Eric Du

Hello there!

I am a recently-graduated student from UC Berkeley (2025), with BAs in both Physics and Computer Science. I am currently a post-baccalaureate researcher working in superconducting qubit fabrication at the Molecular Foundry at Lawrence Berkeley National Lab, under the direct supervision of Dr. Yashwanth Balaji. I also work with Dr. Yen-Yung Chang on RF simulations in Ansys HFSS, where we are investigating ways to mitigate spurious resonance modes found in many superconducting chip packages. In my free time, I enjoy playing the piano, badminton, and occasionally some gaming.

I made this website as a way to document the various projects I’m involved in, and occasionally post whenever I feel like it. Have a look around!
