I was born in 1954 in Poland the same day as Mathworks 30 years later. .. I received M.Sc. degree (applied physics) in 1985 from Warsaw University of Technology (Poland), the Ph.D. degree (spectrophotometric application of digital signal processing) - in 1988 from Warsaw University of Technology.My research interests are concentrated on software aspects of measurement, in particular on applications of mathematical modelling and digital signal processing in measurement and instrumentation.
