My research focuses on single molecule measurements of biological systems. One outstanding question is: how do motor proteins transduce chemical energy into physical motion? Another is: how does the structure and dynamics of membrane proteins affect their functions? We specialize in developing and applying high precision measurements using optical traps and atomic force microscopes to answer these and other interesting questions.
