Energy-Efficient Circuit Design with an emphasis on:

• Subthreshold and near-threshold digital design of circuits and systems
• Library development, characterization, and selection for optimal operation.
• Approximate, significance-driven computing
• Error-resilient circuits and systems
• Efficient physical implementation methodologies for low-power
• Alternative, low-power variation tolerant logic families and digital gates
• Asynchronous circuits and components
• Feedback in digital systems
• Low-power image sensors and sensor arrays
