Hi, welcome!

I am a fifth-year Ph.D. student in Computer Science at the University of California, Berkeley. I am advised by Professor Alvin Cheung. I am a part of EPIC Data Lab and Sky Lab (formerly RISE Lab). I am interested in Efficient Video Inference Systems.

I graduated with a Combined Bachelor's/Master's program in Computer Science and Engineering from the University of Washington in 2021. I worked in the UW Interactive Data Lab as a research assistant, mentored by Professor Jeffrey Heer. I interned at Google as a student researcher and DocuSign and OctoAI as a software engineering intern. Aside from academic works, I was a volunteer officer of Thai Students Association, coordinating social events and meetups for Thai students in the University of Washington.

Work Experience

  • 2026 - present

    ML Software Engineering Intern

    Meta (Meta Recommendation Systems Knowledge Team)

    (On-going) Design and implement efficient Video-LLM (with Dr. Litao Hu).

  • 2021 - present

    Graduate Student Researcher

    Sky Lab @ UC Berkeley

    Contirbuting to Apperception, a query language and a database management system for geo-spatial video data. I am working on designing the programming interface of Apperception DSL. I am also working on video query optimization, using geo-spatial metadata to reduce executions of expensive ML operations.

  • 2025

    Student Researcher (Intern)

    Google (SystemResearch@Google)

    Researched Gemini’s video understanding evaluation through auto-generated video-QAs. Develop scalable question auto-generation methods and a correctness verifier for the generated questions (with Dr. Samira Khan).

  • 2021

    Software Engineering Intern

    OctoAI

    Integrate the deep-learning models visualizers designed from previous year into optimizer tool (Octomizer) that optimizes deep-learning models compiled by TVM.

  • 2019 - 2021

    Graduate and Undergraduate Teaching Assistant

    Paul G. Allen School of Computer Science and Engineering @ UW

    Teaching CSE331 (Software Design and Implementation) and CSE442 (Data Visualization). Teaches supplemental materials in quiz section. Grade students' assignments. And, hold office hours for answering questions related to the class.

  • 2018 - 2021

    Graduate and Undergraduate Research Assistant

    Interactive Data Lab @ UW

    Contributing to Vega and Vega-Lite project; both are toolkits for creating visualizations. In Vega, I added support for automated labeling data points in charts. In Vega-Lite, I added support for visualizing data with error bar or error band chart.

  • 2020

    Software Engineering Intern

    OctoAI
