Research field

Our Unit works in computational neuroscience. We study how computations performed by circuits in the brain produce neural phenomena and cognitive functions. The Unit is particularly interested in the hippocampal region and its role in memory, spatial representation, and neurological diseases. We employ a broad range of theoretical techniques, from mathematical analysis to machine learning, and we work closely with experimental data. Please visit for more information.

Job title and description

Job title

Postdoctoral Researcher or Research Scientist, 1 position

Job description

The successful candidate will work towards understanding seizures in the hippocampus by training neural networks, performing mathematical derivations, and/or analyzing experimental data. The ideal candidate will use the Unit’s GPU server to model epileptic phenomena in recurrent neural networks trained to perform different tasks. The Unit supports the scientific curiosity of its members and would encourage the concurrent development of independent research topics and/or collaborations.


We seek outstanding researchers with a strong theoretical/computational background and an avid interest in neuroscience. The candidate should possess a doctoral degree in computer science, physics, engineering, neuroscience, psychology, mathematics, statistics, or a related field. The ideal candidate has broad experience in neural network design, training, and testing. Candidates from underrepresented groups in science are vigorously encouraged to apply.
