Research Interests

My research focuses on the intersection of distributed systems and high-performance computing (HPC), exploring how multiple HPC facilities can collaborate through event-driven architectures to solve complex problems with enhanced resilience and efficiency. To achieve this, we are developing a hierarchical event fabric designed to advance both scientific applications—such as AI-guided simulation campaigns, time-sensitive data analysis pipelines, and distributed data integration—and resilience-enabling solutions, including a policy engine, resilient compute pools, and resilient data views. For more details on this DOE-funded Diaspora project, please refer to the project description and publications c17 and c18 in my CV.
