Curriculum Vitae

Yoon Soo Park is the Ilene B. Harris Endowed Professor and Head of the Department of Medical Education. He holds a Ph.D. in Measurement, Evaluation, and Statistics from Columbia University. Park’s experiences include both academic and industry settings, with research interests and experiences across multiple disciplines in psychometrics, biostatistics, educational psychology, and medicine.

Park’s research agendas have focused on psychometric methods, focusing on statistical modeling of educational and psychological processes using latent class models and item response theory models. He has also actively engaged in interdisciplinary research in the social sciences, collaborating with diverse researchers and practitioners across disciplines. His work in the health professions education has advanced the preparation of learners in clinical reasoning and measurement of competencies through validity studies. His psychometric research has contributed to methods that reduce statistical error for complex data structures.

Park is the recipient of the Alicia Cascallar Award from the National Council on Measurement in Education (NCME). Park’s paper also received the Research in Medical Education (RIME) Best Paper Award by the Association of American Medical Colleges (AAMC). He is also the recipient of the ETS Presidential Award. He serves on editorial boards of leading medical education, measurement, and statistics/applied mathematics journals.

Park serves and contributes to national and international professional organizations. He is active in international collaborations, in both research and teaching, by organizing and leading partnerships with researchers and institutions in North America, Europe, Middle East, and Asia. Park is a member of the elected AAMC RIME Program Committee. He is currently Vice President of the American Educational Research Association (AERA), serving Division I: Education in the Professions.
