Research Interests

Professor Leonard’s research group works at the interface of systems biology and synthetic biology in order to probe and program the function of complex, multicellular systems to develop transformative biotechnologies and enable a new paradigm of design-driven medicine. Using the tools of synthetic biology, biomolecular engineering, computational systems biology, and gene therapy, they develop technologies including programmable cell-based “devices,” immune therapies for cancer and chronic disease, smart vaccines, biosensors for global health applications, and tools for advanced metabolic engineering. By bringing an engineering approach to the investigation, design, and construction of biological systems, the Leonard group is advancing the frontiers of design-driven medicine to address unmet medical needs and create safe, effective, and long-lasting treatment options that improve both quantity and quality of life.
