Grace Lee completed her undergraduate education at the University of Canterbury (New Zealand), obtaining an LL.B (Hons I) and B.Com in Economics. She was admitted as a Barrister and Solicitor of the High Court of New Zealand in the following year, and worked in private practice for several years specialising in banking and finance. She subsequently read for an LL.M in international law at the University of Cambridge (Hons I), which was generously funded by the British Chevening scholarship, Cambridge Commonwealth Trust (CCT) and the New Zealand Law Foundation. During her professional career, Grace has also worked on a variety of government funded research projects. Her main research interests are international and comparative environmental law and the law of the sea. Grace is currently reading for her Ph.D at the University of Cambridge (with the support of funding received from the UK Commonwealth Scholarship Commission and the CCT). Her research dissertation seeks to determine the extent to which the precautionary principle remains relevant, and whether it is the correct lens through which to regulate threats in the specific environmental settings that are premised on it. Through critically examining the principles of precaution and prevention at international law, and how these principles actually manifest, explicitly or implicitly, in selected environmental treaty regimes, the thesis seeks to circumscribe the proper scope of application of the precautionary principle, and determine whether there are some distinct ways in which the principle operates therein.
