Research Interests

Dr. Hartwell begins her BME faculty appointment in Fall 2021.

The Hartwell Immunoengineering Lab combines perspectives from biomolecular engineering, drug delivery, and immunology to develop antigen-specific immunotherapies and vaccines for applications in autoimmunity, cancer, and infectious disease. Our research focuses on the design and development of molecules that achieve targeted and controlled modulation of the immune system in an antigen-specific manner, directing the immune response towards tolerance (for therapeutic applications in autoimmunity) or immunogenicity (for therapeutic or vaccine applications in cancer and infectious disease). Our rational molecular design approach is motivated by knowledge of inherent transport and cellular mechanisms, with a particular focus on targeting the mucosal immune system. Tuning the physicochemical properties of our molecular platforms allows us to direct 1) antigen delivery, 2) cellular interactions, and 3) the resulting immune response.

The development of molecules capable of targeting the immune system in a specific manner will address a pressing need for safer and more effective disease interventions across multiple disease settings, ranging from autoimmune diseases like MS to infectious diseases like COVID-19. For example, many current therapy options for autoimmunity and cancer act in a nonspecific manner, which translates to reduced efficacy and heightened risk of adverse side effects for patients. Additional value of this work lies in using the molecules we design as investigative tools to provide mechanistic insight, both to further our understanding of the immune response and to guide future design of immunotherapies and vaccines.
