Job Description

1 - Working at the VUB

For more than 50 years, the Vrije Universiteit Brussel has stood for f reedom, equality and solidarity, and this is very much alive on our campuses among students and staff alike.

At the VUB, you will find a diverse collection of personalities: innovators pur sang, but above all people who are 100% their authentic selves With some 4,000 employees, we are the largest Dutch-speaking employer, in the private sector, in Brussels; an international city with which we are only too happy to connect and where (around) our 4 campuses are located.

Add to this our principle of free research - in which self-reflection, a critical attitude and an open, creative mind around scientific and social issues are central - and you have a university that is fundamentally groundbreaking and pioneering in education and research. In short: the VUB all over again

Moreover, the VUB is a member of EUTOPIA, an alliance of like-minded European universities, all ready to reinvent themselves.

2 - Position description

The Faculty of Engineering, Department Electronics and Informatics, Research Group Electronics and Informatics: Research – Development - Innovation is looking for a PhD-student with a doctoral grant

More concretely your work package, for the preparation of a doctorate, contains:

Shape the future of immersive visual technologies through optical, computational, and machine‑learning innovation.

We are a university research group at imec-VUB in Brussels, with expertise in optical imaging systems and signal processing and the Department of Electronics and Informatics ( ETRO), an imec research group at the Vrije Universiteit Brussel ( VUB), has an open research position for a talented and motivated researcher.

Project

We invite applications for a full-time PhD position in the rapidly evolving field of computational holography and advanced photonic display systems The project aims at redefining what is technologically possible in holographic visualization, pushing beyond today’s limitations in field of view, resolution, and visual realism.

This PhD position is funded by larger, 4-year WEAVE project funded by Research Foundation Flanders – Fonds voor Wetenschappelijk Onderzoek Vlaanderen (FWO) and the National Science Centre Poland - Narodowe Centrum Nauki (NCN). It involves researchers from the Vrije Universiteit Brussel/imec and Warsaw University of Technology, under supervision of Prof. Peter Schelkens and Prof. David Blinder, and respectivily. Prof. Tomasz Kozacki.

Traditional 3D displays are constrained by optical inconsistencies such as the vergence‑accommodation conflict, which leads to visual discomfort and restricts long-term use. Holography resolves this limitation by reproducing the full wavefront of light, enabling natural depth cues and fatigue-free viewing. However, moving from classical holography to ultra-wide-angle, ultra-high-resolution holography presents significant challenges. These include enormous data bandwidths, sophisticated optical control, advanced rendering pipelines, and new algorithms that can tightly integrate physical hardware, sensors, and computational models.

This PhD position is centered on addressing these challenges through innovative computational methods, combining optical system design, signal processing, machine learning, and optimization. You will contribute to the development of new solutions for hologram recording, generation, quality assessment, and real-time rendering.

This is an exciting opportunity for a motivated researcher who wants to contribute to a transformative technology area at the intersection of physics, computation, and human perception You will join a dynamic multidisciplinary international team working on algorithmic, computational, and physical-layer solutions for emerging holographic systems. The results of this project have the potential to shape future consumer, industrial, medical, and scientific visualization systems.

Research themes:

The PhD student will contribute to several of the following topics:

• Computer-generated holography (CGH);
• Optical system analysis and simulation;
• Developing AI/ML algorithms;
• Perceptual and objective visual quality assessment for holograms.

For this function, our Brussels Humanities, Sciences & Engineering Campus (Elsene) will serve as your home base.

3 - Profile

What do we expect from you?

•  You hold a Master’s degree in Photonics, Electrical Engineering, Applied Physics, or Computer Science.

• You have a solid understanding of optical wave propagation, Fourier optics, or computational imaging;
• You have strong skills in digital signal processing (DSP), including familiarity with machine learning or deep learning;
• You have proficiency in scientific programming (e.g., Python, MATLAB, C/C++, or similar).

• You have not performed any works in the execution of a mandate as an assistant, paid from operating resources, over a total (cumulated) period of more than 12 months.

• As a (non-)EEA national, meet the conditions for obtaining a valid permit for VUB and comply with the VUB residence requirements. More info here

The VUB wants to be a reflection of the society where everyone's talent is valued, regardless of gender, age, religion, skin color, migration background, disability and neurodiversity.

4 - Offer

Are you going to be our new colleague?
