Gonzalo Camarillo leads the Advanced Signalling Research Laboratory of Ericsson in Helsinki, Finland. He is an active participant in the IETF, where he has authored and coauthored several specifications used in the IMS. In particular, he is a co-author of themain SIP specification, RFC 3261. In addition, he co-chairs the IETF SIPPING working group, which handles the requirements from 3GPP and 3GPP2 related to SIP, and the IETF HIP (Host Identity Protocol) working group, which deals with lower-layer mobility and security. He is the Ericsson representative in the SIP Forum and is a regular speaker at different industry conferences. During his stay as a visitor researcher at Columbia University in New York, USA, he published a book entitled "SIP Demystified". Gonzalo received an M.Sc. degree in Electrical Engineering from Universidad Politecnica de Madrid, Spain, and another M.Sc. degree (also in Electrical Engineering) from the Royal Institute of Technology in Stockholm, Sweden. He is currently continuing his studies as a Ph.D. candidate at Helsinki University of Technology, in Finland.
