Department for Computer Simulations of Many-Particle Systems

By Guest - Posted on 15 March 2010

Department for Computer Simulations of Many-Particle SystemsThe Department was set up in 2007 on the basis of the Department for theory of metals and alloys, headed during 1990-2004 by Prof. Z.O.Gurskii. Since 2007 during 2021 the Department has been headed by Prof. T.Bryk. Since 2021 the head of Dept. is Prof. J.Ilnytskyi. Today the staff of Department consists of 15 permanent researchers (A.Baumketner, T.Bryk, T.Demchuk, A.Duviryak, K.Haydukivska, Y.Humenyuk, V.Ignatyuk, J.Ilnytskyi, O.Kalyuzhnyi, I.Mryglod, O.Patsahan, T.Verkholyak,Yu.Yaremko, D.Yaremchuk), 1 engineer (O.Farenyuk) and 2 PhD students (M.Kopcha, I-M.Ilenkov ).
