I am Gjalt-Jorn Peters, associate professor at the department of Theory, Methodology and Statistics at the Psychology faculty of the Open University. My career started in behavior change science, studying why people start using ecstasy, why they use it the way they do, and they they stop (https://doi.org/kxkg). After a postdoc (see http://fear-appeals.com) I switched to the Open University’s Methodology & Statistics department, and since then my focus has also shifted to more methodological work. In addition to happily STABbing at the OU, I’m involved in the ELSA-lab Poverty & Debt (ELSA stands for Ethical, Legal, and Societal Aspects of AI) and I coordinate the monitoring of the various interventions in Heerlen-Noord, one of the deprived neighborhoods that the Netherlands will invest in over the next 25 years (https://verlicht.one). I maintain a few (well, too many) R packages (https://opens.science), for example {rock}, the package implementing the Reproducible Open Coding Kit (the ROCK, a standard for open qualitative research, https://rock.science), the {preregr} package for creating preregistrations but also preregistration forms, the {behaviorchange} package to help develop and study behavior change interventions, the {metabefor} package to facilitate distributed, open, scalable, extendible systematic reviews (https://sysrevving.com and https://archeologists.opens.science), and the {psyverse} package implementing Decentralized Construct Definitions, a tool to create comprehensive and easily reusable or adaptable construct definitions (https://doi.org/jnjp).
