Today I talk with prof. Mikko Siponen. He is a Professor of Information Systems at the University of Jyväskylä. His research interests include IS security, IS development, computer ethics, and philosophical aspects of IS. He has published extensively in top IS journals like MISQ, ISR, JAIS, EJIS and others. He has been guest SE and AE for the MISQ and held editorial positions at JAIS, EJIS, I&M, and CAIS.  Prof. Siponen has unique mix of education (Ph.D. in Philosophy from the University of Joensuu, Finland, and a Ph.D. in Information Systems From the University of Oulu, Finland), proven track of publications covering IS and Philosophy in IS. He has supervised 25 Ph.D. and more than 100 Master's theses to the completion. It is based on this unique background and experience that he shares with us his view on philosophy in IS. He is so far the only Information Systems scholar invited to the Finnish Academy of Science and Letters. Today with prof. Siponen we talk how you engage in philosophy by giving very practical suggestions, how you should think about philosophy, how philosophy can help you in your argumentation process and much more. It is my pleasure to bring you prof. Siponen.
