BOSTON—Harvard Business School (HBS) announces a new cohort of Executive Fellows for the 2026 spring semester. The Executive Fellows program seeks to engage the expertise of outstanding practitioners—many of whom are alumni—to enhance teaching and learning at the School. Fellows partner with at least one HBS faculty member to bring their business experience to the HBS community.
Fellows contribute to the School by collaborating on both curricular and co-curricular activities. These include participating in course sessions in the MBA Program, providing career advice and mentoring to students, and assisting with short format offerings that provide opportunities for students to explore new topics. Fellows also collaborate with faculty in case development and other research projects. Fellow affiliations range from a few months to one year and may be extended.
“HBS launched the Executive Fellows program in 2020 to provide an avenue by which experienced business leaders and practitioners can contribute to the School’s mission in a variety of meaningful ways,” said Professor Len Schlesinger, chair of the program. “These remarkably insightful and generous Executive Fellows share valuable perspective from their own lived experiences, and these engagements have been enormously beneficial to our faculty and our students. We are grateful for the time and expertise they bring to our community.”
