Marzieh M. Ardestani, Ph.D., M.S., ACTAR

Senior Consultant

Dr. Ardestani is a Senior Consultant at Engineering Systems Inc. (ESi). She is a certified accident reconstructionist (ACTAR) with specialized expertise in passenger vehicles, commercial tractor-trailers, and Event Data Recorder (EDR) and Heavy Vehicle Event Data Recorder (HVEDR) downloads and analysis.

Dr. Ardestani holds a Ph.D. in mechanical engineering, a master’s in electrical engineering, and a bachelor's in biomedical engineering, providing her with a diverse and robust engineering foundation.

Dr. Ardestani focuses on traffic accident investigation and crash reconstruction, handling a wide range of cases involving passenger vehicles, commercial tractor-trailers, recreational vehicles, marine accidents, and incidents involving pedestrians, bicyclists, and motorcyclists.  

Leveraging her expertise in electrical and mechanical engineering, she also evaluates vehicle safety systems, such as seatbelts and airbags in passenger vehicles, and heavy vehicle air brake systems. Her expertise  also includes vehicle dynamics instrumentation, mechanical testing, data acquisition and analysis, and 3D laser scanning.

Dr. Ardestani has extensive experience designing and executing experiments involving vehicles and marine environments. Her work captures occupant kinematics and human-machine interactions. She is also adept at data analysis, signal processing, and video analysis, including dash cam and surveillance video interpretation, as well as 3D modeling of accident scenes using laser scanning.

Her graduate studies focused on impact biomechanics, injury mechanisms, injury tolerance, and musculoskeletal biomechanics. Dr. Ardestani has significant experience in mathematical modeling, finite element methods, and computational simulations, including crash simulations in HVE and PC-Crash, and human kinematic simulations in MADYMO.
