Di Fang

Di Fang is an Assistant Professor of Mathematics at Duke University's Trinity College of Arts & Sciences, with a secondary affiliation to the Duke Quantum Center. He earned his Ph.D. from the University of Wisconsin-Madison in 2019 and previously held positions as a Morrey Visiting Assistant Professor at UC Berkeley and Simons Quantum Postdoctoral Fellow at the Simons Institute.

Research Focus: His mathematical expertise lies in numerical analysis of partial differential equations with current emphasis on:

• Quantum computing theory and algorithm development
• Classical and quantum approaches to quantum system simulation
• Hamiltonian simulation involving unbounded operators
• Time-dependent oscillatory dynamics and superconvergence phenomena
• Error analysis for quantum-classical molecular dynamics

Publication Trends: Recent works demonstrate strong focus on advancing quantum simulation techniques, particularly through improved error bounds for quantum algorithms, time-marching methods for differential equations, and applications to open quantum systems. Theoretical developments frequently appear in top mathematical physics journals.
