M. Antonia Biggs, PhD

Associate Director and Professor

M. Antonia Biggs, PhD, is an Associate Professor and social psychologist at ANSIRH. Dr. Biggs’ research is dedicated towards better understanding the challenges faced by people wanting to access sexual and reproductive health services. Dr. Biggs conducts research in the U.S. and Chile and uses both quantitative and qualitative methods to better understand people’s experiences accessing contraceptive and abortion care, contraceptive provision in primary care settings, the psychological well-being of women having abortions, and the effects of parental notification on minors’ access to abortion. Dr. Biggs is currently leading a study examining the psychosocial burden experienced by people accessing abortion care, as well as a national study assessing interest in alternative models of medication abortion provision, changes in prevalence of self-managed abortion, and people’s attitudes towards criminalizing self-managed abortion. Her work aims to inform clinical and public policies that will improve patient care and ensure patient autonomy and well-being. Dr. Biggs holds a B.A. in Psychology from the University of Wisconsin, Madison, and an M.A. and Ph.D. in Psychology from Boston University.
