// Physicist, builder, architect

Siyu Cheng's Home Page

I'm an about-to-graduate PhD student in Physics at Boston College.

I focus on one of today’s most fundamental challenges: applying AI-driven automation to real scientific research.
I design and build agentic systems for experimental quantum physics.
My PhD research specializes in probing rare-earth strongly correlated quantum materials using scanning tunneling microscopy (STM) and cryogenic UHV systems.
