I am currently a Postdoctoral Researcher in the System Software Research Group at Virginia Tech, which is led by Binoy Ravindran.

Research Interests

These include Operating Systems, Performance Scalability , File Systems, and Power Consumption, Multicore and Manycore Architecture Design.

Ph.D. Thesis

I obtained my Ph.D thesis in June 2016 from the UPMC university, Paris, France. The French title is "Système de fichiers scalable pour architectures many-cores à faible empreinte énergétique" which means "Scalable File System for Energy-Efficient Manycore Architectures". It was supervised by Alain Greiner and co-supervised by Franck Wajsburt.


Recent advances in processor manufacturing led to the integration of hundred if not thousand of cores in a single chip: many-core processors. TSAR is a power-efficient many-core architecture that use 32-bit core while extending physical addresses to 40-bit. Considering this architecture as a base, we have modified a UNIX-like OS to implement a scalable file system that fully explores the extended physical address space. The solution restructures the kernel as a multikernel: multiple kernel instances communicating through message passing.
