Adam Wierzbicki, Ph.D.
received his Ph.D. degree from the Warsaw University of Technology and a habilitation title from the Institute of Systems Research of the Polish Academy of Sciences. He is currently employed at the Polish-Japanese Academy for Information Technology, where he has the position of Full Professor and of Vice-President. He is an expert in Social Informatics and operations research. His current research interests focus on social informatics, in particular on credibility, trust management, collective intelligence and fairness in distributed systems. Dr Wierzbicki also works on algorithms for solving multi-hard problems, which are composed of multiple hard optimization problems. He has published several papers on trust management and on applications of the theory of equity to providing fairness in open distributed systems, and is the author of a Springer book titled “Trust and Fairness in Open, Distributed Systems”. He is also interested in open collaboration, particularly using Wiki technology, and in Crowdsourcing (with an emphasis on new algorithms for evaluating and managing Crowdsourcing workers). In 2011-2015 Dr Wierzbicki headed the Reconcile project which has developed tools for the evaluation of Web content credibility. Currently, he is a Senior Researcher of the Dream
project that concerns developing IT technology for elders. Dr Wierzbicki is the Steering Committee Chair of the International Conference on Social Informatics (SocInfo
Due to his experience in research and development in Social Informatics, Dr Wierzbicki is an expert on Big Data, Web and data mining and machine learning, or more generally – Data Science. Dr Wierzbicki is also an expert on simulation and multi-agent systems, which are essential tools in the study of cause-effect relations that cannot be proven through Data Science only. His research on the design of technology that is able to better interact with communities of users can be summarized as an effort to capture the notion of Artificial Social Intelligence. This challenging goal can only be achieved through a combination of approaches used so far in AI, HCI and Social Informatics.
Dr Wierzbicki is a member of the Scientific Advisory Board of Complexica
, an Artificial Intelligence software company that helps large organisations sell more products and services, and reduce their labour costs through the use of automated analytics.

dr Leszek Bukowski
Just after my Ph.D., I started to teach at Polish-Japanese Institute of Information Technologies about social network analysis and user engaging mechanics. My main field of expertise are social networks and large graphs analysis. Currently most of my research is focused on WikiTeams project. I used to work at Polish internet company “Nextweb Media” as Main Data Scientist. I was responsible for the architecture of a system, that was processing knowledge obtained from a social graph (Facebook) of the users. I am fascinated with new media and all the possibilities they give us. I am a regular guest in Channel 4 of Polish Radio, where I am an expert in the field of ICT.
