Dr Antonella Del Pozzo is a research engineer at CEA-List. She has a joint PhD in distributed system from Sapienza University of Rome and Sorbonne University of Paris. Her research focuses on the blockchain as a distributed object, formalizing its properties and solvability. She is an expert in the so-called classical BFT-Consensus algorithms. She worked on the correctness analysis of the Tendermint Core consensus algorithm and collaborated with Nomadic Labs for the Tenderbake specification (now run in the Tezos blockchain). Besides consensus, her research spans over other blockchain topics, such as accountability, fairness, interoperability, and web3.
