I am currently an Advanced Research Scientist at VORTEX Colab, a new industrial Research and Innovation (R&I) lab for Altran Portugal. I am building and leading the Cybersecurity and Distributed Systems R&I team.

I am interested in understanding and building secure, resilientscalable, available, and efficient distributed systems. More recently, my focus is on the automotive industry (Cybersecurity and Telecom.).

I hold a Joint PhD degree in Computer Science obtained from the University of Toulouse and the Lebanese University, in 2012. My PhD thesis topic was on Adaptive Byzantine Fault Tolerance, currently known as Blockchains/Distributed Ledgers. I'm privileged to have been mentored by Prof. Rachid Guerraoui at EPFL during my thesis.

Prior to VORTEX, I've been an Assistant Researcher at INESC TEC (HASLab research unit), Portugal, and an Invited Assistant Professor at the Department of Informatics of University of Minho and at MAP-I PhD school, Portugal. Before that, I worked as Postdoc at INSA de Lyon (France) and Intern twice at EPFL (Switzerland). My research work spans BFT/Blockchains, Anonymous Communication, Cloud/Fog/Edge Computing, and data management (Conflict-free Replicated DataTypes - CRDTs).
