Welcome to PSI, the largest research institute for natural and engineering sciences in Switzerland.
Recent highlights from our research
New standards in nuclear physics
With unprecedented precision: PSI researchers measure the nuclear radius of muonic helium-3 and put the theories of atomic physics to the test.
With pad, pencil, and algorithms
Physicist Dominik Sidler is developing fundamental theories for previously inexplicable phenomena.
Prestigious funding for research at PSI
Concrete, chemical catalysis and the search for new physics – three PSI researchers have each received a grant from the Swiss National Science Foundation for these areas of research.
