean Bendall, with funding from the Damon Runyon Cancer Research Foundation.

As a physician and hematopathologist, he seeks to mechanistically dissect myelodysplastic syndromes (MDS) using highly-multiplexed immunophenotyping — mass cytometry / cytometry by time-of-flight (CyTOF) and multiplexed ion beam imaging (MIBI). MDS is an especially complex and heterogeneous disease of abnormal blood cell development with increasing prevalence and few treatments. By combining practical experience clinically diagnosing MDS, next generation single cell proteomic approaches, fundamental discoveries in the biology of MDS, and knowledge of clinical laboratory testing, we hope to develop new clinical diagnostics for personalizing MDS therapies and therapeutic monitoring.

His clinical diagnostic duties are on the hematopathology service, primarily in the diagnosis of MDS, leukemias, lymphomas, and other hematopoietic diseases from blood, bone marrow, and tissue samples.

Portrait of Gerlinde Wernig

Gerlinde Wernig, MD

Assistant Professor of Pathology

Gerlinde is a pathologist by trade whose research centers around the mechanisms of fibrosis and new treatments. She enjoys staying active by hiking in the mountains and sprinting between clinic and lab. She finds optimizing complex lab protocols as gratifying as perfecting the recipes in her side-gig as an undercover chef.
