My recent research interests include theoretical investigation of high-brightness electron beam transport and calculation of beam wakefield/impedance in accelerator components. The relevant issues involve the collective beam instabilities, mechanisms of coherent radiation, and space charge effects in low- or medium-energy electron beams. My research work tends to develop analytical or semi-analytical theories based on physical models and benchmark with numerical approaches such as particle tracking simulation, particle in cell simulation or other advanced methods.

My current interest topics include, while not limited to, collective beam dynamics of high-brightness (high peak current, low energy spread and/or low emittance) electron beam in linear accelerators, modern recirculating accelerators, ERLs and diffraction-limited storage rings. Specific systems, such as femtosecond ultrafast electron diffraction/microscope (UED/M), or free-electron laser (FEL) systems are also under active investigation.
