1997-1999: Research Engineer, University of Texas at Austin Center for Electromechanics

• Program Manager for a National Science Foundation I/UCRC pilot project, developed simulationbased design tools for electric vehicle traction motors
• Developed advanced control and system identification algorithms for an electromechanical active suspension, implemented on a military HMMWV

1996-1997: Process Controls Consultant, Austin TX

• Designed and implemented a PLC-based control system to regulate feedwater recirculation flow on a 350 MW fossil-fueled power plant for LCRA, Austin TX
• Developed and intelligent software tools to predict and control chemical variations in a critical manufacturing process for Engelhard Corp, Attapulgus, GA

1991-1996: Graduate Research Assistant, University of Texas at Austin

• Designed an intelligent, robust controller using a novel type of artificial neural network, the 2-Sigma network, which “learned” the bounds of model uncertainties
• Implemented this controller on an industrial machine lathe to control cutting forces

1988-1991: Senior Engineer, Westvaco's Covington Research Center

• Designed an Acoustic Leak Detection System (ALDS) to detect hazardous steam leaks in black liquor recovery boilers
• Supervised the assembly, installation, testing, and operator training for eight ALDS installations in the United States and Brazil
