Mr. Ken Iliadis is a senior scientist at MEA Forensic and a member of the Collision Reconstruction group in Toronto. Over his 24-year career doing forensic work, Ken has investigated thousands of car, truck, and bus collisions involving serious and catastrophic injuries. Ken also works on accidents involving snowmobiles, ATVs, and other off-road vehicles. Ken is a licensed professional physicist and peace officer and has testified as an expert witness in court many times.

After graduating from the University of Western Ontario with a Bachelor’s degree in Physics, Ken was involved in a study of first-generation airbags that found they deployed with excessive force. As a direct result, manufacturers introduced depowered second-generation airbags, which decreased the number of injuries and deaths. Ken continues to do research at MEA. His published work on the acceleration and braking of snowmobiles has made him a leader in reconstructing accidents involving these kinds of vehicles.

Ken’s experience helps him identify all of the factors that could have contributed to a collision. “I’ve learned that it is rare for an accident to happen because of one, isolated factor,” he says. “Often, there is a perfect storm: one driver was speeding, another entered an intersection on a yellow light or was looking at their phone. It’s often not just about the speed of one car.” He is also focused on communicating the results of his analyses in a clear way, and often uses computer simulations and animations to present his results. “As someone who does a lot of animation, I love that software is getting more powerful and allowing for more realistic depictions,” he says.

Professional Experience

  1. MEA Forensic Engineers & Scientists
    Senior Scientist, 2008 to Present

    Responsible for the technical assessment of motor vehicle accidents with expertise in collision severity, collision sequence, seat belt use and effectiveness, vehicle crush and dynamics, illumination and visibility, road design, bicycle/pedestrian accidents, computer simulation/animation, and photogrammetrical analysis.

  2. Special Investigations Unit, Ministry of the Attorney General, Toronto, ON
    Senior Reconstructionist, 2007 to Present

    Employed on an as-needed basis. Responsible for the technical assessment of motor vehicle accidents, where the police are involved and a civilian has sustained either serious or fatal injuries.

  3. Hastings Boulding Correia Consulting Engineers and Scientists, Mississauga, ON
    Associate/Partner, 1998 to 2008

    Involved in the reconstruction of hundreds of high-speed and complex motor vehicle accidents. Qualified and testified to give expert evidence as a Forensic Scientist in the field of Accident Reconstruction on civil and criminal matters in the Superior and Provincial Courts of Ontario. Conducted research in areas such as the utilization of automotive event data recorders.

  4. Iliadis and Associates, Toronto, ON
    Accident Investigation and 3-D Animation, Sole Proprietor, 1996 to 2002

    Consulting work focusing on the reconstruction of motor vehicle collisions and creating 3-dimensional animations of the collisions.

  5. Ryerson University, Toronto, ON
    Transport Canada Research Contract – Accident Investigator, 1995 – 1998

    Technical responsibilities included collision investigation/reconstruction and injury analysis, with the intent to determine the effectiveness of safety related vehicle components.

Research Activities

  1. Completed over 500 tests assessing the acceleration and braking capabilities of modern snowmobiles. Acceleration tests were performed at ¼, ½, and full throttle. Braking tests were performed under locked track conditions as well as rolldown (engine braking) with engine power ON and power OFF. It was found that a modern snowmobile can accelerate on groomed/packed snow at rates similar to a motorcycle on dry roads, while its maximum braking rate is closer to about half that of a passenger car on dry roads.
  2. Completed an in-depth study involving automotive “black box” data recorders. Several staged crash tests were completed and analysed. Results from the vehicle crash data recorders were compared with calibrated instrumentation in order to determine the validity of the data downloaded from the crash data recorders.
  3. Completed a comprehensive study evaluating the effectiveness of modern roundabouts when compared to contemporary intersections, in terms of safety and traffic flow. The study included a detailed assessment of the Coe Hill roundabout in Toronto, ON.
  4. Extensive research and testing was conducted using 3-dimensional animation software as an analytical tool and a presentation method for collision reconstruction. Video and still-photographs were commonly used as backgrounds to the animations. Forensic animations have been presented at the Ontario Science Centre, the Ontario Provincial Police training headquarters, and at the Canadian Multidisciplinary Road Safety Conference.
  5. Aerial photography is becoming a routine tool in forensic diagrams. Stock aerial photographs of urban centers are relatively easy to obtain, however, photographs of rural areas are not. A research project was completed which involved flying to remote locations, taking orthographic photographs and rectifying these photographs using survey measurements.
  6. Led a research team involved in a nation-wide study on the effectiveness of first-generation airbags. The primary focus of the research was to compare crash severity versus occupant injury. A direct result of this research was the depowering of airbags by the manufacturers (second-generation airbags), leading to a significant decrease in injuries and deaths to the general public due to overly aggressive airbag deployments.
