Professor Emeritus, Aristotle University of Thessaloniki, Greece
(since 1996). He was born in Chania, Crete, Greece on the
5th of March, 1948. He received his B.Sc. in Physics from
the University of Athens, Greece (1971), his M.Sc. in Radio
Astronomy from the Victoria University of Manchester, U.K.
(1973) and his Ph.D. in the same field from the same
University (1975). He worked in numerous Institutes and
Universities: at the Max-Planck Institut für
Radioastronomie, Bonn, Germany (07/1975-12/1976,
02/1979–04/1979, 09/1982–04/1984 Alexander von
Humboldt scholarship, 05/1984–08/1985 and 09/1991-
07/1992 on sabbatical from the Aristotle University of Thessaloniki), at the Universität Hamburg, Germany (02/1978–01/1979) and at the University of California, San Diego, U.S.A. (09/1979–06/1982). He was elected and served as Associate Professor, Aristotle University of Thessaloniki, Greece (07/1985 –05/1996). He has served as Director of the Section of Astrophysics, Astronomy and Mechanics, Department of Physics, University of Thessaloniki (1989-1990, 2001-2002, 2008- 2009), member of the Council of the Department of Physics, Aristotle University and Chairman or member in several Committees at the same University. He is a founding member of the Hellenic Astronomical Society (Hel.A.S.) where he has served as Secretary (1994-1998) and as President (1998-2002). He has served as Member (1986-1990) and as Chairman (2001-2005) of the Greek National Committee for Astronomy. Since 1992 he has served as an Expert Evaluator in European and National Programme Committees and as Referee in International Journals (since 1988), while he has served as a Member of the Time Allocation Committee of the 100m radio telescope of the MPIfR, Bonn, Germany at Effelsberg (1993-1997). His scientific interests include Neutron Stars (Pulsars), Neutral Hydrogen modeling in nearby galaxies, the Centre of our Galaxy, Flare Stars, Lunar Transient Phenomena and Archaeoastronomy. He has published more that 60 scientific papers in refereed journals, and more than 60 papers in conference proceedings and special volumes as well as three University-level Textbooks. He has also represented Greece in large European networks (OPTICON, ILIAS, CRAF, etc) and in December 2005, the highest EU prize Descartes was awarded to the Neutron Stars research network, “PULSE”, in which he is a one of the founding members. He is member of the Royal Astronomical Society (RAS), of the International Astronomical Union (IAU), of the European Astronomical Society (E.A.S., Founding Member) and of the Hellenic Physical Society.
Astrophysicist, NASA, Goddard Space Flight Center. He obtained his BA from the Franklin & Marshall College, Lancaster, PA, (1955), his Master of Science (1964) and the Ph.D. in Physics (1966), both from the University of Maryland, College Park, MD. He has spent most of his active career in X-ray astrophysics with emphasis in the development of space-borne instrumentation. He has pioneered two types of instruments which have since been used extensively in the field: the large area multiwire gas proportional counter and lightweight conical
foil X-ray mirrors. He has been principal investigator in
several satellite missions, including NASAs Astro-1
mission, flown on the Space Shuttle in December
1990, and the US/Japan collaborative spectroscopy
missions ASCA and Astro-E (the latter in preparation).
His scientific interests include Fe K lines in the spectra
of clusters of galaxies, spectra of AGN and the search
with ASCA for hard, AGN-like nuclear sources in
nearby spiral galaxies. He has been at his present
position in the X-ray astrophysics Branch at Goddard
since joining Dr. Elihu Boldt, the founder of the group in the late 1960s. The Joseph Weber Award for 2009 was conferred on him in late January in recognition of his innovative contributions to X-ray detector and telescope designs that have enabled decades of scientific advances in high energy astrophysics.
