👋🏽 Hello, and welcome to my website! My name is Pramana Saldin and I am a fourth-year undergraduate at the University of Wisconsin.
I am a 2025 Barry Goldwater Scholar. This summer, I am conducting research for the SMALL REU (number theory and probability). I’m interested in algebra.
For the details of this site: I use Hugo with a modified Archie theme. This site is deployed through GitHub Pages.
If you want to reach out, you can contact me on my Mathstodon or by email: [lastname] [at] wisc [dot] edu.
