Research

My research examines how trust emerges, stabilizes, and fails in socio-technical systems. I combine field experiments, behavioral models, and large-scale platform data to understand how reputation signals, social similarity, and institutional design shape trust decisions.

A model of trust in AI systems

I am developing a dynamic model of trust in AI-mediated interaction. The model formalizes how trust thresholds adjust in response to experience, perceived control, and safety infrastructure.

The goal is to connect sociological theory of trust with the design and evaluation of intelligent systems.
