The Computational Social Science Forum is an informal setting for the interdisciplinary exchange of ideas and scholarship at the intersection of social science and data science. We welcome social scientists with interests in data science methods and tools and data scientists with applications or interests in the social, behavioral, and health sciences. Our participants include graduate students, postdocs, staff, and faculty. Our goal is to improve computational social science research, support the development and research of our members, and foster new collaborations. At our weekly meetings, we engage in a variety of activities such as presentation of work in progress, discussion and critique of recent papers, introductions to new tools and methods, discussions around ethics, fairness, inequality, and responsible conduct of research, and professional development.
