Dr. Mutwiri's primary interest is research and development of vaccines and immunotherapeutic agents. His laboratory is currently focused on the discovery and development of novel vaccine adjuvants, and investigating their mechanisms of actions. They are also exploring various approaches to improve the efficacy of vaccines and immunotherapeutic agents through appropriate formulation and delivery. Another aspect of his current research activity is investigating how innate immune responses are regulated in the intestines, using TLR9 activation as a model.
