Editing Pascal Costanza

[[File:Pascal Costanza (118221381).jpg|thumb|Pascal Costanza.]]
'''Pascal Costanza''' is a research scientist at the ExaScience Lab at [[Intel]] Belgium. He is known in the field of [[functional programming]] in [[LISP]] as well as in the [[aspect-oriented programming]] (AOP) community for contributions to this field by applying AOP through Lisp<sup>[[#Notes|1]]</sup>.  More recently, he has developed Context-oriented programming, with Robert Hirschfeld.

His past involvements include specification and implementation of the languages Gilgul and Lava, and the design and application of the JMangler framework for load-time transformation of Java class files. He has also implemented ContextL, the first programming language extension for Context-oriented Programming based on [[CLOS]], and aspect-oriented extensions for CLOS. He is furthermore the initiator and lead of Closer, an open source project that provides a compatibility layer for the CLOS MOP across multiple [[Common Lisp]] implementations. He has also co-organized numerous workshops on Unanticipated Software Evolution, Aspect-Oriented Programming, Object Technology for Ambient Intelligence, Lisp, and redefinition of computing. He has a Ph.D. degree from the [[University of Bonn]], [[Germany]].
