Key research themes
1. How can artificial noise be effectively utilized to enhance physical layer security in wireless communication systems?
This research theme investigates the role of artificially generated noise—such as jamming signals or artificial interference—in improving the secrecy and confidentiality of wireless communications at the physical layer. The focus lies on quantifying and optimizing secrecy performance metrics like secrecy outage probability and ergodic secrecy rate in scenarios where legitimate transmissions are subject to eavesdropping. Key challenges include designing noise that disrupts eavesdroppers without significantly impairing legitimate receivers, optimal power allocation between information signals and artificial noise, and evaluating impacts in advanced network architectures including RIS-aided, multi-hop, and NOMA-enabled systems.
2. What are the methodological innovations for generating, designing, and applying artificial noise and reverberation for audio and signal processing?
This theme addresses the computational and algorithmic development of artificial noise generation and reverberation modeling, particularly for applications in audio signal processing and noise mitigation. It encompasses innovative techniques such as genetic algorithms for synthesizing room impulse responses, psychoacoustically motivated designs for active noise control (ANC) that factor in human hearing perception, and optimization frameworks to create energy-efficient noise for protecting cryptographic devices. The focus is on generating artificial noise or reverberation that meets specific acoustic or security performance criteria while optimizing resource use and system robustness.
3. How does artificial noise and anthropogenic noise influence biological systems and human experience?
This research area explores the effects and perception of artificial and environmental noise on living organisms and human auditory processes. It spans behavioral impacts of anthropogenic noise across sensory modalities, psychoacoustic phenomena related to auditory illusions, and the philosophical contemplation of noise as a human experience. The focus includes behavioral experiments revealing cross-modal noise effects in animals, psychophysical characterizations of complex sound perception revealing auditory system nonlinearities, and the cultural and phenomenological dimensions of noise's ubiquity and meaning.
