2025 Recipients: Dean’s Award for Excellence in Mentoring


The Graduate Division and the Office for Postdoctoral Scholars are pleased to honor the recipients of the 2025 Dean’s Awards for Excellence in Mentoring for Graduate Students and Postdoctoral Scholars. The grad students and postdocs below are being recognized for their outstanding work as mentors for their colleagues. Now in its sixth year, this award celebrates the contributions of trainees who have formally or informally taken on some of the responsibilities typically held by traditional mentors, supervisors, and sponsors during their training, particularly in the areas of research, career and professional development, or social and inspirational mentoring.

Congratulations to the awardees and honorable mentions; the six awardees receive a $600 award, and both awardees and honorable mentions received certificates in recognition of their notable contributions at an awards ceremony on January 30.
