Rate My Professor Marijn Nijenhuis

Marijn Nijenhuis is an Assistant Professor in the Precision Engineering group at the University of Twente's Faculty of Engineering Technology. He obtained both his master's degree and PhD in mechanical engineering cum laude from the University of Twente, defending his doctoral thesis, 'Spatial Flexure Mechanism Analysis: Energy-Based Geometric Stiffness Modeling,' in 2020. During his PhD in the Precision Engineering laboratory within the Department of Mechanics of Solids, Surfaces and Systems, his research centered on optimizing large-range-of-motion spatial flexure joints through topology synthesis methods. Since 2020, Nijenhuis has continued his academic career at the same institution, focusing on elastic mechanisms at both element and system levels. He develops flexible multibody simulation software to design highly predictable, frictionless, and backlash-free mechanisms for high-precision applications.

Nijenhuis's research specializations include flexure mechanisms, multibody simulation of large-deflection mechanisms, geometrically non-linear beam theory for active beams, piezoelectric damping of position-dependent parasitic vibrations, and rectilinear flexure stages with near-zero parasitic shift. A notable outcome of his work is the T-Flex, a fully flexure-based hexapod providing a large range of motion combined with sub-micron positioning precision. His contributions have earned significant recognition: in 2022, he received the Early Career Award from the American Society for Precision Engineering, the first such award to a non-US recipient; in 2024, he was granted a Veni award of up to €320,000 by the Dutch Research Council to study temperature effects in precision machines, enabling more accurate and cost-effective systems. With over 50 research outputs and 184 citations on Google Scholar, key publications include 'A beam element with arbitrary active cross sections for multibody simulation of large-deflection flexure mechanisms' (2025, Multibody System Dynamics), 'A geometrically non-linear beam theory for active beams with arbitrary cross-section' (2025, Computers & Structures), 'Gain margin constrained H2 and H∞ optimal Positive Position Feedback control for piezoelectric vibration suppression' (2025, Journal of Sound and Vibration), and 'Near-Zero Parasitic Shift Rectilinear Flexure Stages Based on Coupled n-RRR Planar Parallel Mechanisms' (2025, Machines).
