As of October 2015, Dr. Bal slowed clinical practice to devote time to corporate and legal work. Specifically, he is the President and CEO of Amedica Corporation, a manufacturer of medical-grade silicon nitride ceramics. Silicon nitride is one of the strongest ceramic materials, and Amedica is working on testing hip and knee bearing components that will improve patient lives. Also, Dr. Bal’s legal consulting has increased, with attendant demands on his time. Please email Dr. Bal anytime at email@example.com if you have questions. We will keep updating this announcement, so please check. Thank you for your confidence and support.
