Dr. DARREL J. VAN BUER

PROFESSIONAL SUMMARY:

CAREER HIGHLIGHTS

HRL Laboratories (formerly Hughes Research Laboratories): March 1998 - present

• Performing research and development in the areas of satellite and wireless networking as a medium for database dissemination.

Data Integration: October 1990 - December 1997

• Designed and implemented schema translation for the InterViso Federated Data Manager which uses a combination of query transformation and interpretative techniques to provide powerful and efficient data value transformation and selection.
• Responsible for maintenance and enhancements to the InterViso query optimizer.
• Responsible for development of interfaces between InterViso and most relational DBMS and gateway products including DB2, Cross Access, EDA/SQL, Oracle, Sybase, and ODBC.
• Designed and built a program to relationally normalize IDMS and IMS data descriptions.
• Installation and support of Unix operating system.

SDC/Unisys: 1978 - 1990

• Member of a group which implemented a semiautomatic theorem prover in Prolog and Common Lisp.
• Designed database caching strategies for expert systems to efficiently access external databases.
• Participated in the selection and modification of an Ada compiler front end to pre-process verification assertions in Ada programs.
• Implemented the Flexible Deductive Engine, a system for logic programming and database augmentation with access to external relational databases. He developed the networking software and DBMS interfaces as well as a flexible new system combining logic programming and deductive data management.
• Was responsible for implementing modifications and enhancements to the Deductively Augmented Data Management (DADM) system, an early system for logic programming and deductive data management.
• Reimplemented the low level support routines for list processing, including garbage collection, and for formatted I/O when CWIC (a list processing and compiler compiler system) was rehosted into C. Used CWIC to generate a Jovial 73 compiler.

UCLA Pharmacology Department 1976 - 1978

• Developed programs for processing and numerical analysis of experimantal data.

Iowa State University Computation Center 1974 - 1975

• System programming on MVS/MVT for360-370.
