Dr. van Ryn’s research focused primarily on the way “invisible actors,” such as implicit (unconscious) biases, inter-group anxiety, and stereotype threat affect social interaction processes and decision-making. Dr. van Ryn is the Principal Investigator in an ongoing, NIH R01-funded, national study of changes in attitudes that affect disparities in care, including unconscious biases, experienced by medical trainees over the course of their medical school and residency. In addition, she is the scientific director of a healthcare system-wide Diversity Climate Assessment with over 30,000 participants. Her work has improved the national awareness of how providers contribute to disparities in patient care and has led to greater understanding of how improved healthcare encounters positively impact patient outcomes. She has provided evidence-driven training to dozens of organizations, has been invited to give over 75 presentations on her research, both nationally and abroad, and she has authored over 120 journal articles, abstracts, and other written publications. Dr. van Ryn has received several awards and honors for her work. She served as a standing grant reviewer for the National Institutes of Health Social Psychology and Individual Personality Study Section and has served as an ad hoc reviewer numerous times for a variety of initiatives at the National Institutes of Health.
