**Meet the editor**

Dr. Jan Valdman is an associate professor of applied mathematics at the University of South Bohemia in České Budějovice (Czech Republic) and a researcher at the Institute of Information Theory and Automation in Prague. He obtained his MSc degrees from the Mathematical Research Institute (Utrecht, the Netherlands) and the University of West Bohemia in Pilsen in 1998.

He graduated from the University of Kiel (Germany) with his PhD thesis on modeling of elastoplasticity in 2002. After spending many years at several foreign institutions (Linz, Bergen, Reykjavik, and Leipzig), he returned to Czech Republic. He worked in applied mathematics at the Technical University Ostrava in 2011. His areas of interests include computational nonlinear mechanics of solids and a posteriori error estimates for nonlinear problems. He has published several vectorized codes in MATLAB for finite element assemblies.
