Tim served 7 years in the U.S. Army as an airborne infantryman and later as an avionics maintenance technician. In 2017, Tim graduated from Tennessee State University with a bachelor’s of science in computer science prior to entering the Ph.D. program at Vanderbilt University. His focus at Vanderbilt is on extending the current state-of-the-art in health management technologies for cyber-physical systems to include system-level prognostics, predictive maintenance, and decision making.

In 2019 he started his company, Intelligent Systems, and has been working with National Facility Solutions to develop their flagship product, Facility Coach, which gives Facility Managers the predictive edge when it comes to maintenance and indoor air quality. In 2020 he was awarded a prestigious NASA Fellowship to support his thesis research and is working towards embedding the technology behind Facility Coach into iPerformance (National Facility Solutions product), so that he can focus on finishing his degree.
