Improved Stochastic Subspace System Identification for Structural Health Monitoring
Journal of Physics: Conference Series, 2015 Structural health monitoring acquires structural information through numerous sensor measurements. Vibrational measurement data render the dynamic characteristics of structures to be extracted, in particular of the modal properties such as natural frequencies, damping, and mode shapes.

Towards Efficient Maximum Likelihood Estimation of LPV-SS Models
, 2018 How to efficiently identify multiple-input multiple-output (MIMO) linear parameter-varying (LPV) discrete-time state-space (SS) models with affine dependence on the scheduling variable still remains an open question, as identification methods proposed in

A Mixed Frequency BVAR for the Australian Economy*
Economic Record, EarlyView.A mixed frequency vector autoregression (MFVAR) model is proposed for nowcasting, forecasting and backcasting Australian macroeconomic indicators at monthly and quarterly frequencies. A novel augmented Minnesota prior for MFVAR models is also introduced.
