Linxing Preston Jiang

👋 Hi

My name is Linxing (Preston) Jiang (姜麟星, jiāng línxīng). I’m a sixth- and final-year PhD student in Computer Science at the University of Washington. My advisor is Rajesh Rao. I received my BS and MS degree in computer science, both from the University of Washington. I’m from Harbin, China.

🧠 Research interest

My main research interest is computational neuroscience. I am currently working on (1) predictive coding theories for perception and decision making, and (2) large-scale neural data pretraining. My ultimate goal is to provide functional explanations for brain circuits through theories, and to leverage modern machine learning systems for large-data-driven validation of these theories.

news

Feb 05, 2026	I have passed my PhD candidacy exam with thesie proposal: Foundation Models in Neuroscience: Do They Have a Scaling Future?
Dec 09, 2024	I finished my Research Scientist internship at Meta Reality Labs on neuromotor interfaces.
