Prof. Grzegorz Litak was born 12.04.1963 in Lublin. He completed his M.Sc. degree in physics at Skłodowska (UMCS) in Lublin, in 1988. Later, working on the effect of disorder on correlated and exotic superconductors, he received his Ph.D (1994) and D.Sc (2002) degrees from the same University. His theoretical studies included multi-orbital superconductors, triplet superconductors including the effect of spin-orbit coupling on a superconducting state. After defending his Ph.D thesis he moved to in Lublin where he is presently working as a full professor. From 1994 he also started his research on nonlinear dynamics. He focused on bifurcation theory, chaotic dynamics and nonlinear time series analysis. Recently, he was also involved in research on mechanical and thermal energy harvesting, focusing on frequency broadband effects. G. Litak published over 250 papers including about 180 in the international journals.
