Jan Zarzycki (Polish: [jan zaˈʐɨt͡skʲi], born 29 December 1949)) is a Polish applied mathematician and engineer. He is a professor of engineering.

Biography

[edit]

He was born on 29 December 1949.[2][3] He is the son of medicine professor Jan Piotr Zarzycki and Janina nee Furgałła.[2]In 1967, he graduated (Matura) from the II High School named after the Piasts of Silesia in Wrocław. He is graduate of Wroclaw University of Technology (major: electronics, class of 1972). He was a participant of the Experimental Study of Fundamental Problems of Technology and the Doctoral Studies at the Institute of Technical Cybernetics of the Faculty of Electronics of Wrocław University of Technology.[4] In 1975 he obtained a Doctor of Science degree based on dissertation thesis entitled ‘'The relationship between the Volterra series-defined characteristics of an electroacoustic path and the resulting distortion of audio signals in it’', and then in 1986 a further dr hab. ("doktor habilitowany") degree (see: Habilitation) at the Faculty of Electronics of the Wrocław University of Technology.

The supervisor for the dissertation was Bronislaw Rogala.[1] His research subject were signal processing issues. From this subject he obtained results, which he presented in his doctoral dissertation. He was elevated to the degree of Professor of Technical Sciences in 2004 through a formal nomination by the President of the Republic of Poland. The title of Professor of Technical Sciences was conferred on him in 2004[5][6].

Contributions

[edit]

Jan Zarzycki’s scientific work has focused on advancing mathematical and computational methods in signal processing and stochastic modeling. He is particularly known for his research on Schur-type parametrization of higher-order stochastic processes and the development of orthogonal lattice-based representations of nonlinear signals, which extend the applicability of classical Schur algorithms to broader classes of stochastic systems.[7][8]

He has also contributed to the field of acoustic signal analysis, including the development of adaptive Schur-like methods for the detection and classification of impulsive "click-type" signals, such as those produced by marine mammals, even in low signal-to-noise conditions.[8] These approaches have been applied in both engineering and biological contexts, demonstrating the versatility of parametric signal representations.[9]

Jan Zarzycki was the advisor of 6 PhD theses.[10] He is the author of several dozen scientific and research papers containing his original results, two monographs and two academic textbooks.[11][12]

Jan Zarzycki has conducted numerous research projects, both national and international, and is a co-author of a patent.[13]

Awards

[edit]

In January 2017, Prof. Jan Zarzycki was awarded the medal for the 70th anniversary of the Wrocław branch of the Association of Polish Electricians (SEP).[14]
