i have shared my queer experiences as an illegalized immigrant:ย cnn, my undocumented life,ย daily princetonian,ย princeton alumni weekly,ย princeton summer journal

my research explores:

how data-driven methods help us measure collective and idiosyncratic understandings of contemporary topics within race, sexuality, and migration discourse 

how analytic methods and philosophical commitments (e.g., social epistemologies and ontologies) shape knowledge-building in psychology 

representation of social others

this project combines insights from computational methods and memory & evaluation processes to study individual and collective 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.

Mental representations of immigrants across documentation statuses and narratives 

Social structure learning and stereotype updating

(inter)subjectivity & theory-making

important to this project is the development of methods to better quantify disagreements or shared understandings of controversial issues across contexts and steer them in anti-oppressive directions & to understand how these methods, in turn, should inform psychological theorizing.

queer sexual health

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