I am a postdoctoral associate at NYU's Center for Social Media, AI, and Politics (CSMaP), working at the intersection of computational social science and political communication. I received my Ph.D. in Communication from UCLA. My research examines how individuals selectively engage with political information in algorithmically curated digital environments, and what these individual-level behaviors mean for broader outcomes such as audience fragmentation and distorted signals of public opinion.

With a focus on news selectivity, my work centers on three interrelated areas: (a) the measurement and conditions of news selectivity; (b) how different stages of digital news engagement shape the character of partisan alignment; and (c) how algorithmic curation and platform design shape information dynamics on digital platforms.

Methodologically, I combine large-scale digital trace data with computational text and network analysis to capture real-world behavior on platforms, alongside controlled experiments that isolate the causal mechanisms underlying engagement.

My broader goal is to advance empirically grounded understandings of how political participation and public debate are shaped on digital platforms, and to inform platform governance and design choices for more effective democratic communication.

I am also affiliated with the Political Communication & Behavior Lab (PCB)
