Dr. Robert Krause



Room KL 23/222c

Office hours

Consultation-hour by appointment.

I (he/him) am a postdoc in the Methods and Evaluation/Quality Assurance unit since the end of 2020. In my research I develop methods for analyzing social network structures and their selection and influence effects with individual variables (How are friendship structures built? How does our social environment influence our behavior?). Here I especially work with and on Stochastic Actor-Oriented Models (SAOM) and (Bayesian) Exponential Random Graph Models (ERGM). In this context I contribute to the further development of the RSiena R-package and I am a contributor to the Bergm R-package.

My teaching is also focused on methodology. At the FU I give courses in the Masters Education, Psychology, and Data Science.

My door is always open for questions about methods, social networks, scientific work and ethics, or D&D.

For inquiries about workshops (in English or German), simply send me an email.
