About this Program

Through a departmental core curriculum as well as research area-specific courses, laboratory rotations, qualifying examinations, mentored research, and professional development, all MMI PhD students are prepared to engage in cutting edge research and scholarship that advances knowledge. MMI PhD students hone their scholarship, research and professional skills, whether in the context of MCBID, where they address problems in microbial pathogenesis, immunology and disease transmission; in MMBD, where research issues related to malaria, mosquito and arboviral biology are stressed; or in R3IM, which conveys a broad background in immunology and infectious diseases research, with special emphasis on critical thinking, logic, ethics, and written and oral skills to help graduates become communicators of complex scientific concepts and agents of change in their workplaces and communities.
