Research Description

I joined the Department in 2002 as a research lab technician to provide technical support in the study of the relationship of certain diseases to muscle function. This includes performing small amplitude sinusoidal analysis on muscle preparations from Drosophila, mice, and humans to measure mechanical properties including myosin-actin cross-bridge kinetics. Most recently, I have focused on studying the effects of heart failure, osteoarthritis, cancer and aging on human skeletal muscle obtained from biopsies. My specialties include muscle tissue dissection, chemical solution preparation, performing muscle experiments, data analysis, and data management.
