Dr. Dan Forsberg received his M.Sc. degree in Computer Science (software engineering and telecommunications software) from the Helsinki University of Technology, Finland, in 2000 and his Ph.D on 2010 from Aalto University, Computer Science department (communications security). During his master's studies he was a core member and developer of The Dynamics - HUT Mobile IP software. He worked in Nokia Research Center in Helsinki from 2000 to 2009. In Nokia Dan was involved in and led many research projects focused on mobility and security in TCP/IP stack for future mobile devices. He was active in IETF and authored some Internet-Drafts and one RFC in the area of user to network interfaces (EAP, AAA, PANA). In recent years, the main focus of his work was on the SAE/LTE security standardization in the 3GPP security group (SA3). Dan led the SAE/LTE security standardization work in Nokia. He was also nominated as one of the Nokia top inventors in 2007-2008.

Dan started his D.Sc. (Tech), i.e., Ph.D. studies while working in Nokia and published several scientific papers in the area of "Improving and Distributing Key Management for Mobile Networks". He joined Helsinki University of Technology in 2009 for finalizing his Ph.D studies. Dan is also a skilled software engineer, a Unix and network administration expert for many years. He started extensively using Linux 1995 when he started graduate studies.
