Hong Qin

Associate Professor

Dr. Hong Qin is a theoretical and computational physicist whose work spans fusion energy, plasma physics, accelerator physics, artificial intelligence and machine learning, and quantum computing.

He earned his BS and MS degrees from Peking University in Beijing, then earned his PhD in astrophysical sciences from Princeton University in 1998, where he specialized in plasma physics and fusion energy. Prior to joining UW-Madison, he spent more than two decades at Princeton University, including as a principal research physicist at the Princeton Plasma Physics Laboratory and a lecturer with the rank of professor.

He coauthored the textbook An Introduction to the Physics of Intense Charged Particle Beams in High Energy Accelerators. In recent years, his work has helped establish two new research areas in plasma physics: structure-preserving algorithms for plasma simulation and topological plasma physics. He has mentored more than thirty Ph.D. students and postdoctoral researchers.
