The most impressive physical security research team in the world is probably Roger Johnston’s Vulnerability Assessment Team at Los Alamos. People outside the USA have been having some difficulty getting papers from their web pages, so I have cached their papers on one of our servers here:

Many thanks Ross, fascinating collection of material
Minor spelling correction: That would be Roger Johnston.
(fixed – thanks, Ross)
FYI:
In October 2007 Roger Johnston became the head of the Vulnerability Assessment Team (VAT) at Argonne National Laboratory (Argonne).

The VAT is also hosting the Journal of Physical Security a scholarly, peer-review journal devoted to physical security R&D.
