PhD Position Harnessing Nonlinear Dynamics: From Data-Driven Discovery to Engineering

Nonlinear dynamics lies at the centre of many mechanical systems, from large-scale structures to nanoscale devices. Yet, predicting and exploiting nonlinear behaviour,  particularly the role of modal couplings in energy transfer and dissipation, remains a fundamental challenge. This PhD project offers a unique opportunity to tackle these two complementary perspectives.

In the first direction, you will develop advanced system identification techniques that combine nonlinear dynamics theory with machine learning tools. The goal is to extract governing equations directly from experimental data, enabling accurate prediction of nonlinear phenomena such as modal interactions and dissipation pathways across scales: from complex structural assemblies to nanomechanical resonators.

In the second direction, you will explore the geometric design of nonlinear systems. Using nonlinear reduced order modelling (ROM) integrated with optimization algorithms, you will design structures that deliberately harness modal couplings to exhibit tailored nonlinear behaviour, with direct applications in ultrasensitive resonant sensing.

Together, these approaches will provide both data-driven methods for uncovering nonlinearities and dissipation mechanisms, and design strategies for exploiting them. The project sits at the interface of nonlinear mechanics, computational modelling, and machine learning, and is well-suited for candidates eager to develop computational frameworks for next-generation structural dynamics and nanomechanical technologies.

The vacant position is in the Dynamics of Micro and Nanosystems (DMN) group. The group focuses on exploiting dynamics to create technologies that can lead to new products in the fields of scientific instrumentation, consumer electronics and healthcare. Our research spans from measuring and manipulating materials at the micro and nano scale, to the design of world-class sensors and actuators.

You will be working in an international environment in one of the leading technical universities of Europe, with access to state-of-the art computational facilities. You will be contributing to a challenging topic related to a European Research Council (ERC) Consolidator and a Dutch Research Council (NWO) grant.

As a PhD student your tasks will include but not limit to:

• Mastering concepts from nonlinear dynamics, data-driven model discovery, and computational design.
• Extending our existing theoretical frameworks in investigating design optimization and nonlinear parameter estimation.
• Contributing to the teaching and assisting with dynamics relevant courses at the department.
• Writing a PhD thesis, publishing in renowned computational journals, and presenting your research at international meetings.

We are looking for applicants with the following qualifications:

• MSc university degree in physics, mechanical engineering, or mathematics.
• High motivation for teamwork and good communication skills.
• Experience in nonlinear dynamics and /or random vibrations and computational design.
• Good programming skills with experience in reduced-order modelling techniques and data-driven symbolic regression tools is a plus.
