Research Profile
My research develops data-driven and probabilistic methods for understanding dependence, causality, and uncertainty in signals and complex dynamical systems. A central theme is the use of information-theoretic quantities—especially transfer entropy and mutual information—to move beyond correlation and identify directional relationships in speech, neural, climate, remote-sensing, and industrial data.
Research Themes
Core Areas
Speech & Audio Intelligence
Audio watermarking, steganalysis, speech biometrics, voice disguise detection, and secure voice technologies.
Statistical Signal Processing
Bayesian filtering, particle filtering, non-Gaussian modeling, heavy-tailed distributions, and time-varying AR processes.
Climate & Remote Sensing AI
Information-theoretic analysis of climate feedbacks, aerosol bias correction, and nonlinear Earth-system relationships.
Selected Projects
Research Across AI, Speech, Climate, and Industry
Audio Watermarking and Steganalysis
Development of advanced signal processing techniques for perceptually transparent and robust audio watermarking, including amplitude, phase, spread-spectrum, and feature-based strategies across time and frequency domains.
Climate Feedback and Information Flow
Transfer entropy and mutual information methods for identifying nonlinear cause-effect dependencies among climate variables, including applications to cloud coverage, sea surface temperature, and aerosol optical depth analysis.
Speech Biometrics and Digital Forensics
Voice biometrics, forensic anthropometry from speech, voice disguise analysis, and computer vision methods for mission-readiness evaluation.
Industrial Statistical Modeling and Experimental Design
Statistical design of experiments, process analytics, anomaly detection, industrial data analysis, and patented contributions to materials and manufacturing research.
