My name is tux.

I am a Founding Cryptography Engineer for NuCypher working on Proxy Re-encryption (PRE) and Fully Homomorphic Encryption (FHE). At NuCypher, I have authored pyUmbral, and the NuCypher PRE network. I am the author of Sputnik, the ETHBerlin 2018 winning hackathon project wherein we executed the first-ever fully homomorphic smart contract. I currently act as a Director on the board of the Loki Foundation, the nonprofit behind the Loki Network, a fork of Monero that implements a mixnet for privacy-preserving applications based on proof-of-stake, and Session, a decentralized end-to-end encrypted messenger based on Signal that offers resistance to metadata leakage. Additionally, I act as a Cryptography Advisor to their development team.

My main interests involve cryptography and other privacy-preserving technologies, information security, distributed networks, and startups. I almost exclusively work on or with startups because they are frequently a powerhouse of innovation in the world.

I am a firm believer in Radical Privacy and privacy insurrectionism. I define radical privacy as a method of direct-action against authoritarian power that desires to restrict our collective and individual freedoms through technology that owns, controls, or restricts our personal data. We have a responsibility to insurrect against those who are seeking to oppress us with these tools.

If you require cryptography or security expertise for something you’re working on, feel free to contact me via email. If you’d prefer to communicate over an encrypted channel, email me first and we can organize something.
