About Me

Hi! I’m Tzu-Tao (Tommy) Chang (張子濤). I’m a 5th-year CS Ph.D. student at UW-Madison, advised by Prof. Shivaram Venkataraman. I’m interested in systems broadly, more specifically in ML systems and cloud systems. During my PhD, I’ve interned at Meta, Google, and AWS. I was also the recipient of Landweber NCR Graduate Fellowship in Distributed Systems.

Before joining UW-Madison, I received my B.A. in Finance with a minor in Computer Science and Information Engineering from National Taiwan University, where I was advised by Prof. Chung-Wei Lin.

I have a lovely dog named Coffee :)
