Ji-Jia Wu | 吳季嘉

I am a software engineer at Google, currently working on on-device ML and LLM applications. My experience in Machine Learning spans from academic research during my undergraduate and master's studies to real-world applications in my current role.

I've published two papers in CVPR 2022 and CVPR 2024, contributing to the field of computer vision. During my Master's program, I was honored with the Presidential Award for Graduate Students, granted to the top 1% of students.
