Ms Nivedita S is a research fellow with the Centre for International Law (CIL), National University of Singapore (NUS). Expanding her focus from nuclear law and policy to broader energy governance issues, her research explores law and policy issues across the energy, nuclear, ocean, security and environmental sectors. This includes the conceptualisation of international energy law, exploring legal and policy frameworks that can promote energy justice and governance of floating nuclear power plants. Regionally, her focus is on the development of ASEAN energy norms including conceptualising 'ASEAN nuclear governance'. Her primary research interest lies in the intersection of different areas of international law.

Before joining CIL in 2016, she trained at the Office of Legal Affairs of the International Atomic Energy Agency (IAEA), where she assisted with legal analysis and interpretation of international legal instruments and texts in the areas of nuclear safety, security, safeguards and liability, as well as research into international and treaty law issues.
