I am a Distinguished Member of Technical Staff at Bell Laboratories, Lucent Technologies, Inc., Alcatel-Lucent, Nokia Networks.

I also hold joint appointments as an adjunct faculty in the computer science department at the Illinois Institute of Technology in Chicago, and as a Research Fellow at the Interdiscplinary Center for Security and Trust at the University of Luxembourg, Luxembourg.

Since 1998, I have been working on multimedia signaling protocols, especially Session Initiation Protocol (SIP). The bulk of my work on SIP has been productized and powers VoLTE (Voice over LTE) in global service provider networks. I have also worked in peer-to-peer systems, especially to allow a more optimized selection of peers to deliver content (see ALTO below). More recently, I have been involved in machine learning and applying it to SIP protocol to prevent mimicry attacks. My current work focuses on massively scalable data analytics architectures and algorithms for streaming analytics as epitomized by emerging networks like 5G.

I am active in the Internet Engineering Task Force (or IETF), where I have I have produced 18 IETF RFCs and have co-chaired 2 working groups: ALTO and CUSS. In Application Layer Traffic Optimization (or ALTO) working group, we are designing a protocol that will provide p2p applications with information to perform better-than-random initial peer selection. In Call Control UUI Services for SIP (or CUSS) working group, we are defining an extension to SIP for transporting user-to-user information for applications using SIP to establish multimedia sessions.

The ALTO working group attracted fair amount of press when it was in the process of being formed. When we met as a BoF session in the Dublin IETF (Aug, 2008), Heise Online printed this. Their coverage of our Minneapolis meeting resulted in this. Things have quieted down more recently as the novelty of the working group has worn off and we have produced a protocol. The CUSS working group did not elicit comparable media frenzy, alas. It did conclude successfully, though, after meeting all its deliverables.
