HUMAN–COMPUTER INTERACTION

Understanding human decision-making

I am a postdoctoral researcher at Aalto University. I study how people allocate attention and make decisions when interacting with technology.

My research combines computational rationality, reinforcement learning, and human–computer interaction. I build models and simulations of human behavior to help researchers and designers understand users and improve interactive systems.

My doctoral research at the National University of Singapore was supervised by Shengdong Zhao and Antti Oulasvirta, with a focus on computationally rational modeling and heads-up computing.
