As a Postdoctoral Fellow and Data Scientist in the Human Diversity Lab at Princeton University, I'm interested in how people navigate the complex social world - including how we enact and are influenced by bias and inequity. In my research, I study mental representations of social categories and social networks, with an eye to how people's life experiences and sense of self inform their social cognitive processing. My work integrates experimental, survey-based, qualitative, and computational methods. I also take a meta-scientific approach, recognizing that the production of knowledge via science reflects the perspectives and interpretations of those doing the work. Proud graduate of the Mosaic and Social Cognition labs at Northwestern University.
