Since October 1st, 2006, Sandra Kensen has worked at Sioo – Inter-university Center for Organizational Change and Learning in Utrecht, the Netherlands. Together with other lecturers and trainers, she develops learning programs for professionals related to organizing, intervention, and change. Before working at Sioo, she worked at Erasmus University Rotterdam (the Netherlands), Roskilde University (Denmark), and Tilburg University (the Netherlands). She has conducted research into topics of organizing, intervention and change. First as a theorist and observant, later as an interaction researcher (for instance, see Playing with Boundaries as Democratic Scholars, at: http://taos2.publishpath.com/manuscripts-taos-founders-board-members-associates which is published in: Administrative Theory and Praxis, 2003, no. 3, pp. 327-350). In the Sioo program Local Leadership, for instance, Sandra works with twenty Chief Executive Officers of Dutch local governments in order to search into possible ways of leading processes of change which connects different fields that make up one local society. At Sioo, theoretical deepening, systematic expansion in change methodologies, and pragmatic professional development are ever combined in playful, but relevant ways.
