Andrew Lakoff, a Ph.D. candidate in Anthropology, explores in his dissertation, Pharmaceutical Reason: Subject and Psychotrope in Buenos Aires, how cosmopolitan science constitutes contemporary norms of personhood, and how these norms, taken on as identities, function in a given social milieu. Lakoff’s fieldwork includes study, in both Paris and Buenos Aires, of a French genomics company engaged in collecting and analyzing DNA samples from mental patients in an Argentine mental hospital. His strategy is to follow a class of objects– in this case, psychopharmaceuticals, or molecules designed to transform behavior through action on the brain–as they assemble, across institutional and epistemological spaces, what might be called a neuroscientific subject. Andrew Lakoff has been named Marian E. Koshland Fellow for 1999-2000.
