Hi, I’m Christina O’Donnell, and I have a deep passion for Computer Science. From a young age, I’ve been captivated by computers and the intricacies of how they work. My journey led me to study Maths and Computer Science at Oxford. After completing my degree, I worked as a software engineer for six years, developing a data analytics program. I then decided to take a slightly different path in my career, to become a Computer Science tutor, allowing me to pursuing my research interests concurrently. This September (2024), I am excited to be starting an MSc in Computer Science at Nottingham. I’m hoping that this will be a step forward toward building a career in research.

While I am still early in my academic career, I have formed initial interests in the areas of Dependent Type Theory, Functional Programming, Formal Verification, and Term Graph Rewriting Systems.

Projects #

Here are some of my projects I’ve done over the years. You can find additional projection on my GitHub page.

Semantic Graphs - Conducting research on ‘Graphical Pattern Calculus’ as a term rewriting system, and an investigation into formal language, expression, and variable binding.

Guix Contributor - Contributor to Guix– the project to build a fully functional package manger and reproducible operating system in Scheme.

Interactive Quantum Tunnelling Simulation - Created a simulation using Processing JS, allowing for interactive manipulation of variables. You can see the code and tweak the variables on Khan Academy. And there’s a discussion on this Reddit thread.

Octocurious Blog - Maintainer a blog with regular posting of technical content. Blog source, and its theme.

System hosting - Running and maintaining multiple Linux servers, self hosting websites, GitLab, email, DNS, Discourse. Maintaining security policy, updates, logging, and firewalls.

Text Editor - Developed a very text editor for in C, using a gap buffer for (somewhat) efficient text storage and manipulation. See the code on GitHub.

2D Physics Engine - Made a 2D rigid-body physics engine from scratch in C++, featuring collision detection, multiple collision points per object pair, and joint support. It has platform support for Windows and Linux. See the code on Github.
