I am a PhD candidate in the philosophy department at UC Berkeley and the Irving and Jean Stone Fellow at the Townsend Center for the Humanities. My research focuses on normative human practices like law, language, and games -- on questions like: 'how does the normativity of these practices relate to moral normativity?' and 'how does the normativity of these practices constrain reductive theories of them?'

In addition to teaching at Berkeley, for the last several years I have been a philosophy instructor at San Quentin State Prison through the Prison University Project.

Before coming to Berkeley, I did the MPhil at the University of Cambridge. My MPhil Dissertation was on the normativity of concepts, and my adviser was Tim Crane. Before that, I received my BA from Williams College.

Beware: I have a doppelganger - another Jeffrey Kaplan who is an academic, studies law and language, is native to New Jersey, and enjoys basketball. Of the many Jeffrey Kaplans, I am this one.
