Microscale sensing technologies that integrate microfluidics and photonics are well-suited for chemical detection and cytometry (e.g. characterization of single cells and microdroplets in flow). This project focuses on designing, fabricating, and testing state-of-the-art photonic light sources and microfluidic networks. Our goal is to develop systems that enable accurate, high-throughput, and dynamic measurement of materials in flow, which will, for example, improve the ability to specify composition and describe variability in manufacturing for biotechnological applications. We offer a collaborative environment that couples multidisciplinary scientific interactions with state-of-the-art nanofabrication capabilities and advanced measurement tools.
