The Department of Mechanical Engineering at Eindhoven University of Technology (TU/e) is offering a PhD position focused on the contract-based design of complex dynamical systems. This research is situated within the Dynamics and Control section, which is renowned for its world-class research and strong ties to the high-tech industry, particularly in the Brainport region of the Netherlands. The project aims to simplify and enhance the design process of complex dynamical systems—such as semiconductor machines, robots, and other high-tech equipment—by developing novel tools based on contract-based system theory. These tools will automate and improve the translation of system-level requirements into module-level specifications, addressing both time- and frequency-domain behaviors. The research is highly interdisciplinary, combining elements of mechanical engineering, systems and control theory, applied mathematics, and mechatronics. The successful candidate will join a team of four PhD students (two at TU/e and two at the University of Groningen) and will have opportunities to collaborate with leading high-tech companies in chip manufacturing and robotics. The position is jointly supervised by Professor Nathan van de Wouw (TU/e) and Dr. Bart Besselink (University of Groningen), offering a strong academic and industrial network. The PhD candidate will have access to graduate courses at the Dutch Institute of Systems and Control (DISC) and the Engineering Mechanics Research School (EM), and will be part of a vibrant research community of over 60 members. Applicants should hold a master’s degree in systems and control, mechanical engineering, or applied mathematics, with a strong background in dynamical systems and control theory. Experience with Matlab or Python, and an affinity for mechatronics or robotics, are required. The position offers a four-year full-time contract, with a competitive salary (scale P: €3,059–€3,881), year-end bonus, vacation pay, pension, parental leave, and additional allowances. International candidates may benefit from the 30% tax compensation scheme. The application process is online only, and candidates must submit a CV, motivation letter, academic transcripts, and a brief description of their MSc thesis or relevant research. The vacancy will remain open until filled, with a formal deadline of November 20, 2025.
