The QUASAR Group continuous to grow with Dr Bifeng Lei joining the Group as Research Associate to work on the development and optimization of ultra-compact high gradient accelerators, including ultra-compact dielectric laser accelerators and novel carbon nanotube (CNT)-based structures. In close collaboration with partners around the world, his mission is to drive the scientific progress in ultra-compact particle accelerators.

Bifeng studied Mathematics (B.Sc.) at Beihang University (BUAA), China and Computer Science (M.Sc.) for Large-scale Particle Accelerators at the University of Chinese Academy of Sciences (UCAS). He then worked as a scientific researcher at PITZ/DESY and Technische Universität Darmstadt (TUD), Germany, contributing to beam-driven plasma wakefield acceleration. Since 2013, he started his Ph.D. research in high-intensity laser-plasma physics and its applications in particle acceleration and radiation generation at the Friedrich Schiller University (FSU) in Jena, Germany.

After receiving his PhD, Bifeng joined the Helmholtz Institute in Jena as a postdoctoral researcher. His research mainly focused on laser-plasma based electron and ion acceleration and radiation generation. He developed the new method for generating ultra-intense optical vortex beam or ultra-strong magnetic field and position acceleration. By proposing a new way of highly sufficient ion trapping in near-critical relativistically transparent (NCRT) plasma, his work has opened a new routine to push the energy limit of laser-driven ion acceleration. He has also contributed to the investigation of electron beam instability in laser plasma wakefield accelerators (LWFA), which will benefit the most demanding applications of LWFA.

From 2022 to 2023, Dr Bifeng Lei started working as a postdoctoral fellow at Peking University in Beijing, China. His research focused on laser-driven particle acceleration, surface high harmonic generation and quantum electrodynamics. He worked as Principal Investigator on the project of petawatt laser-driven compact radiation source.
