I am an assistant professor of Computer Science at the Department of Computational Intelligence, Wroclaw University of Science and Technology. I have received MSc in Computer Science from the Wroclaw University of Technology, Poland in 2008 and PhD in 2012. I was a visiting scholar at Stanford University in 2013. I have authored over 60 scholarly and research articles on a variety of areas related to complex networks, focusing on the extraction and dynamics of communities within social networks, spreading processes in complex networks and the analysis of multilayer network. In 2015 I have received 3 years scholarship for the best young scientists awarded by Polish Ministry of Science and Higher Education. You can meet me at most of top conferences on social networks and social informatics e.g.: NetSci, NetSciX, IC2S2, ASONAM, SocInfo etc.
My PhD thesis topic was A Method for Group Extraction and Analysis in Multilayer Social Networks , so as I have already mentioned one of my research area is communities within complex social networks, their evolution, analysis and prediction of their future behaviour.

Testing Community Detection Algorithms in Multi–layered, Multiplex and Multiple Social Networks
This is the extention of LFR Benchmark introduced by A. Lancichinetti, S. Fortunato, F. Radicchi
in the paper Benchmark graphs for testing community detection algorithms. Community detection is one of the hottest topics in network science. While for simple (one layered) social networks there is hundreds of different algorithms for multilayer social networks there is a few. While for simple (one layered) social networks there is a number of reference dataset like karate club or football league, and few widely accepted and well tested benchmarks like GN Benchmark or LFR Benchmark for multilayer social networks there is a none. This paper propose an extension of well-known LFR Benchmark which will enable researchers to test and compare community detection algorithms in multilayer, multiplex and multiple social networks.

The continuous interest in the social network area contributes to the fast development of this field. The new possibilities of obtaining and storing data facilitate deeper analysis of the entire network, extracted social group and single individuals as well. One of the most interesting research topic is the dynamics of social group, it means analysis of Group Evolution over time. Having appropriate knowledge and methods for dynamic analysis, one may attempt to predict the future of the group and then manage it properly in order to achieve or change this predicted future according to specific needs. Such ability would be a powerful tool in the hands of human resource managers, personnel recruitment, marketing, etc.
The social Group Evolution consists of individual events and seven types of such changes have been identified in the paper: continuing, shrinking, growing, splitting, merging, dissolving and forming. To enable the analysis of Group Evolution a change indicator – inclusion measure was proposed. It has been used in a new method for exploring the evolution of social group, called Group Evolution Discovery (GED).Introduction to the GED Method the poster or/and the presentation.
