Abstract
Autonomously coordinating robotic swarms are attracting increased attention due to recent advances in making robotic platforms robust and cheap. Robotic swarms coordinate autonomously via simple control laws. Such robotic swarms are attractive for large scale applications in unstructured and dynamic environments because of their scalability and robustness to failures, such as loss of swarm members. Potential applications of robotic swarms consisting of hundreds of members are envisioned to include environmental exploration, large scale monitoring of critical infrastructure, border protection, search and rescue, environmental cleanup, agriculture and others. Human operator presence and interaction with unmanned vehicle (UV) systems, is common and necessary. The human in the loop is an important component in real applications of multi-UV systems since humans (a) are better than the swarm at many visual object and pattern recognition tasks, (b) may have out-of-band information, and (c) impart mission and goal changes to the swarm members. However, swarm human monitoring and control presents difficulties due to (1) swarm nonlinear dynamics and scale, (2) limitations imposed by the environment (e.g., limited bandwidth, noise and latency) and (3) cognitive operator limitations. Drawing from multidisciplinary research in control theory, dynamic systems, AI and Human Factors, this talk will present work that addresses the above challenges and identify open problems and opportunities.

Abstract
Discovering causal relations from data lies at the heart of most scientific research today. In apparent contradiction with the adagio "correlation does not imply causation", recent theoretical insights indicate that such causal knowledge can also be derived from purely observational data, instead of only from controlled experimentation. In the "big data" era, such observational data is abundant and being able to actually derive causal relationships from very large data sets would open up a wealth of opportunities for improving business, science, government, and healthcare.

Abstract
Computational social choice is an interdisciplinary field of study at the interface of social choice theory and computer science, promoting an exchange of ideas in both directions. On the one hand, it is concerned with the application of techniques developed in computer science, such as complexity analysis, algorithm design, or communication protocols, to the study of social choice mechanisms, such as voting procedures or fair division algorithms. On the other hand, computational social choice is concerned with importing concepts from social choice theory into computing. For instance, social welfare orderings originally developed to analyse the quality of resource allocations in human society are equally well applicable to problems in multiagent systems or network design. Computational social choice brings together ideas from computer science, artificial intelligence, logic, political science and economic theory, amongst others. Below we briefly introduce some representative problems that have been studied in the field.

Jaime Simão Sichman is an Associated Professor at University of São Paulo, from where he has obtained both his B.E. and M.E. degrees. He was one of the first students to obtain an European label to his PhD degree, developed at the Institut National Polytechnique de Grenoble (INPG), France, since part of his research was carried out at the Istituto di Psicologia del CNR (currently ISTC), Rome, Italy. More recently, he has spent an abbreviated post-doctoral period at the University of Utrecht, at the Netherlands. His main research focus is multi-agent systems, more particularly social reasoning, organizational reasoning, multi-agent-based simulation, reputation and trust, and interoperability in agent systems. He has advised/co-advised 11 MSc, 9 PhD and several undergraduate students.

Abstract
In the last years, social and organizational aspects of agency have become a major issue in MAS research. Recent applications of MAS on Web Services, Grid Computing and Ubiquitous Computing enforce the need of using these aspects in order to ensure some social order within these systems. One of the ways to assure such a social order is through the so-called multiagent organizations. Multiagent organizations are of two types: either the organization emerge from the activity of the individual agents or it is designed to facilitate and guide some specific global behavior. In the latter case, systems are characterized by the autonomy of the individual participants that however must be able to collaboratively achieve predetermined global goals, within a globally constrained environment. However, there is still a lack of a comprehensive view of the diverse concepts, models and approaches related to multiagent organizations. Moreover, most designers have doubts about how to put these concepts in practice, i.e., how to program them. This talk aims to give an answer to such questions.

Abstract
Human intelligence evolved through social interaction. Existing work on artificial agents emphasises intelligent behaviour in the context of problem solving. In this presentation, the development of social skills is argued to be pivotal in the realisation of intelligent agents. Our group studies the dynamic coupling of nonverbal behaviour in interacting human and artificial agents. The results of these studies are presented and the implications for the development of future intelligent agents are sketched.
