Ruishi Qi

Faculty Host: Tony Heinz

Affiliated with: Gintzon Lab, Office of the Vice Provost and Dean of Research and Department of Applied Physics, School of Humanities and Sciences

Ruishi Qi will earn his PhD in physics in May 2026 from the University of California, Berkeley, where his doctoral research focuses on strongly correlated electron-hole fluids in van der Waals heterostructures. Using advanced optical spectroscopy techniques, his work demonstrated the electrical creation and control of stable excitons, trions, and biexcitons in thermal equilibrium and explored collective quantum phases such as exciton condensates and crystals. At Stanford, Ruishi will continue investigating quantum many-body phenomena in low-dimensional systems, connecting insights from correlated electron and exciton physics to emergent behavior in next-generation quantum materials.
