About

I am the CEO, President and Co-Founder of softwareQ Inc, and a researcher at the Institute for Quantum Computing, working with Michele Mosca on theoretical aspects of quantum computation and (post-quantum) cryptography. I am also collaborating on quantum risk assessment with evolutionQ Inc.

I am involved in the CryptoWorks21 Quantum-Safe Cryptographic Infrastructure Program and I am a member of the European Telecommunications Standards Institute (ETSI) Quantum-Safe Cryptography Standardization Group.

I graduated from Carnegie Mellon University with a PhD in Theoretical Physics. My advisor was Robert B. Griffiths.

Curriculum Vitae as of July 2017

"Try not to become a man of success,
but rather try to become a man of value"
Albert Einstein
