Since 2003 she is professor of leadership and organizational change, University of Groningen. Currently she is director of the expertisecenter In the LEAD at the same university.

Expertise:
Janka Stoker her research focuses on themes like leadership, power, diversity and top management teams. Her current research projects are placed within the leadership center In the LEAD. This center offers a unique and novel approach by using insights from economics as well as from leadership and management scholars, to provide solid empirical evidence on the nexus between the individual leader and the organizational context. These projects generate insights on e.g. the functioning of boards in hybrid organizations, the effects of a crisis on leadership behavior, and cross-cultural differences in leadership behaviors.  

Ongoing projects:
Leadership in hybrid organisations (co-funded by Aedes)
In this post-doc project (in collaboration with Jacob Veenstra and Hary Garretsen), we investigate effective leadership in hybrid organisations, specifically in housing corporations. We study characteristics of boards and top management teams, in relation to effectiveness and firm performance.  

Top management dilemma’s: how accountability influences a focus on collective goals (funded by the Dutch Central Bank)
In this PhD-project (executed by Melanie de Waal, co-supervised by Floor Rink) we study the role of accountability in relation to both internal and external supervisors, and how both types of regulation influence a focus on collective goals. More specifically, this research examines in the field at the individual, team and organisational level 1) how the internal and external accountability audiences work, 3) under which circumstances they have an effect and, 3) how this relates to risk-taking at the organizational level.
