Security Studies

International Relations Theory


Jan's research interests can broadly be divided into three main areas: security studies; international relations theory; and area studies with emphasis on Central Europe. In security studies his research focuses on theories of security, the relationship between politics and security, nuclear weapons and emerging security threats. Jan's work in international relations theory concentrates on the problem of theorizing trust at the international level. He has developed the concept of trusting relationship and currently works on anchoring the concept in a more general theory of international politics. Finally, he has had a long-standing research interest in area studies. This research has led to several articles on regional politics of Central Europe.
