PhD in Computational Imaging for Cultural Heritage

The Faculty of Science and Leiden Institute of Advanced Computer Science (LIACS) are looking for candidates for a

PhD in Computational Imaging for Cultural Heritage (1.0 fte)

As a PhD student, you will be embedded in the research group Computational Imaging and Deep Learning (CIDL), part of the Leiden Institute of Advanced Computer Science (LIACS). As a team, we develop cutting-edge techniques for advanced computational imaging systems, combining expertise from Mathematics (Inverse Problems), Computer Science (Efficient Algorithms and High-Performance Computing), and Physics (Image Formation Modelling).

Your project is part of the FLEXART research project, which focuses on the development of new techniques for X-ray-based imaging of thin, elongated objects, such as paintings. In this collaborative project we team up with the Rijksmuseum in Amsterdam, and with researchers from Centrum Wiskunde & Informatica (CWI), the University of Antwerp and Cambridge University.

The main goal of your PhD project will be to develop novel image acquisition schemes and image reconstruction algorithms for using a combination of tomographic imaging and machine-learning based techniques. You will work with real data gathered from museum collection objects and will also design your own experiments to gather insights in the reconstruction of (paint) layers.

As a candidate, you must have a strong background in computational imaging and image processing, as well as excellent programming skills. In addition, you must have an understanding of or an interest in the physics of (X-ray) image formation.

Research at our faculty and institute

The Leiden Faculty of Science is a world-class faculty where staff and students work together in a dynamic international environment. Our people are driven by curiosity to expand fundamental knowledge and to look beyond the borders of their own discipline. The research carried out at the Faculty of Science is diverse, ranging from artificial intelligence, computer science, mathematics, astronomy, physics, chemistry and bio-pharmaceutical sciences to biology and environmental sciences. The faculty has grown strongly in recent years and now has more than 1,300 staff and almost 4,000 students. We are located at the heart of Leiden’s Bio Science Park, one of Europe’s biggest science parks, where university and business life come together.

The Leiden Institute of Advanced Computer Science (LIACS) is the Artificial Intelligence and Computer Science Institute of the Faculty of Science of Leiden University. We offer courses at the Bachelor and Master of Science level in the core areas of Artificial Intelligence, Computer Science, and Data Science, and also in the interdisciplinary areas of ICT in Business, Media Technology and Creative science, and Bioinformatics. According to an independent research visitation, we are one of the foremost computer science departments of the Netherlands. Our people and our focus on collaboration in a caring atmosphere are dear to us. We strive for excellence in a caring institute, where excellence, fun, and inclusiveness go hand in hand. We offer a clear and inviting career path to young and talented scientists with the ambition to grow.

The city of Leiden

Leiden University is one of Europe's foremost research universities. Leiden is a lively and beautiful city with a central location in Europe, at only 17 minutes from Schiphol International Airport. It is a very international city where almost everybody speaks English, candidates need not be afraid of the language barrier. Leiden is a typical historic university city, hosting the oldest university in the Netherlands (1575). The University permeates the local surroundings; University premises are scattered throughout the city, and the students who live and study in Leiden give the city its relaxed yet vibrant atmosphere. Today, with some 27,000 students, 5,500 staff, 16 Nobel prizes, more than 100 nationalities and a budget of more than 550 million Euros, it is one of the largest comprehensive universities in Europe. This prominent position gives our graduates a leading edge in applying for academic posts and for functions outside academia.

Terms and conditions

We offer a full-time appointment of initially one year. After a positive evaluation of the progress of the research, teaching evaluations, personal capabilities and compatibility, the appointment will be extended for another three years. The salary will be in the range of € 2.901,= to €3.707,= gross per month, subject to national taxation and social contributions.

Leiden University offers an attractive benefits package with additional holiday (8%) and end-of-year bonuses (8.3%), training and career development. Our individual choices model gives you some freedom to assemble your own set of terms and conditions.

All our PhD students are embedded in the Leiden University Graduate School of Science. Our graduate school offers several PhD training courses at three levels: professional courses, skills training and personal effectiveness. In addition, advanced courses to deepen scientific knowledge are offered by the research school.

Diversity and work-life balance

Leiden University is strongly committed to diversity within its community and especially welcomes applications from members of underrepresented groups. LIACS is a highly diverse institute, in culture, background, and gender. We stand for excellence in a caring Institute. We wish to reflect society in all aspects, as we believe that this improves the dynamics in our organization. Therefore, we support and understand the need for a work/life/family balance and consequent varying working hours and places. We believe that doing good science is fun and goes hand in hand with a friendly culture. In the Netherlands, a maternity allowance is standard for 16 weeks. Child care is available at and near the Bio Science Park.
