Christodoulou Demetrios
Position: Faculty, ETH Zürich PhD: 1971, Dept. of Physics, Princeton University, USA Thesis: Investigations in gravitational collapse and the physics of black holes Supervisor(s): Wheeler John Archibald Biography: Demetrios Christodoulou (Greek: Δημήτριος Χριστοδούλου; born October 19, 1951[1]) is a Greek mathematician and physicist, who first became well known for his proof, together with Sergiu Klainerman, of the nonlinear stability of the Minkowski spacetime of special relativity in the framework of general relativity. Christodoulou was born in Athens and received his doctorate in physics from Princeton University in 1971 under the direction of John Archibald Wheeler.[2] After temporary positions at Caltech, CERN, and the Max Planck Institute for Physics, he became Professor of Mathematics, first at Syracuse University, then at the Courant Institute, and at Princeton University, before taking up his current position as Professor of Mathematics and Physics at the ETH Zurich in Switzerland. Achievements: In 1993, he published a book coauthored with Klainerman in which the extraordinarily difficult proof of the stability result is laid out in detail. In that year, he was named a MacArthur Fellow. In 1991, he published a paper which shows that the test masses of a gravitational wave detector suffer permanent relative displacements after the passage of a gravitational wave train, an effect which has been named "nonlinear memory effect". In the period 1987–1999 he published a series of papers on the gravitational collapse of a spherically symmetric self-gravitating scalar field and the formation of black holes and associated spacetime singularities. He also showed that, contrary to what had been expected, singularities which are not hidden in a black hole also occur.[7] However, he then showed that such "naked singularities" are unstable.[8] In 2000, Christodoulou published a book on general systems of partial differential equations deriving from a variational principle (or "action principle"). In 2007, he published a book on the formation of shock waves in 3-dimensional fluids. In 2009 he published a book where a result which complements the stability result is proved. Namely, that a sufficiently strong flux of incoming gravitational waves leads to the formation of a black hole. Awards: Christodoulou is a recipient of the Bôcher Memorial Prize, a prestigious award of the American Mathematical Society. The Bôcher Prize citation mentions his work on the spherically symmetric scalar field as well as his work on the stability of Minkowski spacetime. In 2008 he was awarded the Tomalla prize in gravitation.[10] In 2011, he and Richard S. Hamilton won the Shaw Prize in the Mathematical Sciences, "for their highly innovative works on nonlinear partial differential equations in Lorentzian and Riemannian geometry and their applications to general relativity and topology". The citation for Christodoulou mentions his work on the formation of black holes by gravitational waves as well as his earlier work on the spherically symmetric self-gravitating scalar field and his work with Klainerman on the stability of Minkowski spacetime. Christodoulou is a member of the American Academy of Arts and Sciences and of the U.S. National Academy of Sciences. In 2012 he became a fellow of the American Mathematical Society. In 2014 he was a plenary speaker at the ICM in Seoul.

Michalitsianos Andrew
Position: Researcher, NASA/GSFC PhD: 1972, Institute of Astronomy, University of Cambridge, United Kingdom Thesis: Magnetohydrodynamic processes in the active solar atmosphere Supervisor(s): Worrall Gordon - Durrant Christopher Biography: Dr. Andreas -Andy- Gerasimos Michalitsianos (Greek: Ανδρέας Γεράσιμος Μιχαλιτσιάνος) (May 22, 1947 – October 29, 1997) was a Greek-American astronomer and a NASA astrophysicist, also known and published as Andrew G. Michalitsianos. Born in Alexandria, Egypt on May 22, 1947, Andreas grew up with his mother, who spoke little English and briefly, with his father. He moved with his family to New York City in 1949 and lived in the Queens borough before going to college. Michalitsianos father, Gerasimos Andreas, was a sea captain of a Greek tanker, the SS Foundation Star (formerly SS Lampas), but the ship was caught up in a hurricane and sunk in September 1952 off the coast of Norfolk, Virginia and Michalitsianos father died of pneumonia shortly after rescue. Andreas showed an early interest in astronomy and physics from an early age, winning a science contest in 1959 and serving as president of the Junior Astronomy Club in NYC where his accomplishments included leading a South American eclipse expedition. He graduated from Newtown High School in 1965 and then earned his bachelors degree in physics from the University of Arizona at Tucson in 1969, working at the nearby Kitt Peak National Observatory as a student employee in the Space Division to help pay off his college debts. His duties at Kitt Peak included the initial tests of a remotely controlled telescope. Andreas then received a scholarship and earned his Ph.D. in astrophysics from University of Cambridge, Churchill College in 1976 while doing research on a theoretical topic in solar physics. He would later work as a junior research fellow at the California Institute of Technology and then as an astrophysicist at NASAs Goddard Space Flight Center from the 1970s until his death. Michalitsianos was involved with such projects as the Hubble Space Telescope and was the Deputy Project Manager of the Observatory Branch for Goddards highly successful International Ultraviolet Explorer, in which he won several awards for his contributions. Michalitsianos eventually went on to become Chief of the Laboratory for Astronomy and Solar Physics at the Goddard Space Flight Center in early 1997, and was renowned for his breakthrough research on symbiotic stars. His many awards included the NASA Meritorious Achievement Award. Michalitsianos died on October 29, 1997 in Baltimore, Maryland after a long struggle with a brain tumor. Until his last days he was hard at work rejuvenating the Laboratory of which he had recently taken command, and on a proposal for a spacecraft to monitor temporal changes in the ultraviolet and X-ray spectra of stars and active galaxies. He is survived by a wife, two daughters, a sister, and one son. A landbased robotic telescope on the island of Cefalonia in western Greece is named in his honor. The Andreas Gerasimos Michalitsianos telescope, located within a former Hellenic Air Force communications station, has been utilized by Greek universities and The Eudoxos Project to advance Greek secondary education in introductory astronomy and physics laboratories for high school students.
