My research focuses on engineering materials at the nanoscale, with particular efforts in excitonics, light emission, sensing, and devices. Read more at congrevelab.stanford.edu.
My group is generally interested in the quantum theory of light-matter interaction. We have carried out extensive works on waveguide quantum electrodynamics. In recent years we have also started theoretical works on the quantum theory of the interaction between free electrons and photonic structures.
Epitaxial growth of novel materials for quantum devices, Nanoscience and quantum technology, high efficiency solar cells and hydrogen generation, photonic biomedical sensors.
My work has focused on exploring the feasibility of building, and issues in using quantum computing. I chaired the National Academies study on quantum computing that was published in 2019.

My research focuses on new ways to work with light and to understand how it works. One current theme is programmable optics that perform entirely new kinds of operations. Such optical circuits, based on complex silicon photonics, can automatically set themselves up and solve many problems in sensing, communicating and processing classical and quantum information. This also links to a new fundamental "modal" view of optics that has led to proofs of new physical laws, including new ways to look at the quantum mechanics of light. DAB Group.
My current research is on new device structures and materials to improve solar cell efficiency and lower cost, continue scaling MOS transistors and semiconductor materials to nanometer regime, 3-dimensional ICs with multiple layers of heterogeneous devices, and optical interconnections.
My interest in quantum is focused on the quantum mechanics of modulated electrons and their applications to ultrafast electron diffraction, ultrafast electron microscopy, high temporal and spatial resolution probes of quantum states, and control of solid state qbits. My interests are both in the theory of these aspects of quantum science and also in the practical implementations of applications.
I work on quantum photonics and scalable quantum systems based on optically interfaced spins in semiconductors (diamond and silicon carbide).
My current quantum research interests include
- information theoretic properties of near-term quantum algorithms
- development and application of information theoretic tools for spin chemistry simulations and analysis
- quantum computing for classical compression
- quantum cognition
Computational Imaging Lab
Quantum-inspired computational single-photon imaging, e.g. for applications in non-line of sight imaging (project 1, project 2) or imaging through scattering media (project 3). We develop time-resolved single-photon-sensitive imaging systems that enable us to see around corners and through obscurants.
Deep optics: end-to-end optimization of optics and image processing (project 1, project 2, project 3). We use artificial intelligence methods to jointly design optical elements and image processing algorithms for next-generation cameras.
Artificial intelligence-driven holographic displays for VR/AR (project 1, project 2). We develop AI-driven holographic displays that enable new user experiences and optimize perceptual realism and visual comfort in virtual and augmented reality applications.
I work primarily in classical coding and information theory, and have interests in quantum error correcting codes and quantum information theory as well.
