Ph.D.
Identifying where lab-validated ML breaks in the field.

Based in Ghent until August 2026, returning to Taiwan thereafter.
Open to AS / RE roles, remote interviews available now.

I am currently working on synthetic data generation, extending my PhD research line to cross-environment ML transfer and explainable AI. Recently built a cost-efficient multi-agent LLM orchestration pipeline as PoC, and submitted a Google TPU Research Cloud proposal.

In 2025, I completed my Ph.D. at Ghent University-imec, and was previously a RA at Academia Sinica. Both my PhD and MSc research were conducted on real-world data, covering 5000+ hours of uncurated audio streams and extended video across multiple deployment sites.

My research focuses on building solutions at the mechanism-level while under real-world constraints. Recognition includes 12 peer-reviewed articles (7 journals, ICIP oral), 140+ citations, APICTA award, and Top 3% master’s graduate honor.
