Wissam Ghantous
Assistant Professor
Hello! Welcome to my website.
I am a tenure-track Assistant Professor in the department of Mathematics of the University of Central Florida, as well as a member of UCF's Cyber Security and Privacy Cluster.
Previously, I was a postdoctoral researcher for one year at the École Normale Supérieure (Paris). Before that, I completed my PhD at the University of Oxford in 2023.
My main research interests are post-quantum cryptography and computational number theory.

*The picture below is the supersingular isogeny graph Λ1873(2, 3) that I generated using SAGE. The prime 1873 is the smallest p such that both supersingular isogeny graphs Λp(2) and Λp(3) have no loops. Read more on this in my first paper.
The picture at the very top of this webpage is the beautiful Swiss landscape that can be seen from the top of the Uetliberg TV-tower (taken during the sectional ICM of 2022).
