# Tan Bui-Thanh **Domain:** Austin Research / People **Doc Type:** Research entity **Source basis:** Supplied research cluster with linked references; see the [[wiki/Austin Research Evidence Map|evidence map]] for verification scope. **Tan Bui-Thanh** is an Oden researcher whose work joins [[wiki/Inverse Problem|inverse problems]], [[wiki/Reduced-Order Modeling|model reduction]], uncertainty, and predictive computation. Oden’s 2017 account documents [[wiki/Defense Threat Reduction Agency|DTRA]] support for faster prediction of nuclear-weapon radiation effects. The problem is operational timing as well as accuracy: expensive high-fidelity calculations must be made tractable enough to support decisions. The medicine article also follows his methods into infectious-disease modeling. This is a useful investigator-level example of mathematical techniques moving between different physical systems. [[wiki/PHOENICS|PHOENICS]] supplies the research-group context. Model quality and uncertainty must still be evaluated for each receiving application. ## Connected entries [[wiki/PHOENICS|PHOENICS]] · [[wiki/Oden Institute|Oden Institute]] · [[wiki/Defense Threat Reduction Agency|Defense Threat Reduction Agency]] · [[wiki/Reduced-Order Modeling|Reduced-Order Modeling]] · [[wiki/Scientific Machine Learning|Scientific Machine Learning]] ## Sources and corpus context - [[research/The Austin Executable Loop|The Austin Executable Loop — master document]] - [[research/Oden Institute - Machine Learning, Medicine, and Terrorism|Oden Institute - Machine Learning, Medicine, and Terrorism]] - [Probabilistic and High Order Inference, Computation, Estimation, and Simulation](https://oden.utexas.edu/research/centers-and-groups/probabilistic-high-order-inference-computation-estimation-and-simulation/) - [Minimizing Uncertainty in the Uncertain World of Defense, Energy](https://oden.utexas.edu/news-and-events/news/minimizing-uncertainty-in-uncertain-world-of-defense-energy/) **Cluster:** [[wiki/Austin Executable Loop|Austin Executable Loop]] · [[wiki/Austin Research Evidence Map|Austin Research Evidence Map]]
