Short Bio

Jörn Altmann is a Professor of Technology Management, Economics and Policy at theCollege of Engineering, Seoul National University. Prior to this, he taught computer networks at the University of California at Berkeley, worked as a Senior Scientist at Hewlett-Packard Labs, and has been a postdoc at EECS and ICSI of UC Berkeley. During that time he worked on international research projects about pricing of network services. Dr. Altmann received his B.Sc. degree, his M.Sc. degree (1993), and his Ph.D. (1996) from the University of Erlangen-Nürnberg, Germany. Dr. Altmann’s current research centers on the economics of Internet services and Internet infrastructures, integrating economic models into distributed systems. In particular, he puts special focus on capacity planning, network topologies, and resource allocation. On these topics of research, he has major publications in conferences and journals, serves on editorial bodies of journals (IEEE Communications Surveys and Tutorials Journal, Electronic Commerce Research Journal), is involved in many conference program committees (Workshop on Network Science for Communication Networks,Workshop on Internet Charging and QoS Technology), and has been an invited speaker to several workshops. Currently, he is chairing the international workshop on Grid Economics and Business Models, GECON. He also served on several European, US American (National Science Foundation), and national panels for evaluating research proposals on next generation networks and emerging technologies
