About me

I am a cloud software architect working on network programmability and applications of network telemetry (TCP-INT). Before that, I was a postdoctoral researcher at Stanford University in the Platform Lab and the McKeown group. My research interests are in distributed systems, networking and databases. I received my PhD from Università della Svizzera italiana (USI), where I was advised by Prof. Robert Soulé and Prof. Fernando Pedone. My dissertation, "Building Blocks for Leveraging In-Network Computing", explores the abstractions that applications can use to harness programmable networks.
