About Millie
My research journey began in computational neuroscience and psychology, under Prof. Kiyohito Iigaya at Columbia’s Zuckerman Institute, where I explored how aesthetic emotions relate to psychiatric patterns. I later worked with Prof. Sam Gershman at Harvard as summer intern, studying reinforcement learning and anhedonia using multimodal health datasets.
To bring these insights into real-world systems, I joined the XR and BCI groups led by Prof. Steve Feiner and Prof. Paul Sajda, where I conducted multi-visit XR studies and contributed to the development of a large-scale physiological foundation model.
Currently, I’m a first-year PhD advised by with Prof. Xuhai “Orson” Xu on Human-AI-Interaction, Applied ML for Behavioral Health.
Looking ahead to the Ph.D. and beyond, my work aims to unify three research threads:
AI Agents for Self-Exploration and Introspection
Optimizing Behavioral Patterns through the Quantified Self
AI-assisted Creative Manifestation of Self
