Research Interests:

- Overview - My research interests focus on the development of new molecular diagnostic tests and flow cytometric targets which can aid in the diagnosis, subclassification, determination of prognosis, and treatment monitoring in patients with hematopoietic neoplasms. In addition, I am interested in evaluation of the usefulness of newly identified mutations both as diagnostic targets as well as possible targets of directed therapies. I am also interested in the monitoring and significance of minimal residual disease in different hematopoietic disorders.

Clinical Focus:

My clinical focus is in the area of neoplastic and non-neoplastic hematopathology of adults and children with an emphasis on a multifaceted approach including morphology, immunohistochemistry, flow cytometric immunophenotyping, fluorescence in situ hybridization, cytogenetics, and molecular testing. This approach is used to diagnosis the full range of hematopoietic malignancies and to evaluate for residual or recurrent disease following treatment. As Director of Molecular Hematopathology, I additionally have a leading role in supervising the development and evaluation of new molecular hematopathology tests in order to maintain a state-of-the-art diagnostic hematopathology laboratory.
