INSTITUTION AND LOCATION DEGREE Completion (if Date applicable) MMNYYY Illinois State University, Normal IL University of Minnesota, Minneapolis, MN B.S. 05/1988 Ph .D. 09/1993 Johns Hopkins University School of Medicine, Baltimore MD Post-doc 12/1996 FIELD OF STUDY Chemistry Biochemistry, Molecular Biology, & Biophysics Biochemistry & Cell Biology A. Personal Statement I have a strong background in the investigation of the biochemistry and biophysics of cytoskeletal motors. I have developed and utilized advanced biophysical & biochemical techniques (ensemble and single-molecule). I was the first to characterize the detailed ATPase kinetic mechanism of an "unconventional" myosin motor, and my laboratory has been a leader in the characterization of the force-dependent kinetics of muscle and non- muscle myosins. Much of our recent focus has been on the use of single-molecule and structural methods to investigate myosin-I motors, where we described the biophysics of membrane binding and the relationship between their mechanical and biochemical activities. Our recent work resulted in the determination of the structural mechanism of myosin force-...
