Bedir Tekinerdoğan holds an MSc and a PhD degree in Computer Science from the University of Twente, The Netherlands. Currently, he is an assistant professor at University of Twente where he works on the project Aspect-Oriented Software Architecture Design which is carried out with IBM Research, The Netherlands. His current research is basically on aspect-oriented software architecture design, multidimensional separation of concerns using design space modeling and aspect-oriented domain analysis. He served on the program committee and organising committee for AOSD 2002 and was an organiser of the early aspects workshop at AOSD 2002 and AOSD 2003. He was also an organizer of several workshops at ECOOP on the topics of aspect-oriented programming, automating software development methods, and adaptability in object-oriented software development. From 1994 on, he has been teaching on the topics of aspect-oriented software development, software architecture design, object-oriented analysis and design, and object-oriented software design patterns.

Ana Moreira is an assistant professor at the Department of Informatics at the Universidade Nova Lisboa, Portugal. She holds a PhD in Computer Science in the area of formal methods and object technology. Her main research areas are object technology, requirements engineering, and formal description techniques. Currently she is interested in investigating how coordination technologies can be used to support agile software evolution and also how aspect-orientation can be used during the early phases of the software development process. She has been a member of the ECOOP and UML Program Committees for several years and is a member of the pUML (precise UML) steering committee. She is the conference chair for UML 2004 and was workshop chair for ECOOP'99 and UML'2003, and workshop co-chair for ECOOP' 2002. She co-organised several workshops for ECOOP, OOPSLA, UML and ETAPS and was an organiser of the "early aspects workshop" at AOSD 2002 and AOSD 2003.
