Research

My research interests are primarily in the area of single-molecule spectroscopy and high-resolution optical imaging. I am working on the development of correlated atomic force and single-molecule fluorescence imaging and the development of techniques to allow simultaneous single-molecule force-extension and fluorescence measurements. Other areas of active research include: single-molecule imaging of cellulase activity on cellulose and single-molecule studies of riboswitch conformational dynamics.
