She integrates her research with the clinical care of patients with these diseases. Fleischman's longstanding interest in blood cell development began during her PhD graduate studies at Stanford. After completing her MD and PhD at Stanford, in 2005 she moved to Oregon Health & Science University (OHSU) for her internal medicine residency and medical oncology fellowship. She joined the University of California, Irvine in July 2013 as an assistant professor to develop her independent laboratory group focusing on the pathogenesis of myeloproliferative neoplasm (MPN), a chronic leukemia. Her overarching research goal is to identify what drives disease initiation in MPN and to ultimately translate her scientific discoveries into therapeutic benefit for MPN patients.
