Dr. Joost Op ‘t Eynde is a biomedical and mechanical engineer at Engineering Systems Inc. (ESi) in the Irvine, California, office. Dr. Op ‘t Eynde has related expertise in blunt impact trauma, body armor and helmet systems, spine injury biomechanics, blast injury biomechanics, injury risk development, injury detection, and biomechanical experimental testing (cadaver, anthropometric test device, and animal).
Prior to joining ESi, Dr. Op ‘t Eynde earned a Ph.D. and M.S. in Biomedical Engineering from Duke University while conducting research in the Injury Biomechanics Laboratory. For his dissertation research, Dr. Op ‘t Eynde investigated injury risks and mechanisms related to behind armor blunt trauma. He also has extensive research experience in spine injury biomechanics, personal protective equipment for blast and blunt impact, blast neurotrauma, viscoelastic material properties, acoustic injury detection, biomechanical scaling, and injury mechanisms.
Dr. Op ‘t Eynde has presented his engineering research at international conferences and is published in peer-reviewed journals and conference proceedings, including PLOS One, International Research Council on Biomechanics of Injury, and Personal Armour Systems Symposium.
