Biographical Sketch

John Pfaltz received his Ph.D. in Computer Science at the University of Maryland in 1969. He joined the University of Virginia as an Assistant Professor of Computer Science in 1968, becoming an Associate Professor in 1970 and a Professor in 1982. He has directed nine Ph.D. theses, and is author or co-author of two books and over 40 papers. John Pfaltz retired and is still active in research as Emeritus Professor.


Pfaltz led the development of ADAMS, an Advanced Data Management System. The ADAMS system uses suffix-based notation and was designed to manage large scientific databases in a distributed memory, parallel processing environment. His current emphasis is on closure systems and their applications to computer science. These closure systems provide a formal mechanism for studying the nature of discrete systems which underlie the foundations of computer science. Closure spaces permit the definition of complete and closed functions on discrete systems, which fill the role of "continuous" functions over continuous manifolds.
