About

I'm Daniel Andrasz, a full time MSE student studying semiconductor and device physics and fabrication.

After hopping between multiple majors, I ended up pursuing my bachelor's in material science & engineering at UIUC. My academic background consists of courses spanning basic material science to compound semiconductor device physics, CA'ing multiple ECE courses, and participating in undergrad research.

In my freetime, I play video games, lift weights and boulder.
