Welcome to STREAM

Spatio-Temporal Research for Environmental Analysis and Modelling (STREAM) is a UNSW Sydney-based research group advancing the statistical and computational methodology needed to understand, monitor, and predict complex environmental phenomena. We develop spatio-temporal statistical models that capture dependence across space and time while remaining scalable for modern, high-dimensional datasets. By combining statistical theory, numerical methods, machine learning, and scientific computing, we deliver robust inferential and predictive tools for environmental systems characterised by uncertainty, heterogeneity, and dynamic behaviour.

Our work includes scalable frameworks such as low-rank and multi-resolution representations, state-space models, and Bayesian hierarchical approaches. These methods support the analysis of massive datasets from satellite remote sensing and large sensor networks. We emphasise uncertainty quantification so predictions and forecasts can be used for risk assessment and decision-making. Our applications areas include air quality, climate dynamics, and oceanic processes, where we integrate knowledge through data assimilation and model–data fusion.

We focus on principled Bayesian inference, neural-network methods, and reproducible open-source workflows. Through collaboration with environmental scientists, government agencies, and industry, we aim to translate methodology into practical tools for environmental management and policy.
