Welcome !

I work at the Wroclaw University of Science and Technology, Faculty of Electrical Engineering in a beautiful city of Wroclaw, Poland. My scientific and research interests include advanced signal processing techniques applied to power systems control and analysis. Further, I teach Digital Signal Processing, Signal Theory, Principles of Electrical Engineering, Industrial Ecology, Electromegnetic Compatibility.

My primary workplace is the Department of Electrical Engineering Fundamentals (K38W05D02)


Research

My research focuses on signal processing methods with emphasis on spectrum estimation and statistics applied to power systems analysis. Recently, I started research in the area of power quality and wind power stations.
All my publications are available here:here.
