Postdoctoral Researcher in Machine Learning Wildlife Audio

Postdoctoral Researcher in Machine Learning for Wildlife Audio

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

Applying is possible up to and including: 14 September 2026

We are seeking a postdoctoral researcher with a curiosity-driven record who works at the intersection of machine learning (ML) and the sounds of wildlife (“bioacoustics”). We are also happy to consider candidates in one of the two fields who can demonstrate a strong basis for working in this cross-disciplinary domain.

Specific research topics to apply to bioacoustics might include: low-footprint machine learning; acoustic signal processing enhanced by ML; human-in-the-loop/active-learning methods; representation learning; analysing sound sequences and vocal interactions; category discovery;
Perma computing.

The successful candidate will work with Dr. Dan Stowell and his research team. The position is set in the exciting, friendly, and interdisciplinary environment of the "Imaging & Bio Informatics" research group in the Leiden Institute for Advanced Computer Science (LIACS). Stowell's team also has regular close collaboration with researchers in Naturalis Biodiversity Centre, which is the Dutch national center for biodiversity information.

Among other things, Naturalis runs large-scale ML services for nature recognition, including bioacoustics algorithms developed in the team.

• Conducting rigorous research at the intersection of ML and wildlife bioacoustics;
• Actively participating in regular group and one-on-one meetings;
• Co-supervising Bachelor’s, Master’s, and PhD students;
• Presenting your research results to the scientific community at international conferences and through publications;
• Developing further collaborations in the institute and the wider research community.

The Faculty of Science is a world-class faculty where staff and students work together in a dynamic international environment. It is a faculty where personal and academic development are top priorities. Our people are committed to expand fundamental knowledge by curiosity and looking beyond the borders of their own discipline; their aim is to benefit science, and to contribute to addressing the major societal challenges of the future.

The research carried out at the Faculty of Science is very diverse, ranging from mathematics, information science, astronomy, physics, chemistry and bio-pharmaceutical sciences to biology and environmental sciences. The research activities are organised in eight institutes. These institutes offer eight bachelor’s and twelve master’s programmes. The faculty has grown strongly in recent years and now has more than 2700 staff and almost 6000 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. For more information, see (Use the "Apply for this Job" box below). and -at

The Leiden Institute of Advanced Computer Science (LIACS) is the Artificial Intelligence and Computer Science Institute in the Faculty of Science of Leiden University.
