He received his PhD in 2001 from the University of Southern Denmark, focusing on fast-internationalizing small and medium-sized firms. His research focuses especially on international entrepreneurship and born-global firms. In recent years, he has particularly focused on studying international entrepreneurs that can avoid domestic path dependence by establishing ventures that, from the beginning, develop routines for a multi-cultural workforce, coordinate resources across nations, and target customers in several geographic places simultaneously. Furthermore, he has published a number of articles about lean and global startups combining the lean startup and born-global theories.
