Job description

The Database and Formal Methods & Tools groups at the University of Twente seek two PhD candidates for SEQUOIA: Smart maintenance optimization via big data & fault tree analysis, a project funded by the Dutch Technology Foundation STW, and the companies ProRail and NS. ProRail is responsible for the Dutch railway network, including its construction, management, maintenance, and safety; NS has the same responsibility for the Dutch train fleed. The project is led by Dr. Mariëlle Stoelinga, Prof.dr. Joost-Pieter Katoen and Dr. Djoerd Hiemstra.

SEQUOIA aims to improve the reliability of the Dutch railroads by deploying big data analytics to predict and prevent failures. Its scientific core is a novel combination of machine learning, fault tree analysis and stochastic model checking. Key idea is that big data analytics provide the statistics on failures, their correlations, dependencies etc. and fault trees provide the domain knowledge needed to interpret these data. The project outcome aims at fewer train disruptions and delays, lower maintenance cost, and more passenger comfort.

The project involves an intense cooperation with the RWTH Aachen University and with various engineers from ProRail and NS. The PhD candidates will spend a portion of their time at the ProRail / NS sites in Utrecht.

Key project deliverables are efficient analysis algorithms and a workable tool to be used in the ProRail context. For more information about the project,
see: fmt.cs.utwente.nl/research/projects/SEQUOIA/


The candidate should have an MSc degree in Computer Science, Mathematics, Data Science or an equivalent qualification.

We seek one candidate with a background in data science and big data analytics. He or she should have a thorough background in (predictive) modeling, have ample experience with software development and tools (e.g. R, python, Hadoop, , Hyve, Jupyter, Zeppelin) and/or industrial case studies. Speaking Dutch, or the ability to learn it fast is a prerequisite.

We seek another candidate with a background in formal methods or reliability engineering. The ideal candidate has a thorough theoretical background, and should have ample experience with software development and/or industrial case studies.

Further we ask for good communication and collaboration skills.

New technology which drives change, innovation and progress in society. The University of Twente is the only campus university in the Netherlands; divided over six faculties we provide more than fifty educational programmes. The University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research.

The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) comprises three disciplines that shape Information and Communication Technology. ICT is more than communication. In almost every product we use mathematics, electronics and computer technology and ICT now contributes to all of societies' activities. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders. The research which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes MESA+, CTIT and MIRA.
