Stage vacatures in Leiderdorp

Leiden University was founded in 1575 and is one of Europe’s leading international research universities.

Applying is possible up to and including: 29 juni 2026

We are seeking individuals with a curiosity‑driven research record who work at the intersection of machine learning (ML) and quantum many‑body physics. We are also happy to work with experts in one of the two fields who are committed to learning the other. Moreover, we look for interest in developing interpretable, reliable, and scalable ML methods, neural quantum states, understanding the simplicity bias of overparameterized neural networks, or applying them to quantum systems, such as ultracold quantum simulators.

In this position, you will be encouraged to identify and tackle important challenges in quantum simulators, taking advantage of existing collaborations with leading experimental groups. You may join (and lead) existing collaborations aiming at scalable and practical Hamiltonian learning and detecting quantum phases of matter and their order parameters in exotic systems. You may help to explore the energy landscapes of neural quantum states or the simplicity biases of neural networks. You will be given scientific freedom to shape your own research agenda and will be supported by structured mentoring that includes career development plans tailored to your goals after the postdoctoral stage. The contract must start on December 2026 or earlier.

The successful candidate will work with Dr. Anna Dawid and her research team.

• Conduct rigorous research at the intersection of ML and quantum physics.
• Actively participate in regular group and one‑on‑one meetings.
• Co‑supervise Bachelor’s, Master’s, and PhD students.
• Present research results to the scientific community at international conferences and through publications.

• Ph.D. Degree in physics, computer science, or a related field.
• Good publication record in ML or quantum physics; a publication record in ML applied to scientific problems is a bonus.
• Good programming skills in Python; familiarity with PyTorch or Tensorflow is a bonus.
• High proficiency in spoken and written English.
• A team player who can communicate well also across scientific fields and teams.
• A creative, curiosity‑driven scientist with an open mindset.

• Full‑time two‑year term position for initially one year, with extension after positive evaluation under the CLA of Dutch Universities.
• Salary between €3,546 and €5,538 gross per month (Pay scale 10).
• Holiday allowance (8%), end‑of‑year bonus (8.3%), and attractive pension scheme at ABP.
• Full reimbursement of public transport commuting costs for home‑to‑work travel.
• Flexible working hours; minimum of 29 leave days per full‑time working week of 38 hours; options to accrue extra leave or exchange hours.
• Options for secondary employment conditions, sabbatical, paid parental leave, and benefits exchange model.
• Hybrid working possible within the Netherlands.
• Home‑working allowance (day and internet allowance) and laptop provision.

Diversity and inclusion are core values of Leiden University. We are committed to becoming an inclusive community that enables all students and staff to feel valued and respected and to develop their full potential. Diversity in experiences and perspectives enriches our teaching and strengthens our research. High‑quality teaching and research are inclusive.

For full consideration, please apply no later than June 29, 2026. The selection procedure will take place in June/July 2026, and selected candidates may be invited for an interview during this period.
