Background
Dr. Thomas Hafner is a technical consultant and mechanical engineer focused on the analysis of mechanical systems, products, and components involved in incidents, failures, or other technical issues. He has experience investigating matters involving vehicles, piping systems, plumbing, and heating, ventilation, and air-conditioning systems. He has also conducted analyses related to damaged mechanical equipment and systems, properties, and incidents resulting in personal injuries. Dr. Hafner is proficient in a variety of technologies including three-dimensional (3D) scanning, engineering analysis, prototyping, 3D printing, CAD platforms such as SOLIDWORKS, and programming platforms such as MATLAB.
Dr. Hafner earned a doctorate in Mechanical Engineering from Purdue University in 2023. While at Purdue University, Dr. Hafner had a research focus of energetic materials including solid propellants, explosives, and pyrotechnics. During his bachelor’s degree at the University of Nebraska-Lincoln, he conducted research focused on computational fluid dynamics as well as served as a teaching assistant for an undergraduate mechanical engineering class. He has authored or co-authored nine different journal or conference papers.
