> Hi, I'm Alexandra! I'm a junior at Columbia University studying Mathematics and Computer Science. I'm interested in software, AI/ML, biotech, and design.

In my spare time, I read essays and sci-fi, make stickers for my laptop, play Set, scroll Wikipedia pages on music history with Columbia Quiz Bowl, and am a mediocre birdwatcher.

Talk to me anytime at alexandra [dot] duan [at] columbia [dot] edu.

$ cd "research"

I am currently developing a hybrid machine learning model for hazard analysis in chemical engineering at the Complex Resilient Intelligent Systems Lab @ Columbia. Previously, I worked on a Python-based pipeline to quantify blood flow in an Alzheimer's mouse model through the Simons Summer Research Program, which was published here.

$ ls "programming experience"

I like to program

in: Python Java C/C++ JavaScript HTML/CSS Bash
using: React Node.js Express Socket.IO Firebase VSCode (light mode)

I previously interned as a software engineer at Google. I am a teaching assistant for Columbia's COMS3203: Discrete Mathematics, where I think very hard about the mathematical foundations of computer science.

You can find my projects on my GitHub.
