The website introduces our mission and research directions in quantitative methodology for psychological and learning sciences. It brings together our publications, public preprints, research software, people, and lab news in one place. Our Publications section distinguishes peer-reviewed publications from preprints while keeping manuscript versions linked within a single record for each study. Through News, we will share updates on research, conference presentations, software releases, and developments in the lab. We invite researchers, students, and prospective collaborators to explore our work and stay connected.
