I am a PhD student at Notre Dame, studying Computer Science 📚
My published works explore topics in human perception-informed training, biometrics, computer vision, and AI/ML 📄
I create generative art under the name ten twentythree 🎨

I love writing algorithms that produce infinite, randomly variant works of generative art.
I post regularly on my Instagram. You can also view/interact with a selection of my work on my website.
This is a strictly hand-coded process -- no AI is used in the production of my work!
I write generative art using p5.js, a JavaScript creative coding library. In April 2026, I purchased a pen plotter, which I use to draw my algorithmically-generated works in physical mediums.
