Research Interests

Software Engineering, especially tools and techniques for building and managing large software systems. Software Configuration Management and Version Control.

Programming Language Design and Implementation. Investigations of non-traditional structures for compilers. Compiler perfomance improvement through restructuring.

Projects

Concurrent Compiler Development Project

Design and implementation of a concurrent compiler for the Modula-2+ dialect of Modula-2.

Front End Data Base

A investigation of the compiler performance improvements that can be obtained by modifying the front end of a C compiler to use a database system for standard include files. A prototype C compiler has been built based on gcc and gdbm.
