The central focus of my research is innovation, particularly technological innovation.  Innovation is an extremely complex process that varies across places, applications, and over time.  Understanding it well enough to support public policy development demands that researchers employ a variety of methods, devise creative conceptual frameworks, engage in continual debate, and maintain a healthy sense of humility.  I am currently working in the areas highlighted below as well as advising doctoral students in these and many other areas.

Governance

High-Skill Migration
