Biographical note

Peter Moczo is a professor of physics and Chair of the Department of Astronomy, Physics of the Earth, and Meteorology at Comenius University, Bratislava. He is the main author of several monographs and extended articles on the finite-difference method (including the highly-respected Acta Physica Slovaca article which partly forms the basis of this book). Professor Moczo is a member of the Learned Society of the Slovak Academy of Sciences, and his awards include the Prize of the Slovak Academy of Sciences for Infrastructure, the Silver Medal of the Faculty of Mathematics, Physics and Informatics of Comenius University, and the Dionyz Stur Medal of the Slovak Academy of Sciences for Achievements in Natural Sciences. Along with his two co-authors, Professor Moczo is a leading member of the (informal) NuQuake research group, studying numerical modelling of seismic wave propagation and earthquake motion, at Comenius University and the Slovak Academy of Science in Bratislava. As part of this group, all three authors were major contributors to the elaboration of the finite-difference method and hybrid finite-difference/finite-element method. Jozef Kristek is an associate professor of physics at the Department of Astronomy, Physics of the Earth, and Meteorology at Comenius University, Bratislava. His research, as part of the NuQuake group, focuses on the development of numerical-modelling methods for seismic wave propagation and earthquake motion in structurally complex media. Dr Kristek has been awarded the Prize of the Slovak Academy of Sciences for Infrastructure and the Dean's Prize for Science for his work in this area. Martin Gális is a postdoctoral researcher at the King Abdullah University of Science and Technology (KAUST), Saudi Arabia. Dr Gális' research also focuses on the development of numerical-modelling methods for seismic wave propagation and earthquake motion in structurally complex media. He has also been awarded the Prize of the Slovak Academy of Sciences for Infrastructure.
