HECTOR GEFFNERhectorHector Geffner is an ICREA Research Professor at the Department of Information and Communication Technologies, UPF. He obtained a BSc on  Electrical Engineering at the Universidad Simon Bolivar in Caracas, and a MSc in Systems Science and a PhD in Computer Science  at the University of California, Los Angeles (UCLA). After his PhD, he worked at the IBM T.J. Watson Research Center in NY, USA from 1989 until 1992, and at the Universidad Simon Bolivar, in Caracas, from 1992 until 2001. He also taught at Stanford University, Aachen University of Technology, Linkoping University, Universite Paul Sabatier, and the University of Edinburgh, among other places. Since 2001 he has been at the UPF in Barcelona, as an ICREA Research Professor where he heads the Artificial Intelligence (AI) group.

Hector works on planning and plan recognition in intelligent systems, developing methods for generating and recognizing autonomous behavior automatically using model-based methods. In these methods, agents are not programmed by hand, but rather derive their behavior by solving a model of the interaction between the agent, the environment, and possibly other agents. One of the main challenges in planning is computational as these models are all intractable in the worst case, and algorithms must be able to automatically recognize and exploit the structure of problems. The work involves logical and probabilistic models, domain-independent heuristics and algorithms, and computational experiments.

Hector's research is relevant to both artificial intelligence and cognitive science, as it aims to uncover general principles of rational behavior that take into account the computational constraints that are present in both natural and artificial systems. While his main interests are in AI and Cognitive Science, he is also quite interested in the Human and Social Sciences. He is currently involved in several funded research projects, basic and applied, including a Consolider Project about Simulating the Past that involves a number of archeologists; an European Project, Spacebook, for developing speech-driven, hands-free, eyes-free devices for pedestrian navigation and exploration, and a National I+D Project, about robust and scalable model-based methods for the generation of autonomous behavior.

Hector Geffner is the recipient of the 1990 ACM Dissertation Award, and is best known for the heuristic search approach to planning for which he received the 2009 and 2010 ICAPS Influential Paper Awards. He is a fellow of both the American and  the European Association for Artificial Intelligence (AAAI, ECCAI), and Associate Editor of the two top AI journals: Artificial Intelligence (AIJ), and the Journal of Artificial Intelligence Research (JAIR). He is  professionally involved in many of the top AI conferences, having served in recent years as Area Chair for  IJCAI, AAAI, ECAI, UAI, and KR, and as co-chair of ICAPS. Hector is the author of the book Default Reasoning, MIT Press, 1992, and co-editor with Rina Dechter and Joseph Halpern of the book 'Heuristics, Probability and Causality: A Tribute to Judea Pearl', College Publications, 2010. He is currently the Director of the UPF Master in Intelligent Interactive Systems.

ANDERS JONSSONAnders Jonsson is a Lecturer in Department of Information and Communication Technologies, UPF. He is a native of Stockholm, Sweden. He received his MSc in Engineering Physics from the Royal Institute of Technology in Stockholm, and his Ph.D. in computer science from the University of Massachusetts Amherst. He joined UPF in 2005 as a visiting lecturer and member of the Artificial Intelligence group.

Anders' main research interest is devising automatic techniques for solving sequential decision problems in the form of either reinforcement learning or artificial intelligence planning. In particular, his focus is finding and exploiting the structure of such problems in order to simplify their solution. This structure can take many forms, but usually manifests itself either as abstract
states, in which the same solution holds for several different situations, or abstract actions, in which actions can be grouped together in a hierarchy. He is also interested in analyzing the  computational complexity of solving different classes of sequential decision problems.

Anders also enjoys developing artificial intelligence solutions for real-world applications. During the past few years he has been involved in several research projects, both at the national and international level. He has also published several papers in prestigious international journals and serves on the programming committee of a number of international conferences.

Apart from research in artificial intelligence, Anders really enjoys programming, and for the last five years he has served as coach of the UPF programming team at the Southwestern Europe Regional Contest, part of the ACM International Collegiate Programming Contest.

Jorge Lobo is an ICREA Research Professor at the Department of Information and Communication Technologies of theUniversitatPompeuFabra. He is also Visiting Professor at the Department of Computing of Imperial College London.

He received his Ph.D. in Computer Science from the University of Maryland, College Park, and a M.Sc. and a B.E. from Simon Bolivar University, Venezuela. Before joining ICREA, he was Research Staff Member at IBM T. J. Watson Research Center. Prior to IBM, he was principal architect at TeltierTechnologies, a startup company in the wireless telecom space, Technical Staff at Bell Labs and tenured associate professor at the University of Illinois at Chicago.

For many yearsJorge has been using tools and techniques from Artificial Intelligence for tackling management issues of distributed systems and networks working towards the aim of building autonomic management systemsand networking now becoming an intrinsic part of computation is bringing with it a host of new theoretical and practical challenges.  One major challenge is handling the mobility of network clients which are connecting using many different types of channels and networks. Another challenge is handling services that are hosted in virtual environments and can themselves outlive the computers where they are hosted: virtual computers where these services temporally reside go up and down and migrate around different computers over a network. Common to these, and many other examples, is a heightened complexity of managing these systems.

Jorge has many contributions in the formalization and implementation of policy-based management systems. Policies can be found in areas such as data center configuration, traffic and workload management, service provisioning, storage, and access control. In social systems, organizations have policies and regulations covering proper conduct to protect the safety and privacy of people and for effective and appropriate use of resources. IT systems that support these social organizations need to comply with these policies. Over the years, Jorgehas collaborated with researchers working in security, networking, distributed computing and human-computer interaction, to tackle many policy issues including authoring, verification, automatic policy generation and conflict resolution, and has developed implementations to help manage many kinds of real-world distributed systems, including computer, cellular and mobile ad-hoc networks. His recent publications address problems in areas such as declarative distributed computing, software defined networks and access control in federated databases.

He has published two books and over 100 refereed articles in scientific journals and proceedings across the AI, Networking and Security fields, with papers in conferences such as AAAI, INFOCOM and CSF.  Jorge is an ACM Distinguished Scientist.
