Arjo is a tenured lecturer in the Biomechanical Engineering department of the Faculty of Mechanical Engineering at TU Delft. He is also a coordinator of the Co van Ledden Hulsebosch Center for forensic science and medicine. Arjo has been doing research on, lecturing about and coordinating graduation projects on clinical technology since 2006 and on Engineering for Forensics since 2008. While doing his PhD on rigidifiable shaft-guides for flexible endoscopes, he simultaneously started investigating and improving the reliability of trace collection methods used on rape victims. This led him to combine the fields of biomechanical engineering and forensics into the Engineering for Forensics research line.
He has been working as an expert investigator on various bacteriological outbreak cases related to the design and use of medical devices, affecting world-wide changes in device design and hospital hygiene policies. He currently cooperates closely with national and international forensic institutes and the Dutch police to develop and improve forensic tools and methods. He is one of the founders of the “TU Delft Forensics” community for Forensic Engineering and Engineering for Forensics
