Office Hours: MWF 10-12 noon in BME 5.202O or by appointment

Research Focus

Zhang Laboratory is developing integrated photonic microsystems, semiconductor chips and nanotechnologies for imaging, sensing and regulating cellular processes critical to healthcare, environmental and defense applications. Current research focuses on developing tools and methods to understand and regulate complex biological networks critical to development and disease, and developing nano-micro fabricated photonic sensors for biomaterials characterization, fast pre-cancer detection and diagnosis. Nano-Micro scale science, Information, and Biomedicine are integrative components of Zhang's research that are used with advanced engineering tools to facilitate biomedical studies and develop point-of-care diagnostics for global health initiatives.
