Her research interests are in computer architecture. Her current work is primarily on energy and thermal efficient systems for multimedia and communications applications, as part of the Illinois GRACE and 4-PEAC projects. Her past contributions are in the areas of memory consistency models, exploiting instruction-level parallelism (ILP) for memory system performance, and evaluation techniques for shared-memory multiprocessors with ILP processors. She led the development of the widely used RSIM architecture simulator.
