**Meet the editors**

Jan Awrejcewicz graduated from the Lodz University of Technology in 1977 (Mechanics) and from the University of Lodz in 1978 (Philosophy), Poland. He obtained PhD (Habilitation) in 1981 (1990), and became a Full Professor in 1997. He authored and co-authored 42 monographs, 2 textbooks, 275 journal papers, 340 conference papers, 35 book chapters, 13 journal special issues,

edited 5 books and 13 conference proceedings, and supervised 18 PhD theses. He served in editorial boards of 40 journals, gave 80 invited seminars at international universities, delivered 30 plenary/keynote lectures and served as a member of scientific committees to 120 conferences. He was a recipient of the Humboldt Research Award in 2011.

Peter Hagedorn was born in 1941 in Berlin, Germany. He graduated in mechanical engineering and earned a doctoral degree at EPUSP (Brazil). He completed his 'habilitation' at TU Karlsruhe, Germany. From 1973 to 1974 he was a visiting Research Fellow at the AA Department of Stanford University. In October 1974 he became full professor of mechanics at TU Darmstadt, Germany. Among

other universities he served as visiting professor in Rio de Janeiro (Brazil), Berkeley, Paris, Irbid (Jordan) and Christchurch (New Zealand), where he also held an Adjunct Professorship at UCC. He served as Head of Department and Vice-President to TU Darmstadt and he is active in a number of professional and editorial committees. He is an author of over 200 papers and several books on dynamics, vibrations and analytical mechanics. He presently heads the Dynamics and Vibrations Group within the Institute of Numerical Methods in Mechanical Engineering at TU Darmstadt.
