We use data to understand, evaluate, and improve the impacts of diversity on student thriving at Carnegie Mellon University.


Our Mission

As an applied research organization, the D3 Lab employs a dual approach to study how underrepresented or marginalized groups fare as students in terms of well-being, academic performance, and perceptions of support and belonging. Our first goal is to identify and understand the state of diverse experiences on the college campus, analyzing existing institutional data to identify areas for improvement. Using these insights, our second goal is to design and implement theory-driven interventions to improve student outcomes, to deploy these interventions as applied research projects, and to rigorously evaluate the efficacy of these interventions.



Our projects range from testing theoretical ideas in online experiments to multi-yearlong randomized control trials. The common thread is that this research uncovers valuable insights that lead to beneficial outcomes for students and university stakeholders.

The D3 Lab team is a unique combination of researchers and university leadership. Faculty members, graduate and undergraduate students from social psychology, behavioral economics, human-computer interaction, and organizational behavior make up an interdisciplinary research team. University administrators help bring these ideas to life within the Carnegie Mellon campus and beyond.
