Research

My research heavily focuses on computational imaging and sensing. My recent works explore:

• Advancing non-line-of-sight imaging techniques (TIP'22, TIP'25, ICASSP'25, ICME'25)

• mmWave radar (RF) imaging (TMC'26, TIFS'25, TIP'24, TMC'24, CE'24, CVPR'26)

• Applying computational imaging and sensing to other applications, e.g., biomedical sensing and human-centric perception (IEEE COMST'25, Nature Communications'25, ICLR'25, ICCV'25)
