Haogang Cai is an Assistant Professor in the Department of Radiology with research focused on biomedical and nanoengineering. He aims to build new paradigms at the intersection of nanotechnology and biological applications, working on nanoengineered biomimetic cell interfaces and optical metasurfaces in nanophotonics. His research investigates cell mechanobiology and the molecular mechanisms that occur at the micro and nanometer scale, linking key cellular functions and molecular processes. By utilizing advanced top-down nanolithographic technology from the semiconductor industry, he creates nanoengineered 'bio-chips' through bottom-up approaches, strategically placing biomolecules to form molecular architectures that mimic cell surfaces and microenvironments. He also studies the geometric effects of transmembrane receptor clustering on critical cellular functions, including adhesion and immune response, providing theoretical guidance for clinical platforms in cell therapies and nanomedicine. Moreover, his work in meta-optics encompasses the development of flat optics composed of nanostructures that manipulate light-matter interactions, similar to those found in naturally occurring materials.
