Rachel Sumner

Associate Director & Senior Lecturer

Rachel arrived at Cornell as a Ph.D. student in the Department of Human Development, where her dissertation focused on the development of purpose in life and identity among college students and adults. Through subsequent roles in a nonprofit organization and the Bronfenbrenner Center for Translational Research, she worked with youth work practitioners to use data as a tool for understanding and informing programmatic decisions. In January 2017, Rachel participated in the second CDP session for graduate/professional students and postdocs; it was a watershed moment for her. She’s been grateful to continue her involvement with CDP since then, first as a co-facilitator and coach and now as associate director and senior lecturer. Supervising our research and assessment efforts, Rachel works to understand CDP’s transformative impact on individual participants and the campus community. She also collaborates on the development and delivery of meaningful learning opportunities, including tailored programs for faculty and student-facing staff, a 7-week course for MBA students, and undergraduate courses about purpose in life.

Shannon Carratura

Research Aide

As a research aide, Shannon supports CDP’s research and assessment efforts, helping the team understand the center’s impact on participants and the broader campus community. She joins CDP after graduating from Rutgers University’s Honors College with a B.S. in Psychology and Exercise Science, where she was a research assistant in the Regulation, Action, and Motivated Perception Lab. Through this role, her honors thesis explored the psychological mechanisms behind political polarization. Alongside that theoretical work, she interned with the Rutgers Center for Disability Sports, Health, and Wellness, contributing to change through hands-on advocacy work to implement accessibility and inclusion on campus. That combination of understanding the mechanisms behind growing division across difference and directly contributing to change is what drew her to CDP.
