About Me

Hello, I'm Lewis Napper, a PhD mathematics student from the University of Surrey in the United Kingdom. My research focuses on applications of abstract geometry to problems in the theory of partial differential equations, fluid dynamics, and relativity. Outside of my work in academia, I am an artist and occasional programmer, with an interest in game development and computer graphics.

This site is a showcase of my work and hobbies across various fields, acting as a catalogue of my academic career, artistic endeavours, and other exploits. Should you discover a problem, bug, or error, please feel free to file an issue on this website's associated Github Repository or Contact Me. Explore to find out more or take a look at my CV.

Hades II Bug Testing

Updated: 16th June 2024

I am currently taking part in the Early Access period for Supergiant Games' next masterpiece, Hades II. As part of the game's continued development, Supergiant Games have included a bug report tool, which allows players to provide QA feedback. Issues resolved following my reports include: delayed dialogue, enemies spawning out of bounds, persistent visual effects, and inaccesible doorways.
