Ruixu Geng

Hi! I am currently a Postdoctoral Fellow at the WeLight Lab, The University of Hong Kong (HKU), advised by Prof. Yifan (Evan) Peng. Before joining HKU, I received my Ph.D. from the University of Science and Technology of China (USTC), advised by Prof. Yan Chen. I obtained my Master's and Bachelor's degrees from the University of Electronic Science and Technology of China (UESTC).

Research

My research is in physics-anchored multimodal computational imaging, particularly in complementing optics with modalities such as radio frequency (RF) and acoustic signals.

Non-line-of-sight (NLOS) imaging — seeing around corners by inverting faint, diffusely scattered light. TIP'22, TIP'25, ICASSP'25, ICME'25

mmWave radar imaging — high-resolution imaging where cameras cannot go: calibration, reconstruction, adversarial robustness. TMC'26, TIFS'26, TIFS'25, TIP'24, COMST'25

Human-centric and biomedical sensing — vital signs and activity buried in clutter, increasingly by fusing radio with vision. Nature Comm.'25, ICCV'25, CVPR'26, ICLR'25
