Sendil Ethiraj is the London Business School Term Chair Professor of Strategy and Entrepreneurship at London Business School. His research focuses on firms as complex systems. He received his Ph.D. at The Wharton School, University of Pennsylvania and was on the faculty at the Ross School of Business, University of Michigan for over a decade. Sendil Ethiraj’s research is built on the basic premise that firms are bundles of interdependent choices or complex systems. He unites his interest in understanding firms-as-complex-systems with the central questions in strategy that revolve around generating and sustaining competitive advantage. His research may be partitioned into two related themes. The first focuses on how complexity affects firm strategy and the unique tradeoffs that complexity imposes. The second examines firm capabilities and why they are complex and hard-to-imitate. His research has been published in the leading strategy journals including Administrative Science Quarterly, Management Science, Organization Science, and Strategic Management Journal. He served as Department Editor for the Organizations department of Management Science before joining the editorial team at Strategic Management Journal.
