2000-2002 Advisory Engineer, IBM Microelectronics. Added responsibilities include funded research on neural networks and pattern recognition techniques for manufacturing and design applications, and recruiting of Ph. D. level candidates in this area.
1999-2000 Advisory Engineer, IBM Microelectronics Design automation liaison for the Chipbench VLSI tool suite on the Power4 project at IBM Austin, coordinating new development, debugging, and a complex installation process, leading a team of two engineers and programmers.
1992-1998 Advisory Engineer, IBM Austin Microprocessor Group. I developed and supported a VLSI floorplan editor with integrated automatic placement and timing for PowerPC microprocessors and support chips in IBM and Motorola. The editor is still in use, and featured novel interface techniques now showing up in mainstream web applications.
1988-1991 Staff Engineer, IBM Burlington Design Automation Group. Systems integration, user interface development; data base and algorithm development for ASIC design system used worldwide by IBM and SGS Thompson. I supervised two junior programmers and coordinated several research programmers in the construction and integration of the system.
1986-1988 Sr. Assoc. Engineer, Research Liaison with Advanced Design Automation Laboratory. I worked with the IBM Watson design automation group to define, implement, and perform systems integration for floorplanning, place and route algorithms.
1982-1986 Associate Engineer, IBM Burlington Microprocessor Design. Worked on performance analysis, floor planning and layout. I developed a course to trained newly hired programming employees in basics of VLSI design.
