Are you interested in working at the Scientific Computing, Theory and Data division at the PSI?

We invite you to join us at the Paul Scherrer Institute, one of Europe's premier multidisciplinary research centres. Since its establishment in 1988, PSI has been dedicated to advancing scientific discovery across various fields. The Scientific Computing, Theory and Data (CSD) division at PSI serves as the core of computational science and data analysis at our institute, playing an important role in supporting research across all scientific disciplines.

CSD Christmas

Our Christmas party was a truly unforgettable moment that brought us all a great deal of joy. The festively decorated room was bathed in warm light and the Christmas atmosphere was palpable from the very beginning. The scent of pine branches and mandarins was in the air and contributed to the cozy atmosphere.
