Speakers
Dr. Gregory H. Nail, PhD, PE
Associate Professor in the Engineering Department at the University of Tennessee at MartinDr. Gregory H. Nail is a professor in the Engineering Department at the University of Tennessee at Martin where he teaches a variety of courses including fluid mechanics, hydraulics and hydrology, and hydraulic and hydrologic modeling. He holds a professional engineer’s license based on having passed both the Civil and Mechanical discipline-specific exams. Prior to coming to UT-Martin in 2002, he worked as a research hydraulic engineer for the United States Army Corp of Engineers for 11 years. He continues to be professionally active by working summer internships, carrying on consulting work, supervising senior design projects, and regularly delivering continuation programs, all oriented around computational hydraulic and computational hydrologic modeling. Dr. Nail earned his B.M.E. degree from Auburn University and his M.S. and Ph.D. degrees from Texas A&M University.
