His areas of expertise and research interests included Observational Astrophysics and in particular the Sun, Diffuse Nebulae, SN remnants, Reduction and Analysis of Observations from the ground and space, & Photometric and Spectroscopic Observations of Variable Stars like CVs, Eclipsing Binaries, Symbiotics. On these subjects he has published many scientific papers as well as 5 Monographs and a large number of popular articles in Greek. He was also interested in the History of the Astronomy and has written 8 Popular Books in Astronomy. He has been permanent fellow in two Popular Scientific Journals, of the encyclopaedia YDRIA, and he presents all important observational events during the year in the Journal Uranus, published by the Astronomical and Space Society, Volos.
