My main area of research has been General Relativity. I have particular interest in the study of Quantum Field Theory on Curved Spaces and in some dynamical aspects of GR. More recently, I have studied also some topics of Statistical Mechanics, Complex Systems, and Biophysics. Almost all of my papers can be found on-line in the arXiv.org e-Print archives. You can obtain the list of my High Energy PhysicS papers from INSPIRE-HEP. Many of my works are reviewed in the Mathematical Reviews (Subscription required) of the American Mathematical Society and in the Zentralblatt für Mathematik. You can also find information about my papers and citations in my ResearcherID.org webpage available here, and in my Google Scholar profile.

Some of the numerical codes used in my papers can be found here.
