Dr. Mazzarella has Accident Investigation training through Northwestern University School of Public Health which allows for speed estimates, crush estimates, PDOF determination, and accident mapping (skid marks, gouges, yaw marks, grooves, scrapes, etc).  In addition, Dr. Mazzarella has Accident Reconstruction training through a Pedestrian crash course via Michigan State University and training through the Toronto Police College which included slide to stop calculations, fault, human factors, series of events determination, vehicle dynamics, at scene drag factor and grade determinations, roadway evidence/analysis/evaluation, tire mark analysis and evaluation, forensic mapping, scaled diagrams,  time distance determinations, restraint system evaluation and investigation, dangerous goods, at scene photography, evidence retrieval and analysis and at scene accident investigation and outdoor scene investigation.  

Dr. Mazzarella also has event data recording specific training including being certified in crash data retrieval and crash data analysis.  This certification allows for downloads of the vehicle data after an accident and can include topics such as speed at the time of collision, usage of brakes, brake lights, seatbelt usage, occupant number, braking, etc.  

Lastly, Dr. Mazzarella has a certification in motor vehicle crash forensics risk analysis which he completed while studying live full scale human volunteer crash testing.  This training allows for a determination of occupant kinematics and biomechanics during a crash as well as seatbelt / restraint system kinematics, air bag deployment and safety, bumper standards, oblique impact vector kinematics, frontal impact vector kinematics, rear impact vector kinematics, lateral impact vector kinematics, heat restraint geometry risk/safety,analysis, bullet vs target vehicle collision comparison and analysis, roll over research and child safety.  

Dr. Mazzarella’s has taken several post graduate courses covering over 300 hours of training in accident investigation, reconstruction and crash forensics from the following:


  1. Spine Research Institute of San Diego
  2. Michigan State University 
  3. Northwestern University 
  4. Toronto Police Services
