Martin Weber’s main research clusters are in International Social and Political Theory, in (International) Environmental Politics, and in PE/IPE. His work has focused on contributions that Critical Theory can make to developments in normative International Political Theory, and to the ‘social turn’ in IR theory in general. It is also concerned with limitations and lacunae in critical theoretic approaches, and how these may be addressed. These theoretical interests are complementary to the more empirically oriented other clusters, informs these, and are in turn informed by them (see articles in European Journal of International Relations, Review of International Studies, Alternatives, Globalizations, as well as in contributions to edited volumes). In Environmental Politics, and PE/IPE, his work has focused on the political analysis of global governance, and in particular on global health governance and global environmental governance. He has published book-chapters and articles in key journals on these issues (Review of International Political Economy, Global Environmental Politics, Global Governance), and is currently finishing on a monograph on ‘Critical Theory and Global Political Ecology’.
