Εxperience

• August 2014 - May 2020: PhD in Computer Science
  • City University of New York
    • Introduced a new class of cryptographic objects where the holder of the secret key is limited in several ways such as they cannot clone the key or they can only use it a fixed number of times.
    • Designed applications including a decentralized cryptocurrency protocol without the need for a blockchain.
• Winter 2019: Cryptography Consultant
  • ThunderCore, California
    • Reviewed cryptographic code and confirm an attack on a previous version of a cryptographic protocol for signature aggregation.
    • Compared existing libraries implementing the [Boneh, Lynn, Shacham] signature aggregation scheme.
    • Provided additional resources and answer cryptographic questions to the Core team.
• Summer 2018: Software Engineering Intern
  • ThunderCore, California
    • Designed and developed in Solidity several versions of smart contracts for 1 vs 1 fair randomness generation using modifications of coin-flipping protocols.
    • Unit, functional and manual testing of smart contracts for randomness generation, Ethereum Name Service and Timestamping contracts, ERC-20 and ERC-721 tokens.
• Summer 2017: Research Intern
  • IOHK and University of Edinburgh, United Kingdom
    • Compared different post-quantum signature schemes according to key/signature size and signing/verification times and their applicability to quantum-secure blockchains.
    • Designed a quantum money protocol without need for a public common ledger and with classical communication. The protocol makes use of a modification of quantum lightning.

Education
