I am a senior researcher at INESC TEC (HASLab research unit) and invited assistant professor at the Department of Informatics of University of Minho, Braga, Portugal. I hold a PhD from the University of Toulouse, advised by Jean-Paul Bahsoun and mentored by Rachid Guerraoui. I've spent some time at IRIT (France), INSA de Lyon (France), and EPFL (Switzerland) twice in the past.

I am interested in understanding and building correct, scalable, available, resilient, secure, and efficient distributed systems. 
Currently, I am working Edge Computing (based on Conflict-free Replicated DataTypes), and Blockchain and Cryptocurrencies (PoW, PoX, and BFT).

News. (by Nov 2017)
October 2017: I presented my paper on  "Sustainable Blockchain through Proof of eXercise" at IEEE NCA'17 in Cambridge, MA.
