About this position
PhD opportunity at Vrije Universiteit Brussel (VUB), Belgium in optical fibre sensing, photonics, and ultra-high-pressure rheometry.
The Faculty of Engineering, Department Toegepaste natuurkunde en fotonica, and the Research Group Brussels Photonics (B-PHOT) are recruiting a PhD student with a doctoral grant for the RheoLub project, funded by the Research Foundation - Flanders (FWO). The project focuses on understanding the behaviour of industrial lubricants under extreme operating conditions and developing advanced experimental and modelling methods for ultra-high-pressure rheometry.
Your research will centre on the development and validation of miniature optical fibre sensors for measuring pressure and temperature in a new generation of rheometers. The work includes designing sensor integration strategies, developing arrays of Fiber Bragg Grating (FBG) sensors, exploring pressure-sensitive fibre concepts such as the Butterfly microstructured optical fibre, calibrating sensors in high-pressure test setups, and processing spectral data for pressure/temperature compensation.
You will work closely with partners at Ghent University, who are developing the rheometer cartridge, thin-film reference sensors, and digital-twin-based methods for extracting material properties. The position is based at the Brussels Humanities, Sciences & Engineering Campus in Etterbeek, with additional work at the Photonics Innovation Center in Pajottegem depending on experiments and meetings.
Eligibility details are not fully specified in the post, but the role is clearly aimed at a PhD researcher with interest in photonics, sensing, experimental calibration, and data analysis. Limited teaching duties may be included, such as supervising practical sessions or Master’s theses.
Apply through the official VUB jobs portal using the link provided in the post. No deadline is stated in the text shown.
