In 2018, she founded, and now co-directs, the Global Belonging Collaborative, a large transdisciplinary team dedicated to developing the field of belonging through the dissemination of research, engagement in translational projects, and the pooling of international expertise. Among other things, the collaborative includes a publicly accessible belonging metric repository. Allen is a part of the research team contributing to Harvard Univerisity's Global Flourishing Study (GFS), focusing specifically on the theme of belonging within the broader framework of the 5-year longitudinal investigation across 22 countries and 240,000 participants.
