CV of prof. Grzegorz Litak

Dr Grzegorz Litak was born (1963) in Lublin, Poland. He completed his M.Sc. degree in physics at Maria Curie Skłodowska University (UMCS) in Lublin, Poland 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. After defending his Ph.D thesis he moved to Lublin University of Technology where he is presently working as a full professor. From that time 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 energy harvesting, focusing on frequency broadband effects. While working at the Lublin University of Technology, in 2014, he received the professor title in the field of technical sciences. In 2016-2018 he was also a professor at the AGH University of Science and Technology. G. Litak is an expert on nonlinear and complex phenomena. G. Litak published over 300 papers including about 250 in international journals. He actively collaborates with many researchers from various countries around the world. Presently, he is a member of the Polish Physical Society, European Physical Society, Polish Society of Theoretical and Applied Mechanics and Euromech. Prof. Litak was an organizer and invited speaker of many international conferences. He promoted 5 doctors in the field of mechanics and machine construction. He was also the contractor and manager of many national and international projects.

Present reseach

We study the impact of nonlinear effects on energy harvesting systems that obtain energy from the vibrations occurring in the external environment, originating from both natural processes and those caused by human activity. We explore small energy production devices utilizing phenomena of piezoelectric, electromagnetic, and electrostatic interactions.
