About me

• I’m Chang Cheng (成畅), a 1st year Physics PhD student at Stanford.
• I’m drawn to problems in fundamental physics (to me mostly particle physics and cosmology) that connect theories to calculable, measurable quantities.

Through my PhD, I hope to deepen our understanding of nature while developing ways of working with AI that strengthen researchers (try Flashcards or see Flashcards/About) and the scientific community.

Previously, I completed a Physics MSc at Imperial College London, where I took classes in QFT, relativity, and the Standard Model and beyond. I wrote my dissertation under the supervision of Arkady Tseytlin on the type IIB string theory (arXiv:2512.10746 [hep-th]). I also did research on AI safety and reliability at Callosum the summer before coming to Stanford.

Before Imperial, I completed a BA in Math and CS at Colorado College. During the final year of my undergraduate degree, my interest in physics grew, which led me to spend the subsequent year self-studying the subject before coming to Imperial.

Here is my CV.
