My main area of research is entrepreneurial decision making. I see individual actions as a key to the success (or failure) of entrepreneurial activity. Thus, I view individuals’ decision making as one of the most important aspects of developing an understanding of entrepreneurship. My theory of entrepreneurship is built using mathematical models of decision making. Physics, engineering, economics, and areas in sociology and psychology make extensive use of such models, but rarely does entrepreneurship research. Through my research, I try to demonstrate how the strengths of a mathematical approach to theory development can offer a compelling argument for its use in organizational studies and, more specifically, entrepreneurship.
