One of the fundamental issues for the field of strategy is to understand how managers develop and make use of firm’s capabilities to achieve greater performance. My work attempts to contribute to this field of research by investigating on one hand how managers exploit and transfer firm’s capabilities and on the other hand how managers explore firm’s capabilities by identifying new market opportunities. My research also considers how firms acquire capabilities that allow them to improve their performance relative to new criteria. With growing demands on firms to improve their social and environmental performance, this research is of increasing importance. My work clarifies the role that both intentional search and unintentional discovery play in the acquisition or development of these capabilities. There are three main themes in my research which explore a) the choice of where to source capabilities, b) mechanisms for the internal development of capabilities, and c) the consequences of capabilities on performance and firm strategy. My research uses innovative data from several sources and at multiple levels. My latest research has been published in journals such as Strategic Management Journal, Strategic Entrepreneurship Journal, Research Policy, IEEE Transactions on Engineering Management, Journal Product innovation Management and Academy of Management Annals.
