The Vaughan group develops new tools for high resolution fluorescence microscopy and uses these tools, along with established ones, to understand the molecular-scale organization of biological systems. On the tool development side, they are synthesizing new fluorescent probes, creating new methods for tissue expansion and clearing, and developing assays to understand the organization of the genome. On the application side, they partner with biologists and pathologists to apply imaging tools to the study of mouse neuronal circuitry, immune cell development, and pathology. Group members use diverse skill sets in chemistry, biology, and optics to tackle these highly interdisciplinary problems.
