I am working on:
- post-quantum cryptography, especially isogeny-based cryptography,
- computational number theory,
- quantum algorithms used for cryptanalysis.

-
My paper "Adventures in Supersingularland" has been published in Open Access at Experimental Mathematics.
https://doi.org/10.1080/10586458.2021.1926009 This is joint work with Sarah Arpin, Catalina Camacho-Navarro, Kristin Lauter, Joelle Lim, Kristina Nelson and Travis Scholl. - I recorded a talk for the CTIDH paper at CHES 2021. The video is available here on Youtube, the paper is available here, and the paper and software in their latest version are also available at ctidh.isogeny.org.
- I will be on the poster committee for Alice & Eve 2021! The deadline to submit your poster is October 15, 2021 and the event will happen in Nijmegen on November 12, 2021.
- I lectured about the DDH paper at the Isogeny School. Notes are available here. Scribbles from Aug 12 sessions: morning session and evening session.

During July 26-30, 2021, I was TAing for Kristin Lauter at the PCMI Graduate Summer School 2021.
Videos from the lectures will be available at the PCMI YouTube channel.
Materials are available here. - 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.
