Using the tools of physics, chemistry, engineering, physiology and molecular biology, researchers are exploring the unfathomable complexity that affects our development and growth and individual responses to disease, drugs, and aging. John Wikswo, Gordon A. Cain University Professor of biomedical engineering and A.B. Learned Professor of Living State Physics  and University Professor of Biomedical Engineering, Molecular Physiology and Biophysics and Physics and Astronomy, gave this presentation at TedX Nashville on April 6, 2013.
