Applied Scientist

I’m an Applied Scientist at Amazon where I build and evaluate LLM‑driven agent systems for shopping workflows. Before that, I worked as Research Engineer at FoundationEGI on automation for manufacturing design.

I have completed my Ph.D study at the University of Pennsylvania, where I was advised by Chenfanfu Jiang with the focus on physically-based simulation, numerical optimization.

News

  • July 2025I joined Amazon as Applied Scientist working on the evaluation system for Buy for Me, try it out!
  • Dec 2024I successfully defended my Ph.D. dissertation, completing my doctoral studies at the University of Pennsylvania.
  • Feb 2024I joined FoundationEGI as Research Engineer and working on the automation for manufacturing design, check our demo and see how it works!
