Nicholas (Nick) Genise

I am a Senior Cryptography Research Scientist at Apple. My main research interests are lattice-based cryptography and fully homomorphic encryption together with its applications. In general, I am interested in cryptography. Previously, I was a Scientist at Duality, an Advanced Computer Scientist at SRI's Computer Science Lab, and a postdoctoral researcher in the Rutgers mathematics department supervised by Stephen Miller. I graduated with a Ph.D. in ECE from UCSD in September 2019, advised by Daniele Micciancio. Prior to UCSD, I graduated with a B.S.E. in Electrical Engineering from the University of Michigan, Ann Arbor in 2013.
