EXPERIENCE

Research Staff Member      June 1998 - Present

Research Associate      May 1996 - May 1998

Implemented a large version of the SHRIMP system consisting of sixteen commodity PCs connected by network interfaces developed as part of my dissertation research. Currently evaluating this system and characterizing its behavior.

Dissertation Research      September 1992 - April 1996

Built the SHRIMP system, a cluster of commodity PCs that supports high-performance multiprogramming by providing protected, user-level communication. Designed and implemented a custom network interface to provide necessary support---primarily protection---for the communication mechanism, as well as efficient data transport.

Graduate Research      September 1991 - August 1992

Simulated various memory-to-processor interconnection schemes for shared-memory, multiprocessor nodes of a distributed-memory machine.

Graduate Research      October 1990 - August 1991

Conducted research into the static, fine-grain parallelization of sequential programs for a shared-memory multiprocessor.

Graduate Teaching Assistant      September 1989 - January 1990

Responsibilities included teaching laboratory portion of digital circuit design course, creating laboratory assignments, and managing two other teaching assistants.

Graduate Research Assistant      June 1989 - August 1989

Designed a logic board to interface an IBM PS/2 to a high-speed, fiber-optic network through the Micro Channel bus.

Consultant      June 1986 - August 1988

Studied the implementation feasibility and potential cost of a next-generation, portable electronic device.

Digital Design Engineer      June 1986 - August 1988

Designed a multi-processor terminal interface board for use in Multibus systems, a standard cell ASIC for video control, and a high-end windowing terminal. Designed the logic and printed circuit board layout for a video card.

Senior Design Research      September 1985 - June 1986

Participated in a joint project with the Chemistry Department to design the logic and PC board for a system to accurately measure fluid viscosities.
