my research explores:
1) how various data-driven methods help us measure collective and idiosyncratic understandings or schemas of contemporary topics within race, sexuality, and migration discourse
2) how analytic methods and philosophical commitments (e.g., social epistemologies/ontologies) shape knowledge-building in psychology

representation of social others

this project combines insights from computational methods and memory & evaluation processes to study individual (cognitive) and collective (social) representations of others. specific focus on the flexible or rigid representation of categories (e.g., across time, learning, context, institutions, political projects, groupings), their origins, and how these representations may reflect and justify social oppression or motivate social change.

(inter)subjectivity & theory-making

important to this project is the development of statistical methods to quantify the idiosyncrasy or sharedness of judgments (e.g., “dangerous”, “racist”) across rater demographics (group membership), stimuli (faces, objects, social groups, and discourse), and political/conflict contexts as a way to map disagreements or shared understandings and steer them in anti-oppressive directions & to understand how these methods, in turn, inform psychological theorizing.

queer sexual health

this project focuses on identifying social barriers or facilitators to PrEP uptake (aka truvada, a daily pre-exposure prophylaxis pill for h.i.v. prevention). specific focus on mapping socio-moral judgments of men who take PrEP and how different socio-medical understandings of PrEP might promote or prevent collective regulation of sexual health .
