He earned his Ph.D. in business administration from the Work and Organizations Department in the Carlson School of Management at the University of Minnesota. His research investigates the ways that different people self-regulate their responses to social contexts (e.g., supervisor influence, workgroup diversity, etc.) and ultimately harm and/or help others in the workplace. This has lead to work on the topics of positive and negative extra-role behaviors, unethical workplace behavior, social processes and emotions in the workplace, and workgroup diversity.
