Yimei Zhu PhD

Yimei Zhu is a Senior Physicist and Group Leader at Brookhaven National Laboratory (BNL) and Adjunct Professor at Stony Brook University. He received his PhD from Nagoya University and worked as a Research Associate at the University of Virginia. He joined BNL as an Assistant Scientist in 1988, rising through the ranks to become a Tenured Senior Physicist in 2002. Zhu has published 700 peer-reviewed journal articles and delivered more than 300 invited talks at international conferences. He is elected a Fellow of APS, MSA, AAAS, MRS, and MAS.

Zhu's research interests focus on understanding nano-to-atomic scale phenomena of strongly correlated quantum materials and advanced electron microscopy. His main research goals are probing charge, orbital, spin, and lattice correlations and their degrees of freedom, structure-property relationships, as well as interfaces and defects at ultrahigh spatial, temporal, and energy resolution. To achieve the goals and stay at the forefront of the field, he and his team develop and implement electron-microscopy instrumentation and methodology.

Zhu's experience in instrumentation development includes laser-free ultrafast electron microscopy, various stages for advancing sample environment capabilities, simultaneous imaging of surface and bulk at atomic resolution, and MeV Ultrafast electron diffraction (UED) and microscopy (UEM) with accelerator technologies. His expertise in quantitative microscopy includes valance electron mapping using electron diffraction, aberration-corrected atomic imaging, energy-loss spectroscopy, electron holography, Lorentz microscopy, ultrafast electron microscopy, and cryogenic in-situ microscopy in superconductors, multiferroics, topological 2D magnets, and quantum and energy materials.
