My broad research interests include leadership, leader development, leading change, and organizational failures. However, my current focus for the past several years has been around LEADER DEVELOPMENT: How do leaders develop? How can we assist in the development of leaders? In the past, I've conducted longitudinal research around a multitude of potential leadership variables over time and explored a series of potential paths from tacit knowledge to transformational leadership theory. As part of my broader work to develop/refine a theory of leader development, I have recently focused my attention on specific developmental experiences that seem to facilitate the development of leaders. This is largely qualitative research. I'm also attempting to identify potential natural experiments within these stories that may control for some of the more fundamental variables in my theory.
