Dr. Houston obtained his doctorate in biochemistry from the University of South Alabama College of Medicine. His graduate work focused on enzyme discovery, and subsequent research at University of Virginia and Saint Louis University focused on enzymatic mechanisms involved in cellular communication. Dr. Houston followed his academic career with several years of research and development in enzyme manufacturing. This lead to his discovery of DPP-IV in certain enzyme blends and the eventual invention of the first proteolytic enzyme product targeted for those with autism. Dr. Houston then formed his own companies, Houston Nutraceuticals, Inc. and Houston Enzymes, in order to continue further development of novel enzyme products. Dr. Houston spends much of his time educating the public about enzymes and speaks at no cost at autism conferences and support groups.
