Dr. Wesemann is an Associate Professor of Medicine at Harvard Medical School and an Associate Physician at Brigham and Women’s Hospital. He is also a member of Harvard Medical School’s Program in Immunology and Digestive Diseases Center. He is the recipient of multiple awards, including Career Development Awards from the American Academy of Allergy, Asthma, and Immunology, and the Clinical Immunology Society. He is also a recipient of the 2014 New Investigator Award from Food Allergy Research and Education and the 2015 Young Investigator Award from the Interurban Clinical Club. He holds a Career Development Award in Medical Sciences from the Burroughs Wellcome Fund. Dr. Wesemann’s goal is to illuminate principles underlying lymphocyte antigen receptor diversity. Through methods in genetics, cell biology, and immunology, the Wesemann group is uncovering fundamental principles of somatic antibody evolution and discovering roles that symbiotic microbes play in shaping the recognition capacity of the adaptive immune system. In addition to advancing our understanding of host-microbe homeostasis, findings from this work are expected to have applications relevant to human health, including vaccinology, allergy, and autoimmunity.
