Your responsibilities

Research associates will be expected primarily to teach and conduct research. The research associate will also have the opportunity to pursue further academic qualifications, in particular a doctoral dissertation. At least one-third of set working hours will be made available for the research associate’s own academic work.

Foundation models are multi-dataset multi-task machine learning models that after pre-training can be fine-tuned to previously unseen problems. Benefitting from many examples seen in the training phase, they achieve very good performance with comparatively few new examples for a given task. Since the publication of “OmniJet Alpha - the first cross-task foundation model for particle physics” in 2024, our group has been active in developing, studying, and scaling such models.

The successful candidate will join our efforts to further develop foundation models for the application in particle physics. They will also work on evaluating their performance on data recorded by the CMS experiment.

Our group consists of more than 60 members and is deeply involved in everything from machine learning over detector R&D as well as calibration and data analysis of the CMS experiment. Interested candidates will be offered the opportunity of own research, advanced training and development of teaching skills in a stimulating scientific environment.

A close collaboration exists with other research groups in experimental and theoretical physics of the University and of DESY located on the same campus. Our group is part of the Cluster of Excellence “Quantum Universe” which performs research to understand mass and gravity at the interface between quantum physics and cosmology. The research team includes leading scientists from mathematics, particle physics, astrophysics, and cosmology at the University of Hamburg and DESY. Beyond Hamburg, we closely collaborate with other nationally and internationally leading groups on the development of AI techniques for fundamental physics, for example via the BMBF funded consortium SciFM for foundation models.

The position provides for 2.5 teaching hours per week.

Your profile

A university degree in a relevant field.

Excellent English communication skills are required.

Excellent candidates will have prior knowledge of high energy physics as well as practical experience in deep learning methods. Candidates with experience in analyzing proton-proton collision data or with developing transformer-based architectures or related ML techniques for particle physics are preferred.

Successful candidates are expected to pursue a PhD in Physics at the University of Hamburg. The regular duration of a PhD at the Department of Physics is three years.
