Dalin (Darlene) Guo

Bio

I am a PhD student in Cognitive Science at UC San Diego, advised by Angela J. Yu.

I received B.S. in Electrical Engineering from Beijing Institute of Technology in 2016. I obtained my master degree in Intelligent Systems, Robotics, and Control from UC San Diego in 2018.

Research Interest

My research interest lies in machine learning and cognitive science. I use computational methods to understand reward-based human learning and decision-making under uncertainty. My current project is on multi-armed bandit task, where agents choose among novel options, trading-off between exploration and exploitation.
