Research Interests

  • Dr. Dang's primary research effort emphasizes the development of novel treatment strategies for patients with lymphoma/CLL through the identification of new targets and the utilization of novel targeted therapies. To achieve this aim, he has conducted multiple clinical trials and is active in laboratory research with the goal of translating laboratory findings to the clinical setting for the ultimate benefit of the patient.
