Felix Thoemmes

Felix Thoemmes is an Assistant Professor in the Department of Human Development at Cornell University, within the College of Human Ecology. His work focuses on advancing statistical methods for causal inference, mediation analysis, and longitudinal research design. He specializes in addressing methodological challenges in psychological and educational research, particularly regarding nonexperimental data and missing data problems. His research integrates advanced statistical techniques with substantive questions in developmental psychology, mental health, and education policy.

Thoemmes' research interests include causal modeling, sensitivity analysis for unobserved confounding, and the application of structural equation modeling. He has contributed to understanding mechanisms linking socioeconomic status to child development, mental health trajectories in college students, and the effects of educational policies. His recent work emphasizes methodological rigor in addressing biases and improving reproducibility in psychological science.

He is particularly known for advancing methodologies in mediation analysis, regression discontinuity designs, and inverse probability weighting. His work bridges theoretical causal frameworks with practical applications, providing researchers with tools to better understand complex human developmental processes. Thoemmes has collaborated on studies involving chronic pain management, fire department wellness programs, and the impact of military training on personality development.

Thoemmes teaches courses on advanced statistical methods and has contributed to open-source software implementations of causal inference techniques. His research has been published in top journals across psychology, statistics, and education, demonstrating both methodological innovation and substantive scientific impact.
