This PhD position will be hosted at the Department of Mathematical Sciences (IMF), holding broad competences in both pure and applied mathematics. The position will be part of the research centre the Norwegian Center on AI for Decision (aiD) cooperating with over 60 companies.

The research will integrate techniques of numerical analysis and structure-preserving algorithms to generative modeling in AI. It will build upon the work done at IMF and SINTEF in this field. We will consider techniques like flow matching, and use ideas from optimal transport and neural (stochastic) differential equations, invariant Kalman filtering and geometric numerical integration. The application areas will be chosen among the use cases of the aiD canter. The direction of research will be adapted to the strengths of the recruited candidate.

Are you motivated to take a step towards a doctorate and open exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

Your supervisors will be Professor Elena Celledoni (IMF) and Senior Researcher Sølve Eidnes (SINTEF).

Your immediate leader will be the Head of Department.
