Lehmberg’s research interests primarily lie at the intersection of strategic management and international business, and in particular, Japanese business. Bilingual in Japanese and English, Lehmberg bridges language and cultural barriers to provide opportunities for English speakers to better understand the Japanese context and business. His research examines strategic management issues including diversification, investment under uncertainty, innovation, and crisis in the Japanese business context, frequently using data only available in Japanese.
Extending his interest of management in crisis situations, Lehmberg is currently working with his NDSU colleague, Chanchai Tangpong, on research examining corporate turnaround. In the future, Lehmberg plans to extend this stream of research to examine similarities and differences in drivers of turnaround success in firms outside of the United States.
