Luca Nizzardo is Cryptography Research Scientist at Protocol Labs, where I work on crypto-related problems involving Filecoin. Before joining Protocol Labs I did my PhD in Cryptography at Madrid Institute for Advanced Studies in Software under the outstanding supervision of Dario Fiore. I'm broadly interested in Blockchain related problems involving cryptography, like Zero Knowledge Proof Systems, Contingent Payments, Consensus Algorithms. Moreover, I have been working on cryptographic techniques for the security of the Cloud since 2014, with a particular focus on homomorphic primitives. Before starting my PhD, I have been a business intern at IBM Italy in the Global Business Services division (Fall 2013) and a research student at City College of New York under the supervision of Rosario Gennaro (Spring 2013). During the Spring 2017 I was visiting Rosario Gennaro at City College fo New York, working with him on a new primitive called Zero Knowledge Contingent Service Payments, which extends the functionalities of Zero Knowledge Contingent Payments over the Blockchain. I had the privilege to work on this project also with Matteo Campanelli (CUNY) and Steven Goldfeder (Princeton). In the last year, while pursuing my PhD I've been also working on consultancy projects involving Cryptography, Blockchain and Cryptocurrencies.
