• Hessians of the log characteristic function (“Charrelation Matrices”) as an alternative to classical High-Order Statistics
• Passive time-delay estimation for multiple signals with multiple sensors
• Passive time-delay estimation in the presence of multipath
• Spectral estimation from partial data
• Sparsity-based signal processing and system identification
• Estimation in impulsive noise
• Extended Least Squares (XLS) estimation
• Non-asymptotic performance analysis

Linear-Algebraic Tools in Signal Processing:

• Total Least Squares (TLS) and Errors-In-Variables (EIV) modeling
• Structured Total Least Squares (STLS) and related algorithms
• Algorithms for approximate joint diagonalization
