The Ci3 team is dedicated to helping faculty develop cutting-edge interdisciplinary research and programming to improve sexual and reproductive health globally.


Founder and Director

Dr. Melissa Gilliam is Professor of Obstetrics & Gynecology and Pediatrics, Chief of the Section of Family Planning & Contraceptive Research, and Associate Dean for Diversity and Inclusion in the Biological Sciences Division, as well as Director of Ci3 at the University of Chicago. 

Dr. Gilliam’s research builds on her clinical experience as a pediatric and adolescent gynecologist, using qualitative and quantitative methods to understand and find innovative approaches to the issues that affect the health and well-being of young women. Her community-based research seeks to identify adolescent attitudes towards sexual activity, pregnancy and contraception.

Recognizing that the complex interplay of systems that affect sexual and reproductive health, Dr. Gilliam has long incorporated partners from many disciplines in her research. She created the Center for Interdisciplinary Inquiry and Innovation in Sexual and Reproductive Health (Ci3) at the University of Chicago to facilitate collaborative research and programming, and to leverage the university’s resources to make significant improvements in the sexual and reproductive health of vulnerable communities.
