Research Interests:
Bio and Prior Work: Martonosi’s research interests are in computer architecture and mobile computing, with an emphasis on energy-efficient systems. In the field of processor architecture, she has done extensive work on power modeling and management and on memory hierarchy performance and energy. This has included the development of the Wattch power modeling tool, the first architecture level power modeling infrastructure for superscalar processors. In the field of mobile computing and sensor networks, Martonosi led the Princeton ZebraNet project, which included two real-world deployments of tracking collars on Zebras in Central Kenya.
Current and Future Projects:
1) In the processor architecture area, Martonosi’s group is currently exploring system-level interfaces to allow nimble management of power, performance, and parallelism tradeoffs in chip multiprocessors and MPSoCs.
2) She is also researching power-performance control problems in large-scale data centers. Her students are studying a range of optimizations that are either localized within single data centers or spread across regionally-distributed data centers. Together, these techniques are aimed at reducing data center energy usage, better managing workload and power spikes, and better optimizing the use of electricity acquired from green sources.
3) Martonosi’s work in mobile computing includes projects improve the location-awareness of mobile cellphone apps, while also abiding by privacy and security expectations. This includes a mix of cross-phone collaboration, location modeling/estimation, and other techniques. Her group is also leading the C-LINK effort which uses mobile computing techniques to bring cost-efficient, low-latency internet access to developing regions.
