Her current research interest mainly focuses on signal processing for optical interconnect and optical communication systems, including the generation and detection of high-order format optical signals and all-optical signal processing based on optical nonlinear effects. She has made original contributions to the realization of ultra-fast optical signal processing for multi-wavelength self-coherent detected signals, including optical phase conjugation based on four-wave mixing, all-optical wavelength multicasting based on cross-phase modulation, and optical carrier-recovery based on stimulated Brillouin scattering.
