I am a hematologic oncologist specializing in treatment of lymphomas.
My research interests involve clinical trials and translational studies in indolent and aggressive lymphomas, as well as health outcome research in hematologic malignancies using registry and administrative databases (SEER-Medicare, NCDB). I am particularly interested in evaluation of treatment interventions using secondary data, while overcoming the inherent bias of such analyses related to their retrospective nature and limited clinical validation.
