Theoretical Physics (1997)
He was born in Athens. He studied Physics at the University of Athens and he graduated in 1971. He continued his studies at the University of Sussex in England, where he got his Ph.D. in 1973, in High Energy Physics. He has been a Research Fellow at the Center of European Nuclear Research (CERN) in Geneva, Switzerland and for many years he has been a staff member. He has also been a Research Fellow in Ecole Normale Superieure, in Paris, France and in Harvard University, Cambridge, USA. In 1989, he was elected professor at the Department of Physics, at Texas A&M University where since 1992 he is a Distinguished Professor of Physics and since 2002 he holds the Mitchell/Heep Chair in High Energy Physics. He is also Head of the Astroparticle Physics Group in Houston Advanced Research Center (HARC), in Houston, Texas, USA, where he is in charge of a research department of the World Laboratory, which is based in Switzerland. In 1997 he was appointed regular member of the Academy of Athens and in 2015 he was elected president for one year. From 2005 to 2009 he was the chairman of the Greek National Council for Research and Technology. He has served as the National representative of Greece to the European Laboratory for Particle Physics (CERN) from 2005 to 2010 and again from 2013 until 2015. He was also the National representative of Greece to the European Space Agency (ESA) from 2005 to 2006.
He has made several contributions to particle physics and cosmology. He works in string unified theories, fundamentals of quantum theory, astroparticle physics and quantum-inspired models of brain function.
He has written over 680 original papers, all published in peer-reviewed journals, with high impact factor, including 15 books. He has over 46.612 citations (h_index=105), placing him as the fourth (4th) most cited High Energy Physicist of all time according to the 2001 and 2004 census. Since 1988 he is fellow of the American Physical Society and since 1992 a member of the Italian Physical Society. In 1996, he was awarded the Commander of the Order of Honour of the Greek State and in 2005, celebration year of the 100th anniversary of the Einstein’s Relativity Theory, he received for the 2nd time (first time was in 1999) the 1st place award from the Gravity Research Foundation (Massachusetts, U.S.A.). In 2006 he received the “Onassis International Prize” and in 2009 the “Enrico Fermi” Prize.
