Summary
Hello, I’m Chih-Hsien Liu, and I hold an M.S. in Space and Plasma Science from National Cheng Kung University.
Over the past two years I have worked as an R&D engineer at a biomedical company, focusing on cold-plasma interactions with human skin and leading experiment design and verification.
I also bridged NPI to manufacturing—including procurement, incoming inspection, and fixture/process definition—and improved pilot yield from 85% to 99.4%.
I am a listed inventor on two Taiwan patents.
I’m skilled at turning research outcomes into manufacturable designs and look forward to contributing to your team.
