​​I am the Jane Kim and Jung Min Lecturer in Undergraduate Teaching at Stanford University. I recently completed my PhD under the supervision of Michael Bratman (chair), Jorah Dannenberg, and Barry Maguire.

My dissertation is on cooperation, social practices of holding one another responsible (praise and blame; rewards and punishments; ostracism and esteem), and the relationship between the two. I am currently interested in the relationship between responsibility and economic ideology, and how our responsibility practices can be wielded to transform social norms and expectations, or reinforce the status quo, as the case may be. I am also interested in philosophical methodology in these and other areas. 

AoS: Ethics (esp. responsibility); Social Philosophy (esp. shared agency) 

AoC: Action Theory; Normativity; Moral Psychology
