    Bio
    I am a professor at Tel Aviv University's School of Computer Science, and a research scientist at Columbia University's Computer Science Department.
    My research focus is information security, cryptography and algorithms. I am particularly interested in what happens when cryptographic systems meet the real world, where computation is faulty and leaky.
    I cofounded SCIPR Lab, where we construct cryptographic zero-knowledge SNARK proof systems for ensuring the integrity of computation conducted on untrusted, faulty and malicious platforms.
    I'm interested in blockchain-based cryptographic protocols, and am a founding scientist of the Zcash privacy-preserving cryptocurrency which implements our Zerocash protocol.
