About

I'm studying Statistics, Data Science, and Economics at UC Berkeley. I currently work as a URAP Research Assistant at UC Berkeley on AI nutrition and food systems research, an Undergraduate Research Assistant in the Data Science Discovery Program, a Student Researcher on the Rapid Reviews\Infectious Diseases AI peer-review evaluation team, and an Undergraduate Student Researcher at the William and Barbara Leonard Transportation Center. From May to August 2026 I was a Full Stack Engineer at Accio, an ML Researcher at Alibaba Cloud, and a Business Analyst at Alibaba Group, and I've independently designed and deployed 40+ full-stack products — AI assistants, study tools, travel platforms, real-time marketplaces, and productivity systems. I hold a U.S. patent for a foreign-language-learning application, and my NLP research was presented at an international conference and published across 10+ journals.
