Aarne Mämmelä (aarne.mammela(at)vtt.fi) was born in Vihanti, Finland in 1957. He received the degrees of Master of Science in Engineering, Licentiate in Technology, and Doctor of Technology (all with honors) from the University of Oulu, Oulu, Finland in 1983, 1988, and 1996, respectively. His doctoral thesis was on diversity (RAKE) receivers in fast fading multipath channels. From 1982 to 1993 he was with the Telecommunication Laboratory at the University of Oulu and carried out research on adaptive algorithms in spread-spectrum systems in wireless communications systems. From 1987 he gave several undergraduate and postgraduate courses as a part-time teacher, acting associate professor, or acting professor in different areas of the physical layer in wireless communications. He visited the University of Kaiserslautern in Germany in 1990-1991 as a visiting research scientist.He joined the VTT Technical Research Centre of Finland in Oulu, Finland in 1993. Since 1996 he has been a research professor of digital signal processing in wireless communications and in 2001 he received a tenure position. He visited the University of Canterbury in New Zealand in 1996-1997 as a postdoctoral research scientist. Since 2000 he has also been an adjunct professor at the Helsinki University of Technology and since 2004 an adjunct professor at the University of Oulu. Since 2001 he has regularly given a major part of the lectures in a postgraduate course on research methodology at the University of Oulu and since 2004 at the Helsinki University of Technology. He has given the lectures once also at the University of Modena in Italy. Since 2006 he has been the person in charge for the course at the University of Oulu and the course has been offered for the whole Faculty of Technology. During the last years about 50-60 students have annually attended the course. He is especially interested in research methods in engineering, philosophy and history of science and engineering, systems analysis and engineering, and adaptive estimation and synchronization problems.
