Lab mission

Light often interacts with materials in complex, fascinating ways. Our research devises theories to model these interactions, build imaging architectures to sense them, and finally developing a deeper understanding of the world around us based on these interactions. We bring together ideas in signal and image processing, computational imaging, vision, machine learning, and compressive sensing to achieve this.
