معرفی
Chong-Yu Ruan is a Professor in the Department of Physics & Astronomy at Michigan State University's College of Natural Science. His research focuses on developing ultrafast electron diffraction and imaging technologies for atomic-scale resolution studies of materials and molecular processes.
His research interests center on ultrafast electron diffraction, nanomaterial dynamics, and photoinduced phase transitions. Key areas include plasmonic effects in nanoparticles, charge density wave transitions, graphite-to-diamond transformation pathways, and hot electron dynamics in functional materials. His work bridges fundamental physics with applications in optoelectronics, nanoelectronics, and clean energy sciences.
Analysis of his recent publications reveals a strong emphasis on femtosecond electron microscopy for quantum materials research, with particular focus on charge density waves, symmetry breaking phenomena, and nonthermal phase transitions. His group has pioneered techniques for high-throughput femtosecond imaging with atomic-scale resolution.
Ruan's laboratory develops advanced instrumentation including environmental cells for solution-phase diffraction, high-brightness ultrafast diffraction cameras, and RF-compressed electron microscope platforms. His team collaborates with experts in laser physics, electron microscopy, and accelerator science to push the boundaries of time-resolved structural analysis.
