About the Speakers

Greg Sullenberger retired at the rank of Corporal after spending 20 years with the Pennsylvania State Police. Greg served as a Patrol Trooper, a Patrol Supervisor, a Training Instructor, the Collision Investigation and Training Coordinator, and as a full time Collision Analysis and Reconstruction Specialist.

Greg attained ACTAR accreditation in 1995 and has been qualified as an expert in many counties in the state of Pa., also in West Virginia and Maryland, and in federal court. He has also qualified as an expert in Occupant Kinematics.

Greg was deputized as a United States Marshall and worked on the forensic mapping team at the crash of United Airlines Flight 93 on Sept. 11, 2001. Greg and the other members of the team mapped all of the evidence and created a diagram for the FBI. The team was commended, by the FBI, for their work.

Greg is currently an adjunct instructor for the University of North Florida and teaches crash investigation courses internationally. Greg has been an invited guest speaker at several crash conferences around the United States and in Great Britain and Denmark.

Greg is a member of the Society of Automotive Engineers, the National Association of Professional Accident Reconstruction Specialists, President of the Pennsylvania Collision Analysis and Reconstruction Society, and the National Eagle Scout Association.

Greg was published by the SAE on the topic of Pedestrian Impact on Low Friction Surface. The SAE paper number is 2014-01-0470.

Occupant Kinematics (occupant positions)

Mr. Tennent has been designing, developing and working with tires for over 20 years. During the Ford/Firestone ATX recall he analyzed and
reported on over 300,000 tires!

He also managed Bridgestone Motorsports and Firestone Racing for several years where he was very poplar among the staff at the IRL, the drivers and team owners such as David Letterman, Chip Ganassi and Roger Penske.

Three years ago, Mr. Tennent retired from Bridgestone/Firestone as one of the engineering managers in charge of Motorcycle, Kart and Government Products (This included passenger, light truck and commercial products) for North America.


Tire Failures in Crash Investigation

He has the distinction of being the only treating physician in Louisiana that has been qualified to testify as an expert in motor vehicle crash biomechanics. He is one of only a handful of doctors to do this nationwide. In addition to his undergraduate and doctorate degrees, Dr. Barczyk has over 300 hours of post doctorate training in biomechanics, occupant kinematics, vehicle dynamics and is an ACTAR Certified Accident Reconatructionist(ACTAR#3183). He also has advanced training tradition Traffic Crash Reconstruction and vehicle dynamics. Dr. Barczyk is Certified by ACTAR in Traffic Crash Reconstruction.(#3183) He also has 150 ours of post graduate study in functional and developmental neurology.

His knowledge and lectures bridge the gap between accident reconstruction, mechanism of injury, human tissue response and pain transmission. He has participated in full scale human volunteer crash testing on multiple occasions with the Spine Research Institute of San Diego (in conjunction with Texas A&M Engineering Department) and the Collision Safety Institute, along with conducting his own crash test seminar in 2016. He is also an Advanced Graduate in Whiplash and Brain Trauma from the Spine Research Institute of San Diego. Dr. Barczyk lectures regularly to physicians, attorneys and judges regarding biomechanics, occupant risk and mechanism of injury.


Low Speed Crashes / Vehicle Dynamics

Josh Guthrie is a 24-year veteran of the Pennsylvania State Police. He is also a partner at Force Analysis and Multimedia Review, LLC which provides services relative to the analysis of police use of force incidents and the examination of digital video evidence. He is an A.C.T.A.R. accredited collision reconstructionist and specializes in 3D laser scanning, reverse projection photogrammetry, and speed from video analysis. He has also served as a patrol officer, instructor, and is currently assigned as a critical incident reconstructionist and multimedia specialist for his agency. During his time as an instructor, he has trained thousands of law enforcement officers in collision reconstruction and scene analysis. He provides support regarding the examination of digital evidence and the creation of court demonstratives for numerous District Attorney’s offices throughout the state of Pennsylvania.


Video Analysis for Speed, Etc.

Narayan Yoganandan, PhD, is Professor and Chairman of Biomedical Engineering in the Department of Neurosurgery and Professor of Biomedical Engineering at Marquette University. He has published over 220 peer-reviewed archival journal papers, 40 book chapters, 250 abstracts and conference proceedings, and 100 presentations. He is the senior editor of two books, entitled Frontiers in Head and Neck Trauma: Clinical and Biomechanical (1988, 743 pages) and Frontiers in Whiplash Trauma: Clinical and Biomechanical (2000; 589 pages).
