Nature provides a very valuable source of inspiration for computer science. We are adopting algorithms (e.g. evolutionary) and principles from biology and nature (e.g. bee hive) to achieve better results in various computational problems. Artificial neural networks model brain structures and neural networks of living beings, providing excellent results in classification, prediction and regression tasks. As a part of data mining, we also focus on text mining and knowledge discovery from text-based resources, including topics such as opinion mining.

His research interests range from information interactions of people on the Web as manifested by information recommendation or spreading within social networks, to social insect inspired computing and to modelling of software artifacts.
Aims her research to human interactions on the Web with special emphasis on user modelling and personalization, context awareness, collaborations and usability. This includes research of methods for automated analysis and modelling user feedback, and its evaluation by (multi/group) user studies employing eye trackers.
