Alexander Ku

I am a PhD student at Princeton, working with Tom Griffiths and Jon Cohen, and a Research Scientist at Google DeepMind. My research focuses on the computational principles underlying cognitive flexibility and long-term efficiency in humans, with the goal of translating these insights into building continually adaptive AI systems.

Research Interests: Continual Learning, Meta-Learning, Cognitive Control, Automaticity
