OBJECTIVE

A research, software engineering or teaching position in computer science. Specific areas of interest include application design and development, mathematical software, programming environments, and real world applications of computing technology.

PROFESSIONAL EXPERIENCE

[Sept 1991 - present]

Research Scientist

Purdue University Computer Sciences Department

Responsible for the design and development of Pellpack, a problem solving environment for simulating physical applications based on partial differential equations (PDEs). Pellpack is a large scale software system (1 million lines of code) with facilities for language processing, scientific computing, geometry modeling, data visualization, and parallel processing. Major contributions include

• design and implementation of methods for interfacing new PDE solvers into the system,
• management of development efforts for undergraduates, graduate students and staff who wrote code or contributed research to the system, and
• responsibility for developing an Internet-based client-server implementation of the Pellpack system, accessible via JAVA-enabled browsers.

Responsible for the design and development of a knowledge/database system for managing and analyzing performance data generated by scientific software. Created an SQL-enhanced "forms-oriented" graphical interface to POSTGRES95, and integrated an analysis system for extracting, viewing and evaluating data from the scientific database.

Responsible for the design of SoftLab, a "virtual laboratory" prototype in the area of chemical engineering . The system was implemented as a software interface to the experimental lab and to the computer simulation programs used in the engineering laboratory. The interface allows users to control both the simulation and experimental processes, and to integrate the processes by combining results and data visualization.

[Aug 1989 - Aug 1991]

Senior Systems Analyst

Pritsker Corporation

Developed the animation system for the SLAM manufacturing simulation software and designed and implemented a system for creating marketing demonstration packages.

[July 1986 - Aug 1989]

Director, Research and Development

Network Synergies, Incorporated

Responsible for the design and development of STAR, a software package for data network optimization. Designed and built the original, marketable product, and supervised the design and development of subsequent versions. Network design modules used heuristic algorithms in conjunction with carrier pricing data. Performance analysis modules used mathematical models for response and saturation analysis, queueing, and flow deviation.

[June 1982 - Aug 1984]

Manager, Analytic Methods Group

AT&T Information Systems

Responsible for the design and analysis of proposed customer data networks, including cost and performance analysis, capacity planning, and simulation of customer data flow.

[Aug 1980 - June 1982]

Manager, Applications Consulting Group

Applied Data Research

Responsible for customer consulting services for the EMPIRE financial modeling package. Major projects included a Corporate Planning and Energy Forecasting System for a major utility, and an Inventory Control System for a chemical company.
