The James O. Armitage Center for Hematological Malignancies Research (JOACHMR) is comprised of interdisciplinary teams of renowned hematologists, oncologists, hematopathologists and basic science investigators, working together to diagnose and treat leukemias, lymphomas and multiple myelomas. They are actively involved in basic, translational and clinical research related to hematological malignancies.  The JOACHMR  has a large computerized clinical database, including pathology and genetic information on lymphoma cases as well as a large tissue bank of frozen lymphoma specimens and normal lymphoid tissues, which is an invaluable resource for the work of the Center.
