My thesis work involves investigating the molecular mechanism of muscle contraction. Specifically, myosin’s structural transitions responsible for force generation. The primary technique I use to probe myosin structural dynamics is electron paramagnetic resonance (EPR) spectroscopy. Consequently, I have developed an interest in the application of EPR spectroscopy for studying biological systems, and the design and development of new and improved EPR technologies in biophysics.
