About Zhepei

Hello, this is Zhepei's page. I am an Applied Scientist at Amazon Web Services (AWS) specialized in machine learning and audio (speech, music, etc.) signal processing. I am particularly interested in the applications of machine learning in audio domain, including source separation, speech enhancement, sound classification, audio synthesis, and multi-modal representation learning.

Before joining AWS, I earned my Ph.D. degree from the Department of Computer Science at the University of Illinois Urbana-Champaign (UIUC) in 2023, advised by Professor Paris Smaragdis. Prior to my Ph.D. program, I obtained my B.S. in computer science from Harvey Mudd College in May 2018.

Feel free to checkout my academic CV , Google Scholar, and LinkedIn profile.

I'm also an enthusiastic fan of classical music, an amateur piano player, and a licensed bartender.
