Iraj Saniee is Head of the Mathematics & Algorithms Research Group at Nokia Bell Labs, in Murray Hill, NJ. The Group consists of three departments focusing on Systems, Communications and Networks in Murray Hill (USA), Paris-Saclay (France) and Cambridge (United Kingdom), respectively. The departments are headed by Matthew Andrews, Carl Nuzman and Anne Bouillard.

Iraj's research interests span a spectrum of topics in applied mathematics, modeling & analysis, and optimization of communications networks and systems, with focus on the structure and architecture of networks, scalable algorithms for network problems and applications to the design tools and control mechanisms for emerging communication systems.

Prior to Bell Labs and until 1998, he was a research director in the Information Sciences Lab at Bellcore in Morristown, New Jersey.

In addition to his research in support of Nokia products and services, in the past decade Iraj has been the recipient of DARPA, AFOSR and NIST contracts and grants on such topics as control mechanisms for MANETs, large-scale geometry of networks and inference from large graphs. His current focus is on deep learning, large graph analytics and distributed self-organizing network control.
