Researcher / Lecturer at the Department of Computer Science and Information Technology at West Pomeranian University of Technology in Szczecin, Poland.

Research interests are related to social networks, information diffusion, human-computer interaction and online marketing. Solid theoretical and practical knowledge of online marketing, compounded by experience in tracking systems and optimization techniques. Ph.D. in Computer Science from the Technical University of Szczecin. Minor field features online marketing, decision support, decisions under uncertainty and fuzzy modeling. Online experiences since 2000 and engagement in several projects related to marketing programs, ad management systems, campaigns monitoring and trafficking, online social platforms and virtual worlds.

Key lectures: Web systems and applications, Digital marketing, Online information systems, User centered design
