His doctoral thesis is titled “Applications of Classical Algebraic Geometry to Cryptography.” [\\[6\\]](#cite-id-X6uo34KAca4c8kZf) [\\[3\\]](#cite-id-EO9w29CISwK1S93b)​\n\n## Career\n\nHerold's career is marked by a transition from theoretical academic research to applied cryptography within the blockchain industry.\n\n### Early Academic Career\n\nBefore joining the [Ethereum Foundation](https://iq.wiki/wiki/ethereum-foundation-ef), Herold was an active academic researcher within the German cryptography community. His early work, with publications dating back to 2010, centered on public-key cryptography. During this time, he co-authored papers on topics such as fully anonymous group signatures with verifier-local revocation, structure-preserving signatures, and constant-size anonymous credentials. His collaborators included respected cryptographers such as Johannes Buchmann and Eike Kiltz, highlighting his strong foundation in the academic field. [\\[4\\]](#cite-id-FzCRoxIhMrGG7tW6)​\n\n### Ethereum Foundation\n\nHerold is currently a researcher on the Cryptography Research Team at the [Ethereum Foundation](https://iq.wiki/wiki/ethereum-foundation-ef). [\\[4\\]](#cite-id-FzCRoxIhMrGG7tW6) In this role, he applies his expertise to solve foundational challenges related to the security, scalability, and long-term viability of the [Ethereum](https://iq.wiki/wiki/ethereum) network. He works alongside other prominent researchers, including [Dankrad Feist](https://iq.wiki/wiki/dankrad-feist), [Dmitry Khovratovich](https://iq.wiki/wiki/dmitry-khovratovich), and [Benedikt Wagner](https://iq.wiki/wiki/benedikt-wagner). [\\[1\\]](#cite-id-3bWw2MB9kxkBj4Ds) His research directly anforms the development and implementation of major network upgrades, such as the transition to Verkle trees and the implementation of Proto-Danksharding ([EIP-4844](https://iq.wiki/wiki/eip-4844)), while also exploring future-proofing the network against quantum threats.
