Hewlett Packard Enterprise Labs


I'm Diman Zad-Tootaghaj, I am a research scientist at Hewlett Packard Labs in Palo Alto, California. I work on Serverless Computing, Network Programmability, SmartNics, Software-Defined Network solutions in Wide Area Networks (SD-WAN), Edge as a Service, Serverless Orchestration and Auto-scaling, Optimization algorithms and Consensus protocols.

I earned my PhD in Computer Science and Engineering at Pennsylvania State University. Prior to Penn State, I got my B.Sc degree in Electrical Engineering at Sharif University of Technology, Iran. During my PhD, I was working in the Institute for Networking and Security Research (INSR) and Network Sciences Research Group (NSRG) under supervision of Prof. Thomas La Porta (advisor), Dr. Ting He (co-advisor), and Dr. Novella Bartolini.

My research area is computer networks, stochastic analysis, operating system, and parallel computing. I graduated from Sharif University of technology, with MSc. in Electrical Engineering.

My recent contribution is GTNS (Game-Theoretic Network Simulator). You could also find the related publications as linked in this website.
