Kamil Urbanowicz is an Associate Professor at the West Pomeranian University of Technology in Szczecin, Poland. He got his B.Sc. and M.S. degrees at the Szczecin Polytechnic University in 2004. He took his Ph.D. degree at the West Pomeranian University of Technology in 2009, in the field of fluid transients. He has been a member of the Polish Society of Theoretical and Applied Mechanics since October 2008 and a member of the Polish Academy of Science since February 2021. By himself or with coauthors, he has published 85 papers in the scientific journals and proceedings of various international and domestic scientific conferences. He is also a co-author of five patents (five others under review). His research work has been done in the field of fluid transients and related phenomena, column separation, and unsteady friction. He is a multiple participant in specialized international conferences, for example: Pressure Surges or Fluid Mechanics Conference. Nowadays, actively cooperate with experienced scientists from all over the world. He is a reviewer in around 50 top world-class scientific journals (indexed with a high impact factor). He has been awarded multiple times by the Rector of West Pomeranian University of Technology for achievements and contributions to the development of scientific research.

Arris Tijsseling is an Associate Professor at the Department of Mathematics and Computer Science, Eindhoven University of Technology, Eindhoven, The Netherlands. He completed his M.Sc. in Applied Mathematics (1986) and a Ph.D. in Civil Engineering (1993), both at Delft University of Technology, The Netherlands. Before his current role, he worked on water hammer and fluid-structure interaction in pipe systems from 1986 to 1993 at Delft Hydraulics and Delft University, and from 1993 to 1999 at the University of Dundee in Scotland. Since 1999 he has been at the Eindhoven University of Technology. His research interests include hydraulic transients, fluid-structure interaction, multi-phase flow, sloshing, dancing manhole covers, and the history of science.
