Research interests

Current research focuses on the distribution of risk and security under international and transnational law. The work looks at various different areas of law — international security arrangements, international criminal law, environmental law, investment and trade law, transnational developmental and financial arrangements — in order to gauge their overall impact in combination on the experience of risk. Stephen retains a special interest in climate change and human rights, in legal theory, drawing in particular on critical theory, and in rule of law promotion, the contemporary form of law and development.
