Curriculum Fellows are both educators and trained research scientists. As a result, CFs take a scientific approach to curricular redesign and course improvement, observing and identifying challenges and then designing and implementing modifications. These modifications are then evaluated and refined as necessary. CFs work in a variety of scientific fields including cell and molecular biology, immunology, infectious diseases, cancer biology and online learning, and each requires Ph.D.-level content and research expertise in addition to pedagogical experience and expertise. The CFs work together as a community, sharing their novel strategies for curricular revisions to promote integration across graduate courses and bringing their insights from current educational scholarship into HMS classrooms. CFs also teach graduate, medical, and continuing education students and develop and support diverse paracurricular programming for the HMS community.
