Felix Thoemmes is an Associate Professor in the Department of Human Development in the College of Human Ecology. He has a joint appointment in the Department of Psychology, and is a member of the graduate field of Statistics. Before he came to Cornell, he was a Professor at the University of Tuebingen, Germany, in the Center for Educational Science and Psychology, and an Assistant Professor in the College of Education and Human Development at Texas A&M University.

Broadly speaking, I work on topics of quantitative methods and design for the social sciences. In particular, I am interested in causal inference, both model-based and design-based. 

I just finished a grant by the Institute of Education Sciences to develop a web-based interface for the analysis of regression-discontinuity designs. An R package has been released on CRAN, and a web-based GUI using the Shiny environment was released in 2018. https://rddapp.shinyapps.io/shinyrdd_beta/

I continue to publish in methodological and applied journals, including Multivariate Behavioral Research, Psychological Methods, or Structural Equation Modeling. 

Finally, I work on collaborative projects with applied colleagues that span different areas of developmental psychology.

I am the outgoing programming chair for the annual APA conference, Division 5. 

I am currently an Associate editor for Multivariate Behavioral Research, and have reviewed for a large number of academic journals.

I teach Quantitative Methods (QM) 1, 2, (and 3) on a regular basis. All courses are cross-listed in Human Development and Psychology, and are open to graduate students and advanced undergraduate students. QM1 is a course on the analysis of randomized studies (mostly ANOVA designs), QM2 focuses on the analysis of non-randomized studies (mostly regression), and QM3 covers a mix of more advanced statistical methods. I try to implement active learning components in all of my classes, and am the faculty lead for an active learning grant in the Psychology department.
