Experience

Research associate — University of Oxford — 2023-2025

I studied the performance of natural gas pipelines when transporting hydrogen. Hydrogen enters the pipeline steels, which significantly reduces the fracture properties. I used advanced multi-physics models to predict the hydrogen failure pressures of pipelines.

  • Developed a thermal-metallurgical-mechanical welding simulation framework that predicts heterogeneous properties, microstructure constituents, hardness maps, and residual stresses in pipeline welds.
  • Employed elastic-plastic phase field fracture models coupled to hydrogen diffusion to predict the failure pressures of flawed pipelines. The results of the welding model were used as initial input.
  • Connected advanced simulation results to industrial standards for defect assessments to provide guidelines when using these standards in the presence of hydrogen.
  • In cooperation with the Electric Power Energy Research Institute (EPRI).

During my period at the University of Oxford I was associated with the Mechanics of Materials Lab lead by Emilio Martínez-Pañeda, in the Department of Engineering Science.

Web developer — D-web solutions — 2016-2018

This was a part-time job while obtaining my MSc. degree. I mainly worked on the back-end development of websites. Programming languages I used included PHP, SQL, Javascript and HTML.

Education

Doctor of Philosophy (PhD) — Eindhoven University of Technology — 2019-2023

During my PhD I studied the deformation of dual-phase steel microstructures using advanced plasticity models. Such steels are widely used in the automotive industry due to an excellent combination of strength and ductility.

  • Developed the discrete slip plane model, a crystal plasticity model that introduces heterogeneous properties in single grains. The model accurately captures the stochastic and heterogeneous deformation that is observed in the deformation of steels at the microscale.
  • Conducted integrated numerical-experimental studies on dual-phase steel microstructures and its constituents. This was done in close collaboration with an experimental colleague. Experiments were used to validate simulations, while simulations were used to elucidate experimental observations.

I conducted my PhD research in the Mechanics of Materials group, at the Department of Mechanical Engineering, under the supervision of Ron Peerlings, Johan Hoefnagels, and Marc Geers.

Master of Science (MSc) — Mechanical Engineering — Eindhoven University of Technology — 2016-2018

  • I obtained my degree with a specialization in Mechanics of Materials. I followed courses related to solid mechanics, fluid mechanics, finite element methods, and scientific computing.
  • Internship: National University of Singapore
    I worked on gradient damage models for accurately predicting the fracture of concrete. The gradient damage models were implemented using different equivalent strain measures, which were tested against experimental data.
  • Master thesis: Immersed methods for modeling complex microstructures of composite materials
    In my graduation project I worked on a computational framework which sets up simulations of composite microstructures based on CT-scan data. I developed an algorithm that extracts the fiber directions from the images. The simulations were performed using the finite cell method, which is an immersed method that avoids needing a conforming mesh.

Bachelor of Science (BSc) — Mechanical Engineering — Eindhoven University of Technology — 2013-2016

  • Graduation project on locally resonant acoustic metamaterials. I studied the effects of visco-elastic material properties on the wave attenuation of the material.

Pre-university education (VWO) — Rythovius College, Eersel — 2013-2016

Skills

Project skills

I have been a part of two large projects, namely my PhD project and my postdoc project. In addition, I have played a role in numerous student projects. During these projects I have learned valuable skills.

  • Project management
    Planning, forecasting, and executing of longer projects (several years) and shorter projects (several months).
  • Communication
    Communication of results on various levels. Research outcomes were communicated to the scientific community via scientific papers and conferences. In addition, communication to non-expert stakeholders involved in projects required presenting project progress in an easy manner, focusing on project outcomes and lessons learned.
  • Collaboration
    I have collaborated extensively with colleagues, for example, with experimentalists. This required good coordination and clear communication.
  • Supervision
    I have supervised several master and bachelor graduation projects, which required keeping overview of a project where the work is done by other people.

Finite element software

  • ABAQUS
    I have several year of experience running various types of simulations in ABAQUS. This includes coupled thermal-mechanical analyses, fracture mechanics simulations, and self-implemented advanced material models (e.g. phase-field fracture). I have used numerous Fortran user-subroutines to implement advanced material behavior or boundary conditions and am familiar with the ABAQUS Python scripting language.
  • Msc.Marc/Mentat
    I have extensively used Msc.Marc/Mentat during my PhD research. This included conducting crystal plasticity simulations, implemented via Fortran user-subroutines, and the implementation of advanced boundary conditions for representative volume elements (e.g. symmetric).
  • Moose
    I have implemented several material models in Moose, an open-source finite element framework written in C++. Such open-source frameworks often provide more flexibility than commercial software.

Programming

  • Python
    Is my go-to scripting language. I have used Python for more than 5 years for numerous pre- and post-processing scripts, data analysis scripts, and small simulation programs.
  • C++
    I have used C++ for writing finite element code. This includes small programs build from scratch and extensions of larger finite element frameworks using libraries such as Moose and Jem/Jive.
  • Fortran
    I have extensively used Fortran to extend the capabilities of commercial FE software via user-subroutines.
  • Matlab
    I have used Matlab throughout my education and PhD period.

Teaching

I have helped with teaching several courses to students. I have been extensively involved in the course Numerical Methods For Solid And Fluid Mechanics. Additionally, I have been involved in the courses Experimental And Numerical Skills and Micromechanics.
