I’m an HR thought leader, author, teacher and entrepreneur. My book, "Agile Talent" (Harvard, 2016), and articles describe the freelance revolution, what it means and where it’s headed for both individual freelancers and organizations that employ and depend on them. My Ph.D. is in psychology. I have been a senior HR executive for two Fortune 100 companies, taken two startups public, and teach at universities in North America, Europe and Asia.
