Welcome to Nanoscience & Biotechnology Lab

About the Lab

The research goal of our lab is to develop a multidisciplinary program that advances nanobiotechnologies through three main research themes in advanced manufacturing, nanophotonics, and biomolecular sensing. The educational goal is to train students at different levels with fundamental engineering and physical concepts, provide them with opportunities to tackle complex real-world problems, and prepare them with the skills and mindset that allow them to strive in the ever-changing technology landscape.
