Dr. Nathan also founded Einstein's Departmental Health Equity Task Force. The goal of this task force was to create a Departmental culture and workforce that understands the concepts of health disparities and structural racism, recognizes the ways in which society and the health system promote them, and works proactively to dismantle them.

In addition to her clinical and administrative duties, Dr Nathan is also active within ACOG, where she is a member of the Safe Motherhood Initiative Steering Committee. She was the Chair of the Maternal Sepsis Bundle workgroup and is a current member of the Health Equity Subcommittee. She also serves as a consultant to the New York City Department of Health, where she serves as the Co-Chair of the Maternal Mortality Review Committee. In this role, she reviews events leading to maternal mortality for the majority of cases occurring in New York City. These reviews form the basis for the development of recommendations for city and state level initiatives to combat the root causes of the high maternal mortality rates in New York City.
