I am a senior undergraduate studying Electrical and Computer Engineering at Cornell University with a music minor. I am an undergraduate TA for the course Intro to Computing Using MATLAB. My academic interests within my major lie primarily in signal processing.

My biggest MATLAB project has been developing a programmable audio synthesizer and music visualizer, with fellow Cornell undergraduate Andy Wang. Check out our YouTube channel here:
