Philosophy of Care
As a pathologist and an internist, I know the importance of pathology in the daily care of patients. I appreciate the importance of careful and well-thought out diagnostic pathology reports. I practice with this thought process, and teach my approach to trainees during my daily work.
Clinical Interests
Dr. Dwyre has clinical responsibilities in hematopathology, including leukemia, lymphoma and flow cytometry, as well as apheresis (the withdrawal of blood from a donor's body, removal of one or more components, and transfusion of the remaining blood back into the donor), which includes pediatric apheresis and progenitor-cell collection. He is involved in hematology-related clinical research involving leukemia, lymphoma and apheresis.
Research/Academic Interests
Dr. Dwyre's clinical research involves leukemia, lymphoma, and apheresis; hematopathology — leukemia, lymphoma, flow cytometry; apheresis — pediatric apheresis and progenitor cell collection.
