I guess you need the Rewrite directive for what you are trying to acheive, as far as the syntax for Redirect goes
Redirect [status] URL-path URL
notice that the second argument is a URL-path which is supposed to be PATH (absolute or relative), and not a URL like you defined.
There are two walk arounds for this
1) Go into the config section of
http://csquared.stanford.edu/, and do this
Redirect permanent /
http://wilkinson.stanford.edu/csquared/2) Or use Mod_Rewrite to rewrite the URL
