Dr. Giachetti has experience in biomechanics and mechanical system design. He has used biomechanics to investigate human muscular coordination in the lower limbs with a specific emphasis on balance and posture. He has also utilized and developed biomechanical and analytical tools to investigate occupant induced whole body vibrations in the transportation industry.
Prior to joining Exponent, Dr. Giachetti worked in the Biomechanics laboratory at the University of Wisconsin – Madison, where he focused his academic training, research, and, teaching in pursuit of characterizing how humans exert force on their environment using their lower limbs. At the Biomechanics Research Laboratory at the University of Illinois at Chicago, he assisted in the analysis and validation of a total knee replacement through the use of finite element modeling and analysis in ANSYS to determine contact stresses within the artificial joint.
Dr. Giachetti’s academic emphasis extended beyond Biomechanics and involved intensive study in Mechanical Engineering curricula, including advanced courses in linear and nonlinear dynamics, stress analysis and continuum mechanics, and vibrations. Dr. Giachetti also has work experience in the field of mechanical design, working on projects such as: the validation of the ultrasonic welding manufacturing process of assay trays, the design of steel coiling machinery, and the general design of custom lifting equipment.
Dr. Giachetti has extensive experience designing and programming data analysis and acquisition software in LabVIEW. His experience in programming not only includes real time analysis software, but also, the implementation of multiple, simultaneous acquisition sources. These acquisition systems have included cameras, accelerometers, serial devices, force plates, force transducers, and GPS devices. His programming expertise also extends to customized 2-D motion capture solutions and the implementation of the IMAQ and Vibration packages available for LabVIEW.
