Systems for AI infrastructure

Co-designing memory, network, and compute for AI at scale.

I am a Senior Research Engineer at the Barcelona Supercomputing Center (BSC-CNS). My work spans GPU memory hierarchies and DRAM architecture, datacenter networks and in-network computing, and distributed ML execution, combining hardware–software co-design with measurement-driven analysis of real-world workloads.

Research areas

Four connected threads with one goal: AI and datacenter infrastructure that is more performant, efficient, scalable, and predictable.

Open to collaboration

I am particularly interested in co-designing the memory, network, and processing layers of future AI infrastructure, with academic and industry partners alike.
