Prof. Hargreaves joined the Faculty in 2013 following the completion of his doctorate in law at the University of Toronto, where his thesis considered the privacy and legal implications of new mapping technologies that record public space for commercial purposes. It was supported by a major grant from the Canadian Social Sciences and Humanities Research Council.  Prof. Hargreaves also holds a BCL from Oxford University, where his dissertation considered the interaction between proposed privacy standards in APEC and EU laws regulating the outward flow of personal data to non-European states.  He also holds a JD from Osgoode Hall Law School and a BA in politics & sociology from McGill University.

Prior to joining CUHK, Prof. Hargreaves taught at Osgoode Hall Law School, worked as a policy advisor to the Canadian Internet Policy & Public Interest Clinic, and practiced law for the Ontario Ministry of the Attorney General in the constitutional law & policy branch. His areas of research and teaching reflect this background, with a dual focus on information & privacy law and constitutional law & legal theory. He welcomes discussions with LLB or JD students who are interested in writing independent research papers on those topics; prospective PhD students should, however, follow the established application procedures rather than contacting him directly with a proposal.

Prof. Hargreaves was Director of the LLB & Assistant Dean for Undergraduate Studies from 2015-2019, and won the Faculty’s Teaching Excellence award in 2017. He is external reviewer for a number of academic journals, a judge for the Undergraduate Awards (law category), an examiner for the overseas PCLL Conversion Examination, and sits on the Board of Advisors of Teach for Hong Kong.
