As the Evelyn Stefansson Nef Director of the Erikson Institute, Jane G. Tillman, PhD, ABPP, works to develop existing and new programs to support psychoanalytic education, training, scholarship, research, interdisciplinary studies, and advocacy that contribute to knowledge about human development across the lifespan and the ways identity is shaped in various sociocultural and historical contexts. Developing Riggs’ institutional archives and specialty library to contribute to scholarly research is also a significant aspect of the Erikson Institute. Applying the clinical learning available at the Austen Riggs Center to larger social contexts and problems in order to contribute to our local community and beyond by improving access to mental health care, addressing issues of stigma, collaborative care, and suicide prevention are all aspects of the Erikson Institute.

As a psychotherapist and psychoanalyst, Dr. Tillman treats patients at the Center. And, as a researcher, she is interested in suicide prevention and post-vention.

Dr. Tillman presents her scholarship and research in international forums including seminars, lectures, conferences, and publications.

Prior to entering the field of psychology Dr. Tillman was a flight paramedic for UNC Air Care. She is also an Episcopal priest serving a local congregation. Dr. Tillman notes, “In my work at Riggs I am made mindful of the various traumatic situations that contribute to suffering and the psychological and spiritual questions that arise in relation to suffering and meaning making.”

Outside of Riggs Dr. Tillman serves on several editorial boards for professional journals. She volunteers to present to local organizations and churches on the topic of suicide, trauma, and other organizational issues, and has served as an organizational consultant to several psychoanalytic institutes as they sought to understand institutional challenges.
