Daniel Lohmann (daniel@losoft.de) is Assistant Professor at the Distributed Systems and Operating Systems department at Friedrich-Alexander-University Erlangen-Nuremberg, Germany. His main research topic is the design of a highly customizable and scalable operating system product line for deeply embedded systems using static configuration and aspect-oriented techniques. Before joining Universität Erlangen he worked as a freelance trainer and consultant for NT system programming, advanced C++ programming and OOA/OOD. He is interested in upcoming programming techniques like aspect-oriented programming, generative programming and C++ meta coding and has written some nice and handy tools for Windows NT which you can download at his web site.
