Welcome to my website. I hope you will find useful and interesting material here. I am a retired professor of radio astronomy; although I formally retired in 2014, I still work on selected scientific programmes and on the public presentation of astronomy.

After the retirement of my teacher, Professor Stanislaw Gorgolewski, I spent many years leading the Chair of Radio Astronomy, and later, after the creation of the NCU Centre for Astronomy, I served as director of its astronomical units. My work covered the design and construction of antennas, radio receivers, control systems, and digital data-processing systems, that is, the core elements of radio astronomy instrumentation.

I began with studies of solar radio activity, but my interests later moved towards observational cosmology and the study of selected quasars and AGN by means of radio interferometry, including VLBI. A great deal of my work went into launching advanced research programmes on the RT3 and RT4 radio telescopes. Among the most important instrumental results, I would include bringing Poland into VLBI and making full scientific use of RT4.

For the first time in Poland, we carried out observations of pulsars, molecular lines, AGN with a single dish and with VLBI techniques, as well as studies of Galactic background polarisation. Teaching was also an important part of my work in radio astronomy and radio astrophysics: I supervised many MSc students and seven doctoral students. In total, I spent more than six years in leading radio astronomy centres abroad, including MRAO Cambridge, Jodrell Bank Observatory, MPIfR Bonn, ASTRON, Onsala, Caltech, MIT Haystack, and ESO in Chile.

After moving to full retirement, I turned mainly to public outreach and to bringing earlier projects to completion, including the 43 MHz survey. I have also spent much time on amateur radio telescopes, optimising photographic equipment, improving equatorial mounts, and amateur spectroscopic observations.
