Since 2004 I have been trained in experimental social and personality psychology in many labs: in Poland, in the United States, in the Netherlands, and in France. I was granted with a PhD degree in 2010 at SWPS University of Social Sciences and Humanities, Poland and wrote a doctoral dissertation entitled Impulsive and Reflective Mechanisms of Persistence in Goal-Oriented Behaviors. As a researcher and lecturer working for the Vrije Universiteit Amsterdam and the SWPS University of Social Sciences and Humanities I focused on mechanisms of self-regulation and self-control related to health and addictions. In general, I conduct research in order to understand relationships between self-regulatory processes and decision-making processes, studying behavior in healthy and psychopathological samples.

I have developed my expertise not only in research projects but also in applied projects. For example, I am a co-author of an innovative system of competence identification and supporting motivation in the unemployed sponsored by the European Social Fund. I designed a system responsible for initiating a change in behavior of the unemployed. In this project, I also built a system of procedures and tasks that helps personal coaches to initiate and develop motivation to work in the unemployed.

I have extensive expertise in teaching and applying in my research many research paradigms and designs. Thus, I can work with language and discourse measures, questionnaires, implicit measures, reaction times, evaluative conditioning, physiological measures, and eye tracking devices. I have considerable experience working with lab software (e.g., Inquisit, OpenSeasame, MATLAB) or surveys (Qualtrics, Surveymoney). I also have extensive experience with many statistical procedures, such as ANOVA, regression (incl. the Hayes’ PROCESS), mediation and moderation, structural equation modeling (SEM), confirmatory factor analysis (CFA), cluster analysis, ROC, longitudinal models, and Item Response Analysis (IRT). I am fluent in working with LIWC (language responses analysis), Mplus, LISREL, AMOS, Mplus, ITRPRO, jMetrik, JASP, Comprehensive Meta-Analysis, G*Power, and other software packages.
