About DrDave

David W. Smith MD, ACP, BS (Chemistry), Board Certified (Internal Medicine Specialist), is recognized as a visiting scientist for both The Human Performance Laboratory for the Division of Sports Medicine at Cincinnati Children’s Hospital Medical Center and the North Shore Division of Neurosurgery and North Shore Neurological Institute, Chicago Illinois. Over his 30-year medical career, he served as Chief of Medicine at Reid Hospital & Healthcare Services and has founded commercial companies for developing his innovative product concepts: Xennovate Medical LLC, TBI Innovations LLC, and Delta Chase LLC.

As Chief Science Officer, he has served as lead design and medical education consultant to GlaxoSmithKline (GSK), a $90B+ Pharmaceutical and Healthcare company, Gentex Corp, the largest manufacturer of USAF helmets, and Materials Modification Inc., nano–materials and coating pioneer to the military complex.

 Dr. Smith has Intellectual Property and peer-reviewed publications in diverse fields of science, providing him with a unique perspective in overcoming a broad spectrum of significant medical paradigms.

His solid background in analytical chemistry (with an added emphasis in physics),  combined with his medical degree and internal medicine career, gave him insight into energy interactions and impartations to the human body, which has proven particularly useful in the study of Traumatic Brain Injury (TBI).
Dr. Smith pioneered “SLOSH Theory,” the basis of his Q-Collar invention designed to mitigate SLOSH energy absorption by the soft tissues of the human brain.  The Q-Collar has been proven to reduce the risk of brain damage from traumatic events and was the first product authorized by the FDA for this purpose. With Julian Bailes MD, a world-renowned neurosurgeon, he co-authored a presentation on “The Physics of Traumatic Brain Injury-Revisited,” delivered at the Congress of Neurological Surgeons Annual Meeting in September of 2016. At this event, the largest gathering of Neurosurgeons and Brain Injury Specialists worldwide, Dr. Smith presented his ideas on how the physics of a concussive wave (cavitation) can produce the chemistry of a TBI.
With Xennovate Medical, he presented several novel battlefield dressings to the Department of the Army Research Lab (DARPA) at the Aberdeen Proving Grounds and was the lead scientist in Xennovate’s two-year funding effort with DARPA’s Joint Improvised Explosive Device Defeat Organization (JEIDDO).  Dr. Smith consulted with Gentex Corp, who was successfully awarded a $90M contract in the field of mitigating the forces involved in human ejections from supersonic aircraft.
