My publications and citations to them can be found at Google Scholar and Microsoft Academic Search (which however does not index citations to my pre-2001 particle physics publications properly). My field until 2001 was particle physics after which I changed to computer science; my physics publications can be found at the SLAC INSPIRE database.
