Reading the
Milky Way,
star by star.

I’m Zhuohan Li, an astrophysicist exploring our
Galaxy’s history through dynamics, chemistry, and AI.

SCROLL TO EXPLORE
THE QUESTIONSGALACTIC ARCHAEOLOGY

Every star holds
a piece of the past.

I bring together the motions and chemistry of stars to study how the Milky Way formed and evolved. Machine learning helps me read these records across large astronomical surveys.

My research directions

A Galaxy in motion.

Following stellar motions to understand how our Galaxy was shaped.

History written in starlight.

Reading the chemical records that connect stars to their origins.

Learning to read the stars.

Using machine learning to turn survey data into physical insight.

A JOURNEY · AUGUST 2025

I heard the voice
of the boy
we once were.

On friendship, long roads, and the things that remain in time.
