Ramzi Khuri received his PhD in Physics at Princeton University in 1991. He spent the past seven years as a researcher in theoretical physics. During (1991-93), he was a postdoctoral fellow at Texas A&M University. Another two years (1993-94 and 1995-96) were spent at CERN in Geneva, the leading high senergy physics research institute in the world, on a John Stuart Bell Scholarship in Quantum Physics. An additional two years (1994-95 and 1996-97) were spent as a research associate at McGill University. Most recently, he held a Particle Physics and Astronomy Research Council (PPARC) Advanced Fellowship at Queen Mary and Westfield College, University of London. This last position was at the rank of Lecturer, and was intended for five years to support unhindered research.

He resigned this position August 31st, 1998 in order to assume the tenure-track position at Baruch College. In the field of string theory, he has established an international reputation, having co-authored a review, which has now become a standard reference, and having published over 50 papers, receiving over 1,000 citations. In addition, he co-organized the conference From Superstrings to Supegravity at the Etorre Majorana Centre at Erice, Italy, in December 1992.

RESEARCH

"My research career has concentrated mainly on the study of black holes, solitons and duality in string theory. The main motivation in this endeavour is an attempt to understand the nature of string theory as a theory of quantum gravity and uniting the four fundamental interactions of nature. Such a unified picture emerges via the introduction of duality maps, which relate seemingly different theories in various limits, and in which these theories appear as different phases of the same underlying theory. More recently, I have focused on the attempt to understand the quantum statistical-mechanical basis of the Bekenstein-Hawking (BH) black hole entropy formula from string theory and to a resolution of the Hawking radiation information paradox. The BH formula was derived recently for certain classes of black holes. I am currently engaged in trying to understand the physical basis for the success of this derivation and the correspondence between black holes and quantum-mechanical string states, a problem which lies at the heart of quantum gravity. In particular, fascinating new connections arise between black holes and certain soft-matter (polymer) systems."
