Global Faculty

The Global Faculty expand NYU Law's faculty by inviting leading law professors from around the world who teach regularly at NYU while retaining their affiliation with their home institutions.  They specialize in diverse fields of law, not just international law, and are renowned scholars in their countries and areas of interest. Their courses provide an extraordinary opportunity for NYU students to learn from and interact with these eminent scholars and to gain a new perspective on important legal issues. Along with our Global Fellows and Hauser Global Scholars, the Global Faculty represent the heart of the Hauser Global Law School Program and a key element in the intellectual life of the Law School.

NYU School of Law's relationship with many global faculty is continuing and intimate over several years, rather than single one-semester or one-year arrangements. The global faculty are thereby integrated fully into the fabric of the Law School, both its academic programs and the collateral activities that largely define the institution.

He sits on the advisory board of the International Journal of Comparative Law, is a member of the European University Institute's Research Council, and is a trustee of the Equal Rights Trust.

He completed his undergraduate studies (BA LLB Hons) at the National Law School (Bangalore) in 2004 as the 'Best All Round Graduating Student'. He then came to Oxford as a Rhodes Scholar and completed his postgraduate studies (BCL with distinction, MPhil with distinction, DPhil) at Exeter College.

His monograph entitled A Theory of Discrimination Law (OUP 2015 hbk, South Asia edition and Oxford Scholarship Online, 2016 pbk) has been reviewed very positively in leading journals, including in Law and Philosophy, where Sophia Moreau said "In this magnificent and wide-ranging book ... Khaitan attempts what very few others have tried." In Ethics, Deborah Hellman said that its 'ambitious scope and the careful argumentation it contains make it one of the best in the field’.  In his review in the Modern Law Review, Kasper Lippert-Rasmussen claimed that "Khaitan's account is sophisticated, extensive and among the best normative accounts of discrimination law available." Colm O'Cinneide's review in the Oxford Journal of Legal Studies says that "Khaitan’s quest shows up the inadequacies of previous attempts to track down this Holy Grail, and the path he has laid down will encourage others to follow in his footsteps." The book won the Woodward Medal (with a cash prize of 10,000 Australian dollars) in 2019 for making ‘a significant contribution to knowledge in a field of humanities and social sciences.’ A full list of reviews is available here.

Prof Khaitan was awarded the 2018 Letten Prize, a 2 Million Norwegian Kroner award given biennially to a young researcher under the age of 45 conducting excellent research of great social relevance. He is using a part of the award towards setting up the Indian Equality Law Programme, aimed at capacity-building for early-career scholars. In 2020, he was awarded the Excellence in Engagement award by the University of Melbourne. Prof Pratap Mehta said in the context of this award that “No discussion of the rights of minorities in India is now conceivable without engaging with his conceptual and legal arguments”. At Oxford, he received the Oxford Policy Engagement Fellowship Award in 2020 and a special mention by the O2RB Excellence in Impact Award in 2021. He helped draft the Indian Anti-Discrimination and Equality Bill 2017.
