I am doing research in the intersection of motivation psychology, psychological methods and relationship science. I primarily use intensive longitudinal methods like experience sampling or ecological momentary interventions to better understand the everyday processes in intimate relationships. I am also interested in the improvement of smartphone-based assessment and intervention methods. As a signatory of the Commitment to Research Transparency and Open Science I am committed to implement openness and transparency in every step of my own research, and to encourage it in my reviews, as well as in cooperation with colleagues and students.
