# David Jao

I am a professor in the Faculty of Mathematics (*https://www.math.uwaterloo.ca/*) at the University of Waterloo (*https://www.uwaterloo.ca/*), working in the Department of Combinatorics and Optimization (*https://uwaterloo.ca/combinatorics-and-optimization/*). I am also:

- A member of the Cybersecurity and Privacy Institute (
*https://uwaterloo.ca/cybersecurity-privacy-institute/our-people*), - An affiliated member of the Institute for Quantum Computing (
*https://uwaterloo.ca/institute-for-quantum-computing/programs/graduate-studies/supervisors*), - Chief Cryptographer at evolutionQ (
*https://evolutionq.com/about.html*).

My research interests are in the areas of number theory (*https://en.wikipedia.org/wiki/Number_Theory*) and cryptography (*https://en.wikipedia.org/wiki/Cryptography*), with
emphasis on elliptic (*https://en.wikipedia.org/wiki/Elliptic_Curve_Cryptography*) and hyperelliptic curve cryptography (*https://en.wikipedia.org/wiki/Hyperelliptic_Curve_Cryptography*). The focus of my recent work is on post-quantum cryptography (*https://en.wikipedia.org/wiki/Post-quantum_cryptography*) and isogeny-based cryptography (*https://en.wikipedia.org/wiki/Supersingular_isogeny_key_exchange*).

Prior to joining the University of Waterloo, I was a post-doc researcher in the Cryptography and Anti-Piracy Group (*https://research.microsoft.com/en-us/um/redmond/groups/crypto/*) at Microsoft Research (*https://research.microsoft.com/*). I received my Ph.D. in Mathematics (*http://www.genealogy.ams.org/id.php?id=71888*) from Harvard University (*http://www.math.harvard.edu/*) under the supervision of Noam Elkies (*http://www.math.harvard.edu/~elkies/*).
