Kati came to CERN in 1991 and completed her Diploma Thesis for the Helsinki University of Technology on simulation of hadronic showers with GEANT. After a fellowship at CERN, she joined the ETHZ group in the CMS experiment and made the earliest studies on Higgs boson decaying into two photons and wrote her PhD thesis on the discovery potential of the Standard Model Higgs boson in 1998.
She joined the Helsinki Institute of Physics and has dedicated her energy to various tasks and responsibilities in CMS, ranging from physics studies to physics user support including e-learning courses for physics analysis tools. She currently coordinates the Data preservation and Open access project in the CMS experiment and has been the prime mover behind the CERN open data release. She has a particular interest in learning and teaching, and hopes to get the CMS open data in use in outreach and education.
She has taken over the responsibility of the CERN co-operation network for schools in Finland from form Riitta Rinta-Filppula, ensuring the continuity of this highly successful program in Finland.
Kati was nominated as the Finish representative to IPPOG in March 2016.
