Senior Biomechanist (Accident Reconstruction)

The Role: The Senior Biomechanist works with engineering staff in human-injury impact analysis in vehicular accidents, reconstructing vehicular accidents, consulting and analysis of injuries related to premises liability and slip-and-fall incidents, and requires extensive experience in forensic biomechanical analyses. This role performs investigations focusing on musculoskeletal biomechanics to determine the relationship between accident modes and injuries and requires evaluation and analysis of biomechanical systems, including voluntary and involuntary human motions, assessment of situations leading to the accident, and reconstructing the accidents. The role requires familiarity with legal depositions, working with attorneys and claims adjusters. Additionally, the ideal candidate has experience working with network of external clientele (e.g. lawyers, insurance carriers and adjusters, etc.) and is experienced with building, establishing, and maintaining rapport with this network.

The role is fully remote open to candidates located anywhere in the United States. Candidates located in the listed states are encouraged to apply.

In This Role, You Will:

Inspect and measures vehicles.

Provide expert testimony at trials, depositions, or other legal proceedings and communicates investigative findings in a manner easily understood by technical or non-technical audiences.

Use computer models to reconstruct accidents and to measure load and injury levels.

Conduct detailed inspections of vehicles and accident sites and accurately analyzes crash sequences to identify contributing factors and the induced loading on the occupants.

Review various documents to identify relevant information for an accident reconstruction or biomechanical engineering analysis (includes police reports, medical records, depositions, expert reports, legal pleadings and discovery documents, videos, photographs, etc.)

Perform simulations of vehicular collisions using advanced collision reconstruction software such as PC-Crash.

Evaluates the effects of impact forces on occupants as a result of vehicular accidents.

Determine human injury mechanisms in vehicular accidents and premises liability cases such as slip-and-fall accidents.

Perform accident reconstructions of single-vehicle rollovers, single-vehicle impacts with fixed objects, and multi-vehicle collisions (frontal, side, rear, and sideswipe).

Utilize engineering principles to calculate factors such as impact and departure speeds, collision forces, and trajectories of vehicles.

Compare calculations with crash test reports of similar collisions to correlate damages based on calculated velocities.

Review papers and journals related to vehicular accident reconstruction to understand and advance the scientific techniques used in reconstruction work.

Provide written conclusions of findings to assist others in understanding the evidence or in determining the facts at issue.

Take an active role in marketing YA Engineering Services to clients and to the forensic engineering community.
