Jorge Lobo is an ICREA Research Professor at the Department of Information and Communication Technologies at Universitat Pompeu Fabra (UPF) and a Research Staff Member at IBM T. J. Watson Research Center, New York (currently on leave).

He received his Ph.D. in Computer Science from the University of Maryland at College Park (1990), and a M.S. and a B.E. from Simon Bolivar University in Venezuela. Prior to his position at IBM Research, he was principal architect at Teltier Technologies, a startup company in the wireless telecommunication space acquired by Dynamicsoft, now part of Cisco Systems. Before joining Teltier, he was Technical Staff Member in the Network Computing Department at Bell Labs and a faculty member in the Department of Computer science at the University of Illinois in Chicago.

His research interest crosses several areas in computers science: AI, Network and System Management, Security and Privacy. For more than a decade he has been working in understanding the role of policy, norms and regulations in computer systems and networks. Policies are pervasive parts of both technical and social systems. Computer systems and networks have policies that govern system configuration, workload management, service provisioning, storage, and access control for the integrity and confidentiality of data and resources. Dr. Lobo has studied languages and system models using mathematical logic to describe, analyze and enforce policies. At Bell Labs he did pioneering work in policy-based network management. He developed the language PDL, designed to implement application-independent policy servers, whose semantics is based on formal descriptions of action theories and automata. A PDL management system was part of the first Lucent softswitch telecommunication network. The main intellectual property of Teltier was a policy server he designed for privacy and availability management of Presence Servers, a technology that is now part of Cisco Systems. In IBM, he has worked in policy language independent analysis techniques, which have been implemented to analyze PMAC policies, IBM's Policy Management Infrastructure for Autonomic Computing, and XACML policies, a well-know XML-based standard for the specification of access control policies. A PMAC dialect is used in IBM configuration management products for Storage Area Networks and the analysis tool in the Tivoli event correlation system IMPACT. His work on role mining algorithms has been implemented and is part of IBM Identity Management Products.

Jorge is an ACM Distinguished Scientist and cofounder and member of the steering committee of the IEEE International Symposium on Policies for Distributed Systems and Networks series. He has published two books, over 80 refereed articles in scientific journal and conference proceedings, and holds 7 patents in policy technologies.
