ABOUT

I am an Assistant Professor of Computer Science at Georgia Tech with an adjunct appointment at the School of Electrical and Computer Engineering. My research focuses on rack-scale computing and network-compute integration, targeting the most challenging communication-intensive services with tight latency targets in datacenter environments. Blurring the boundaries between network and compute, and pushing functionality with richer semantics to the network endpoints paves the way for high-performance, efficient and scalable microsecond-scale services. I am also broadly interested in the ongoing transition from CPU-centric to network- and memory-centric computing and the impact of this paradigm shift in the evolution of system architectures, algorithms, and software.

During my PhD at EPFL, I was the architect of Scale-Out NUMA, a rack-scale architecture, programming model and communication protocol designed to deliver low-latency and high-bandwidth access to remote memory, enabling memory pooling in scale-out deployments. My thesis entitled Network-Compute Co-Design for Distributed In-Memory Computing was awarded an EPFL thesis distinction and the ACM SIGARCH/IEEE CS TCCA Outstanding Dissertation Honorable Mention. I am a recipient of the NSF CAREER award, a Google Faculty Research award, and several teaching distinctions at Georgia Tech. My research is supported by the NSF, IARPA, Intel, and Samsung.
