Current Research Interests: Research interests concern the ability of the neuromuscular system to adapt to changing conditions. Current research projects include the development and testing of a surface-based EMG array electrode for monitoring motor unit activity, the identification of self-sustained firing activity in adaptations of motor unit discharge behavior to long-term exercise, central drive during maximal strength production, adaptations in motor unit discharge behavior during aging, motor unit synchronization, and the conjoint role of motor unit recruitment and firing rate in motor control.
