My research broadly spans the areas of signal processing, communications, control, and machine learning. In recent years, my work has focused on the development of algorithms and theories for structured signal recovery using convex and non-convex optimization techniques. These include compressed sensing, low rank matrix recovery, phase retrieval, and graphical models. I have also worked … Continued
My research interest lies in the study of a new class of materials, called “photonic crystals”, which are able to control the behaviors of light in much the same way semiconductor crystals influence the behavior of electrons. Such material system provides a new dimension in our ability to control the properties of light, and is … Continued

To date, Impinj has enabled connectivity for more than 25 billion retail, pharmaceutical, healthcare, food, automotive and other items. The technology … Continued
My two key research goals are: Explore and invent (a) new nanotechnologies that can fabricate nanostructures substantially smaller, better, and cheaper than current technology permits; and (b) innovative nanodevices/materials (electronic, optical, magnetic, biological and medical diagnostic) that combine cutting-edge nanotechnology with frontier knowledge from different disciplines and can offer unprecedentedly better performances and/or lower cost, … Continued
My research interests range from semiconductor optoelectronic devices to materials and physics, with current foci on nano-photonic materials and devices for chip-scale integrated optics.
I am interested in robotics, computational algebra and computational molecular biology.
My current research is driven by two major quests: First, finding methods to combat increasing heterogeneity (mismatch) and stochasticity (noise) as transistors scale down to a few nanometers. And second, exploiting these methods to develop novel computing paradigms that scale beyond the limits of the current paradigm (purely digital hardware and strictly deterministic programs). In … Continued
I lead the Duke Imaging and Spectroscopy Program, which develops smart “super cameras.”
My research is focused on the development of new material and device platforms for integrated nanophotonics. We have extensive experience in design, optimization, simulation, and fabrication of high-speed, low-power, and ultra-compact reconfigurable integrated photonic structures for optical sensing, optical communications, optical interconnection, and optical signal processing. Our group has pioneered several high-quality hybrid CMOS-compatible material … Continued
