  • Immunotherapy and hematopoietic stem cell transplantation in patients with lymphoma

Alex Herrera, M.D., earned his undergraduate degree summa cum laude from Princeton University and received his medical degree from Harvard Medical School in Boston. While in Boston, Dr. Herrera completed his residency in internal medicine at the Brigham and Women’s Hospital, before pursuing a hematology-oncology fellowship at the Dana-Farber Cancer Institute/Massachusetts General Hospital.

Dr. Herrera's clinical and research interests center on immunotherapy and hematopoietic stem cell transplantation in patients with lymphoma. He leads several clinical trials evaluating immune checkpoint inhibitors and other novel agents for the treatment of relapsed or refractory non-Hodgkin lymphoma or classical Hodgkin lymphoma and in lymphoma patients undergoing hematopoietic stem cell transplantation. He also studies biomarkers of response and outcome in patients with lymphoma treated with immunotherapies or hematopoietic stem cell transplantation, including immunohistochemical and cytogenetic biomarkers and sequencing-based circulating tumor DNA detection, as well as gene expression, mutational profiling, and quantitative spatial immunofluorescence of tumor cells and the tumor microenvironment to identify biomarkers predictive of response to a treatment. The goal of these studies is to identify target populations for enrollment in rational prospective clinical trials using biomarker-based interventions to improve outcomes.

Dr. Herrera is the recipient of several honors, grants and awards, including the American Society of Blood and Marrow Transplantation/Biology of Blood and Marrow Transplantation George Santos Award for Best Clinical Science Article by a New Investigator, American Society of Clinical Oncology/Conquer Cancer Foundation Young Investigator Award, City of Hope K12 Paul Calabresi Career Development Award for Clinical Oncology, and the Lymphoma Research Foundation Larry and Denise Mason Clinical Investigator Career Development Award. He has published over 40 articles in peer-reviewed publications, abstracts and book chapters, and has been invited to present his work nationally and internationally.

Dr. Herrera is a member of the Toni Stephenson Lymphoma Center.
