# Omar Ghattas **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. **Omar Ghattas** is an Oden computational scientist appearing in the [[wiki/PECOS|PECOS]] lineage and the institute’s relationship with large-scale computing. The succession article identifies his leadership-science roles with Frontera and [[wiki/Horizon|Horizon]]. His place in this cluster connects [[wiki/Inverse Problem|inverse problems]], large numerical models, and the machines needed to execute them. The relationship illustrates how algorithm design and computing infrastructure develop together: more ambitious inference requires scalable methods, while greater compute enables more complex models and repeated uncertainty analysis. ## Connected entries [[wiki/Oden Institute|Oden Institute]] · [[wiki/PECOS|PECOS]] · [[wiki/Texas Advanced Computing Center|Texas Advanced Computing Center]] · [[wiki/Horizon|Horizon]] · [[wiki/Inverse Problem|Inverse Problem]] ## Sources and corpus context - [[research/The Austin Executable Loop|The Austin Executable Loop — master document]] - [[research/Oden Institute - The Austin Succession Stack|Oden Institute - The Austin Succession Stack]] - [UT Austin Wins $17 Million Grant from Department of Energy for Computational Research](https://news.utexas.edu/2008/03/07/the-university-of-texas-at-austin-wins-17-million-grant-from-department-of-energy-for-computational-research/) - [After a Decade of Pioneering Digital Twin Research, UT Emerges as a Global Leader in AI for Science](https://news.utexas.edu/2026/02/27/pioneering-ai-for-science-why-ut-is-a-digital-twin-powerhouse/) - [A Powerful Vision — The Synergistic Relationship of High-Performance Computing and the Oden Institute](https://oden.utexas.edu/news-and-events/news/TACC-high-performance-computing-and-the-Oden-Institute/) **Cluster:** [[wiki/Austin Executable Loop|Austin Executable Loop]] · [[wiki/Austin Research Evidence Map|Austin Research Evidence Map]]
