CV

Fei obtained his B.Sc. and M.Sc. degrees in Mining Engineering from China University of Mining and Technology (CUMT), China. He received his Ph.D. in Geotechnical Engineering from TU Bergakademie Freiberg (TUBAF), Germany, in 2020, where he subsequently worked as a research assistant and postdoctoral researcher. In 2021, he joined Northeastern University (NEU), China, as an associate professor at the State Key Laboratory of Intelligent Deep Metal Mining and Equipment. Since 2025, he has been an Alexander von Humboldt Research Fellow, conducting research at Clausthal University of Technology and, since 2026, at the Technical University of Munich (TUM).

Research Interest

Fei’s research focuses on thermo-mechanical behavior and cracking mechanisms of crystalline rocks under extreme conditions, with particular emphasis on granite. By combining laboratory experiments with multi-scale numerical modeling, including continuum and discrete element methods, he investigates how heating, cooling, confining pressure, mineral phase transitions, and boundary conditions govern thermal damage and fracture evolution in rocks. His work aims to bridge fundamental rock damage processes and engineering applications in geothermal energy, underground thermal energy storage, thermal-assisted rock breaking and drilling, as well as fire-induced damage assessment of natural stone and other geomaterials.
