# PHOENICS **Domain:** Austin Research / Laboratories **Doc Type:** Research entity **Source basis:** Supplied research cluster with linked references; see the [[wiki/Austin Research Evidence Map|evidence map]] for verification scope. **PHOENICS** is Oden’s Probabilistic and High Order Inference, Computation, Estimation, and Simulation research group. Its methods include statistical [[wiki/Inverse Problem|inverse problems]], numerical approximation, uncertainty quantification, [[wiki/Reduced-Order Modeling|model reduction]], and computational inference. The master document identifies its [[wiki/Defense Threat Reduction Agency|DTRA]]-related work on nuclear-radiation effects as an explicit bridge between mathematical research and counter-WMD applications. [[wiki/Tan Bui-Thanh|Tan Bui-Thanh]]’s research illustrates the requirement to reconstruct an uncertain state with enough speed to inform a decision. The group belongs beside [[wiki/PECOS|PECOS]] in the wiki because it addresses related predictive problems through a distinct research organization. Their shared methods should remain connected without making the two centers interchangeable. ## Connected entries [[wiki/Oden Institute|Oden Institute]] · [[wiki/Tan Bui-Thanh|Tan Bui-Thanh]] · [[wiki/Reduced-Order Modeling|Reduced-Order Modeling]] · [[wiki/Inverse Problem|Inverse Problem]] · [[wiki/Defense Threat Reduction Agency|Defense Threat Reduction Agency]] · [[wiki/Verification Validation and Uncertainty Quantification|Verification Validation and Uncertainty Quantification]] ## Sources and corpus context - [[research/The Austin Executable Loop|The Austin Executable Loop — master document]] - [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]]
