Recent work

Below are listed my most recent research publications (basically, since leaving my position at Bell Laboratories in 1997) in reverse chronological order.  As a guiding principle, my colleagues and I always endeavor to publish on subjects impacting important current research, unresolved or forgotten issues, and novel concepts.
