His scholarship has also been selected for the Harvard/Stanford/Yale Junior Faculty Forum (twice) and for the New Voices in Civil Justice Workshop and has appeared or is forthcoming in such publications as the Columbia Law Review, Georgetown Law Journal, and Boston University Law Review, as well as in an edited collection of essays on private law theory published by Oxford University Press.
