NUMA, a research section within the Department of Computer Science at KU Leuven, is seeking a postdoctoral researcher to join their team in the field of interacting particle methods for Bayesian inversion with model error. NUMA specializes in numerical analysis and applied mathematics, focusing on the development of numerical algorithms and software for large-scale scientific and engineering problems. The group is internationally recognized and offers a vibrant research environment with 12 permanent staff and around 60 PhD and postdoctoral researchers.

The successful candidate will contribute to advancing Bayesian computational methods for inverse problems, particularly those involving partial differential equations (PDEs) with high-dimensional parameters and state variables. The project aims to increase the validity of interacting particle methods for Bayesian inversion by explicitly incorporating model error into the likelihood evaluation. A key application area is the inference of parameters in phenomenological models for cardiac electrophysiology, benefiting from collaboration with the Department of Cardiovascular Imaging and Dynamics at KU Leuven.

Candidates should hold a PhD in Mathematical Engineering, Applied Mathematics, or a closely related field. Essential qualifications include a strong background in numerical methods for differential equations, simulation of stochastic processes, and/or optimization. Experience with Bayesian sampling methods and scientific software programming is highly valued, and familiarity with cardiac electrophysiological modeling is considered a plus. Excellent English proficiency and strong communication skills are required.

The position offers a high-level international research environment, opportunities for professional development, and a supportive team. Funding is secured for two years, with the possibility of a third year depending on funding and scientific progress. The salary is competitive. KU Leuven is committed to diversity, inclusion, and equal opportunity.

To apply, candidates should submit a letter of motivation, CV, copies of university diplomas and transcripts, and contact information for 1-2 references. Applications are reviewed on a rolling basis until the position is filled, with a formal deadline of February 28, 2026. For further information, contact Prof. dr. ir. Giovanni Samaey at [email protected]. Apply via the official KU Leuven jobsite.
