I am a Ph.D. student at the University of Lugano, where I am serving as a research assistant in Distributed Systems groups under the supervision of Prof. Fernando Pedone.

Research

My research interests include dependable distributed systems and distributed data management systems.

I am currently working on using RDMA network to boost the performance of distributed systems. In particular, we are interested in using RDMA's shared-memory model to build fault-tolerant systems that are both scalable and strongly consistent.

Recently, I contributed to the development of the following projects:

  • (One more to appear soon)

  • RamCast: an atomic multicast protocol for the shared-memory system model by leveraging RDMA technology [paper, code]

  • DynaTree: a distributed and replicated B+Tree that guarantees strong consistency [paper, code]

  • DynaStar: a dynamic partitioning scheme for scalabling State Machine Replication [paper, code]
