Patrick Longa
I am a Principal Researcher with the MSR Security and Cryptography
group at Microsoft Research
in Redmond, USA.
I completed my Ph.D. in Electrical and Computer Engineering at the University of Waterloo in 2011, after which I occupied a post-doctoral research position in the Department of Combinatorics and Optimization (C&O) of the same university, under the supervision of David Jao. During my time at Waterloo, I was a member of the Centre for Applied Cryptographic Research (CACR)
and the Laboratory for Side-Channel Security of Embedded Systems.
My research interests mainly involve (post-quantum) cryptography, elliptic curve and pairing-based cryptography, efficient algorithmic design, high-performance implementation of cryptographic primitives, and countermeasures against side-channel analysis.

I am member of the editorial board of the Journal of Cryptographic Engineering (JCEN).
I served as program co-chair for LATINCRYPT 2021.
I served as guest editor for IEEE Transactions on Computers' Special Issue on Cryptographic Engineering in a Post-Quantum World.
