About Me

Hi! I’m Gareth 🐙, also known as grhkm online. Warwick Maths BSc'24, ??? Maths MSc'25. I play CTF in my (drastically decreasing) spare time.

As of July 2023, I am currently doing an internship with Russell Lai from Aalto University on lattice-based cryptography.

I like isogenies, heavily inspired by yx7 / Lorenz and his CTF challenges. Also jo_k_er / Jonathan’s, challenge at KalmarCTF 2024.

I am now looking for a Masters position! Please reach out to me if you are aware of any.

Random facts about myself:

• I type relatively quickly. My personal record is 186wpm for 60 seconds, which places me on 288th globally.
• I stan NewJeans Hanni and Twice Jeongyeon.
