Research

Our group works at the intersection between the optics/photonics and computing, including optical signal processing, computational imaging system, accelerated optical and integrated photonic platforms for computing. We also study a broad range of design problems in optics and photonics (from macro-scale lens to nano-scale on-chip devices), leveraging physics-informed generative models.
