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, 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 applying some ideas from valuation/importance scoring to explainable AI for LLMs (see paper 1 below). I have a strong background in signal processing and information theory, and like to view these modern 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.

Recent News

• My paper Learning to Understand: Identifying Interactions via the Mobius Transform has been accepted to NeurIPS!
• A recent article about Federated Learning that I was interviewed for.
• I’m happy to anounce that my paper has won the 2024 IEEE Communication Society and Information Theory Society Joint Paper Award. This is one of two paper awards
• I’ll be joining Google for summer 2024 as a Student Reseacher, working on a project with the Google Cloud Platforms Systems Research Group (SRG) hosted by Kun Lin and Prof. David Culler.
