❝
Judith Su's background is in sensing, imaging, microfabrication and optical instrument building for biological and medical applications. Her research interests are in using imaging, sensing and rheological techniques to reveal basic biological functions at the molecular, cellular and tissue levels. Recently her work has centered on label_free single molecule detection using microtoroid optical resonators with a focus on basic research, and translational medicine through the development of miniature field portable devices as a tool to detect, understand, control and treat various diseases. She is also developing chemical sensors for environmental monitoring, reducing threats, assisting national defense and enabling clean sport competition.Show Less
