# About Me

I am a fifth-year graduate student at the University of Wisconsin-Madison. I am currently interested in nonlinear algebra. My advisor is Jose Rodriguez. Currently, I am working kinematic projects under the supervisor of Paul Milenkovic from the ECE department.

## Hobbies

I play the violin since the age of four, and I am an avid fan of classical music. My favorite piece is "Chaconne" in BWV 1004 by Bach, which is as deep, elegant, and precise as Math.
