Our paper "CTIDH: Faster constant-time CSIDH" is online!
A collaboration with
Gustavo Banegas, Daniel J. Bernstein, Fabio Campos, Tung Chou, Tanja Lange, Michael Meyer, Benjamin Smith.
Check out the
website with the paper and the software.
The paper is also on eprint as Report 2021/633.
Our paper "Explicit connections between supersingular isogeny graphs and Bruhat--Tits trees"
with Laia Amorós, Annamaria Iezzi,
Kristin Lauter and Chloe Martindale is on
The current version is also accessible here.
I have given two talks about the paper and you can see my exposition in these notes
here. Please contact me with any comments!
I will be a TA at the (online)
PCMI 2021 Graduate Summer School (July 26-30, 2021) for the course of Kristin Lauter
on Supersingular Isogeny Graphs in Cryptogprahy.
In Spring 2021, I am running a reading group at QuSoft on quantum algorithms for isogeny problems.
(7/23) I gave a talk at the student-organized ANTS summer school on
"Elliptic curves, isogenies, and endomorphism rings".
The talk is available on Youtube
and the write-up is here (rough draft but includes references and comments).
I gave a talk at the
Linfoot number theory seminar in Bristol.
(6/03) I will be at the Isogeny-based cryptography summer school
in Bristol, December 14-18 2020.
I will be giving a talk about my work in the afternoon QSC session of the
Dutch Mathematical Congress (NMC). Links to the
abstract and for the conference
Unfortunately, the NMC has
been cancelled but might still happen at a different date.
(2/14) Breaking DDH with genus theory with Wouter Castryck and Fre Vercauteren is out! The eprint article is

(1/20) I will be a TA for the course on Supersingular Isogeny Graphs by Kristin Lauter during
Park City Mathematical Institute 2020
in July 2020. (7/23) The program has been rescheduled to July, 2022.
I was a visiting graduate student at the The Quantum Wave in Computing
semester program at the Simons Center from Jan 20 to Feb 7, 2020.
