Xu develops STORM and related single-molecule-localization super-resolution imaging methods, along with new fluorogenic and multiplexed labeling strategies, to visualize cellular ultrastructure at ~10-20 nm resolution. The group is actively recruiting postdocs.

Zhang's lab develops two core optical technologies: spectroscopic single-molecule localization microscopy (sSMLM), which multiplexes emission-spectrum measurement with single-molecule localization to reach ~5 nm spatial resolution, and visible-light optical coherence tomography (vis-OCT), which exploits higher tissue contrast at visible wavelengths for micron-scale retinal and tumor-vasculature imaging in patients. Applications span cancer nanopathology and ophthalmology, including in-vivo human retinal oximetry.

Zhuang invented STORM super-resolution microscopy and MERFISH multiplexed spatial transcriptomics, and her lab continues to push single-molecule and multiplexed imaging techniques (e.g. a recent whole-olfactory-system map) to resolve cellular structures and RNA populations at nanometer-to-single-molecule resolution, well beyond the diffraction limit.
