David A. Johnson, PhD
Thank you for watching my videos. I'm a PhD chemist, biochemist and molecular biologist and I have been teaching graduate and medical students for 44 years at Quillen College of Medicine, East Tennessee State University, Johnson City, TN 37614.
Most videos are about biochemistry, but some are about life and faith.
"It was pride that changed angels into devils; it is humility that makes men as angels. Faith is to believe what you do not see; the reward of this faith is to see what you believe. Love is the beauty of the soul." Saint Augustine
