Sajti Szilárd is a physicist, graduated from the University of Technology and Economics, Budapest in 1999. In 2004 he joined the Nuclear Solid State Physics section of KFKI RMKI. He has been working on modelling and data evaluation of different nuclear solid state spectroscopies, including neutron reflectometry, off-specular scattering of neutrons and nuclear resonant synchtrotron radiation, conversion electron Mössbauer spectroscopy and others. Szilard's main achievement is FitSuite.
