# Moor Xu — Weighted Graphs

## Interview by Sheila Ramaswamy

**Can you tell us a bit about the project you are working on?**

My project is on expanding the theory of weighted graph limits. A graph is a mathematical object with vertices and edges that can be used to model real world phenomena such as the internet; I am working with limits of sequences of graphs as they become denser and more complicated.

**What made you interested in doing research? How did you get interested in the specific topic you are researching?**

**What types of challenges did you encounter while doing you research? Were you able to overcome them?**

In mathematics, it’s easy to get stuck on a problem. There were a few times when my project stalled because I didn’t understand a basic definition or couldn’t figure out how to show a result. It often feels like I’m bashing my head against a wall for a few days at a time, but when I keep working and asking questions, I eventually get some key insight and understand a bit more about my problem. That feeling of realization is what makes math feel so rewarding, and that’s what I’m always working toward.

**What advice would you give to other students interested in doing research?**

My advice is that they should definitely pursue the opportunity to do research. They should make friends with professors and ask them about their research, and find a common topic of interest. Treat research as a learning experience, and try to discover something cool!
