Yeshim's work and research examine how people respond to violence, both in their everyday lives and in their group’s histories, and how belonging to certain social groups influence those responses. She has published in leading academic journals including European Journal of Social Psychology, Journal of Community and Applied Social Psychology, and International Perspectives in Psychology. While Yeshim has taught a range of courses across social and community psychology, she particularly enjoys teaching foundational courses and research methods. 

She has a PhD from the Psychology and Social Intervention Program in the Department of Applied Psychology at New York University and a B.A. in Psychology from Cornell University. Before joining Duke Kunshan, she was a Senior Research Scientist at Global TIES for Children, New York University.
