Justin Kang

Welcome to my website. You can find my Publications, Projects and CV above. Below, you can find some information about me.

  • I am a Graduate Student at the University of California, Berkeley, affiliated with the BAIR Lab and supervised by Prof. Kannan Ramchandran.
  • Previously, I completed my Master’s of Applied Science at The University of Toronto supervised by Prof. Wei Yu.
  • My research interests include machine learning, privacy in learning, and data valuation. Recently, I’ve been working on applying some ideas from sparse signal processing to explainable AI for LLMs. I have a strong background in signal processing and information theory, and like to view machine learning problems through that lens, which often leads to unique and exciting solutions.
  • In 2019 I received my B.A.Sc. from the University of British Columbia in Engineering Physics.
