• End-User Data Delivery
• Bringing Neutron Science data and simulations to the TeraGrid
• Bulk Data Transfer Forecasts and the Implications to Grid Scheduling - Ph.D. Dissertation Work

  This involved research and development on Data Grid tools and techniques in conjunction with Argonne's Distributed Systems Laboratory. My doctoral work was based on Globus Data Grid - built techniques to locate data in highly replicated environments; developed performance prediction strategies for bulk Data Grid transfers aiding data transfer schedules; developed co-allocation middleware enabling parallel and fast access to replicated data, etc. More details in the publications page.
