Dr. Jiri Cizek

Following his early contributions to spherical diffusion and reaction kinetic problems of theoretical polarography, he devoted himself entirely to the application of quantum mechanics to atomic and molecular electronic structure. He made pioneering contributions to the many-electron correlation problem by developing the necessary formalism and deriving the explicit equations for the so-called coupled cluster approach which is presently widely exploited by many researchers. During the last decade he was very influential in the introduction of algebraic methods and large order perturbation theory into quantum chemistry.
All his scientific endeavours greatly contributed to bridging the gap between applied mathematics and quantum chemistry.
