I am a third year Mathematics undergraduate at the University of Cambridge.
I write intuition-focused maths notes for come courses I've taken, books I've read, and various other things. You can contact me anonymously here.
If you want to have some fun, you can try a Python challenge I designed, from my days as a cybersec enthusiast.
Research
Denoising the Result of Monte Carlo Ion Implantation
Daniel Chen, Silvaco TCAD
Eight-week research project at Silvaco. One of the important processes during semiconductor manufacturing is implantation, in which a wafer is bombarded with ions to modify its electrical properties. Computer simulations of this process produce noisy results; in this project, a novel smoothing algorithm is developed that halves the mean-squared error compared to previous methods.
Associated Permutations of Complete Non-Ambiguous Trees
Daniel Chen, Sebastian Ohlig
Discrete Mathematics & Theoretical Computer Science, vol 25:2 (April 2024)
As part of PROMYS Europe 2022, I worked in a pair on a six-week research project in combinatorics, culminating in proving an open conjecture at age 17. We established a new bijection from upper-diagonal CNMs to tree-like tableaux, and after the program we continued to discover new ideas, defining a novel row-and-column swapping operation.
