Background

Dr. Downey's expertise and research interest include low-latency machine learning, real-time model-updating, adaptive structures, and structural health monitoring. Current research is focused on: 

1. Online low-latency machine learning that considers both training and inference. To enable real-time performance this research focuses on the co-design of algorithms and heterogeneous computing hardware. These methodologies have various applications in real-time state estimation, time-series forecasting, and anomaly detection. 

2. Real-time decision-making and control for structures operating in extreme dynamic environments. Physics-informed decisions are empowered by physics-based models that are updated in real-time. Applications include hypersonic vehicles, active blast mitigation, and orbital infrastructure. 

3. Smart and adaptive structures that leverage novel sensors and structural control devices that enable a structure to learn from its environment and respond in real-time. Specific avenues of investigation include sensing skins, semi-active dampers, and active structural elements. Applications include civil infrastructure, transportation systems, and hypersonic vehicles. 

4. In situ monitoring and online validation of additively manufactured components using a variety of sensing systems. Active measurement control (spatial and temporal) enables the real-time assimilation of measurement data into physics-informed models. Applications include fused-filament fabrication (FFF), laser-based additive manufacturing (LBAF), and wire-arc additive manufacturing (WAAM).
