Professor Colarelli's research is concerned with the question of how evolutionary theory and evolutionary psychology in particular can influence the ways we think about, conduct research on, and manage behavior in organizations. While evolutionary theory is the foundation of the life sciences, it has made few inroads into organizational psychology and management. His writing and research involve integrating these perspectives. He also conducts basic research in evolutionary psychology.

Professor Colarelli's work in I/O psychology focuses on: (1) mismatch between our evolved human nature and modern organizations, (2) understanding the use and non-use modern human resource technologies within the context of our evolved psychological adaptations; and (3) adapting human resource technologies so that they are more compatible with our evolved psychology.
