Research

Our lab develops advanced optical imaging technology and novel miniaturized devices, and use these new tools to investigate problems in neuroscience and biomedicine. Our research topics include biophotonics, optical imaging, two-photon microscopy, implantable biomedical devices, MEMs/NEMs devices, metastructures, brain imaging and modulation, and neural circuits.

Multiphoton microscopy

Multiphoton microscopy is a powerful tool in brain research as it can monitor and modulate neural activity at cellular resolution over large field of view. We combine hardware innovations and computational algorithms to enable high-throughput calcium imaging and holographic optogenetics.

Computational imaging

Computational imaging is an emerging field that jointly optimizes the imaging hardware and object reconstruction algorithms to achieve desired imaging quality. Leveraging recent advance in rapid prototyping of 3D micro optics as well as machine learning, we develop new imaging devices with advanced properties and functions such as compact footprint, 3D imaging and high acquisition speed.
