Aishwarya Ravindran, M.D.

Dr. Aishwarya Ravindran is a Senior Associate Consultant in the Division of Hematopathology at Mayo Clinic, Rochester, Minnesota, where she completed her residency, research, and hematopathology fellowships after earning her medical degree from Stanley Medical College in India. Formerly an Assistant Professor at the University of Alabama at Birmingham, Dr. Ravindran couples a busy clinical practice with a dedicated research focus on the phenotypic and genotypic correlates of rare histiocytic and dendritic cell neoplasms. She has published numerous peer-reviewed scientific articles and was also a recipient of the Mayo Clinic Dr. Hobart K.B. Allebach Fellowship award and the American Society of Clinical Pathology-40 under forty honorees for outstanding contributions to the field of pathology. As an active member of the multidisciplinary Histio-Care Network, she aims to improve awareness about these rare diseases.

Karen L. Rech, M.D.

Dr. Rech is a Professor of Hematopathology and Medical Co-director of the Immunostains Laboratory at the Mayo Clinic in Rochester, MN, USA. She received her MD from the University of North Carolina-Chapel Hill, followed by residency and fellowship training at Mayo Clinic Graduate School of Medicine. Inspired by a busy clinical practice, her research interests focus on novel diagnostic markers in hematopathology. As a founding member of the multidisciplinary Mayo Clinic Histiocytosis Working Group, she has developed unique expertise in the pathologic diagnosis of histiocytic neoplasms. Her expertise is shared through her pathology consultation practice, educational seminars to pathologists worldwide, and seminal publications on the pathological features of Rosai-Dorfman disease, Erdheim-Chester disease and malignant histiocytic neoplasms. She currently serves on the Non-LCH Steering Committee for the Histiocyte Society.

Diana Morlote, M.D.

Diana Morlote earned her medical degree from the Herbert Wertheim College of Medicine before completing anatomic and clinical pathology residency at Mount Sinai Medical Center in Miami, Florida, in 2017. She joined the University of Alabama at Birmingham (UAB) Department of Pathology as a molecular genetic pathology fellow. Upon completion of one fellowship, Dr. Morlote began her second in hematopathology at UAB. In 2019, she joined the department as an assistant professor.

Dr. Morlote is board certified in Molecular Genetic Pathology and Hematopathology. Her research interests focus on the molecular characterization of hematologic neoplasms and their diagnostic and prognostic implications. She serves as Director of the Hematopathology Fellowship and leads the Hematopathology resident rotation. She is Chair of the Critical Values Committee and one of the module directors for the Hematology-Oncology Module at the Heersink School of Medicine at UAB. In addition, she serves as director of two UAB Outreach Service Labs in the McDonald Clinic and Urgent Care.

Liuyan (Jennifer) Jiang, M.D.

Dr. Liuyan (Jennifer) Jiang was born and raised in Shanghai, China. After she graduated from Shanghai First Medical University (current Fudan University Shanghai Medical College), Dr. Jiang pursued anatomic and clinical pathology residence training at University of Texas at Houston Medical school. Subsequently she completed surgical pathology fellowship at University of Texas MD Anderson Cancer Center, Houston, TX; then hematopathology fellowship at National Institutes of Health/ National Cancer Institute, Bethesda, MD.

Dr. Jiang joined Mayo Clinic Florida immediately after completion of fellowship in 2008. She served as a general pathologist at the beginning of the career; later she focused on the Hematopathology service. She had been the medical director of flow cytometry laboratory for approximately fifteen years; then promoted to the division director of Hematopathology at Mayo Clinic Florida since 2022. Dr. Jiang currently is a Professor of Laboratory Medicine and Pathology at Mayo Clinic School of Medicine and Science.

Dr. Jiang’s clinical practice and research encompasses three broad areas: developing biomarkers in B cell lymphomas and T cell lymphomas for pathogenesis and treatment options; conducting immunohistochemistry and/or flow cytometry analysis for certain antigens on neoplastic lymphocytes for treatment choice; and epidemiologic and biostatistical study on relationship in clinical phenotype, molecular genetic mutation, and treatment outcome in acute leukemia. Her recent research focuses on tumor micro-environment associated with lymphomas and plasma cell disorders, molecular genetic progression in myeloid neoplasm pre- and post-bone marrow transplant. With the expansion of clinical practice and research at MCF, Dr. Jiang recently developed keen interest in the diagnosis, pathogenesis, and new treatment in histiocytic disorders. She participated in the Histiocytic working group since 2023 and now is the active member of Histio-Care Netwrok.

Yanna Ding, M.D., Ph.D. 

Dr. Yanna Ding earned her medical degree from Xiangya School of Medicine and a master’s degree in pathology from Zhongshan School of Medicine, Sun Yat-Sen University in China. She then completed her Ph.D. in Pathology and Immunology at the University of Alabama at Birmingham (UAB). Dr. Ding completed residency training in anatomic and clinical pathology (AP/CP) at the Medical University of South Carolina in Charleston, SC, followed by a two-year fellowship in Hematopathology at the National Institutes of Health / National Cancer Institute in Bethesda, Maryland.

Dr. Ding recently joined the Department of Pathology at UAB as a consultant Hematopathologist from University of Washington where she served as an Assistant Professor and a Hematopathologist. Dr. Ding serves in editorial board or as reviewer for several medical/pathology journals and as a member of the Education Committee in International Clinical Cytometry Society (ICCS) and USCAP. Dr. Ding’s clinical and research interests include diagnosis and pathogenesis of lymphoma, leukemia, autoimmune/immunodeficiency disorders, VEXAS syndrome as well as MRD diagnosis by flow cytometry. Dr Ding recently developed interest in diagnosis, pathogenesis and treatment in histiocytic disorders.
