AI Research Scientist at Apodex · Singapore
I work on what goes into AI models and how to tell if they're any good.
I currently build pretraining data infrastructure at Apodex. Before that, I built Apodex’s deep-research agent harness from scratch, and at A*STAR I led data and evaluation for MERaLiON AudioLLM.
01 / Research into practice
01Apodex · May 2026–present
Built pretraining data infrastructure from scratch, evolving on-demand fetching into offline batch processing and integrating domain quality assessment with lightweight URL scoring to guide acquisition.
An acquisition pipeline covering raw HTML, PDFs, and other information-rich documents, with quality scoring to guide collection.
PRETRAINING DATA
02Apodex · May 2025–May 2026
Built the agent harness from scratch and led its core architecture as development grew to four or five contributors. Designed multi-source verification, parallel tool use, and multi-agent coordination.
A model and workbench for complex research, alongside the open-source FrontierAgent harness.
RESEARCH & TOOL USE
03I²R, A*STAR · 2023–2025
Led data preparation and evaluation, and co-led model training within a six-person team at A*STAR I²R.

02 / ESSAYS & NOTES
Submissions have grown from hundreds to tens of thousands. Conferences no longer disseminate or filter well, and certification is running on inertia. Strip those away and what remains is what a conference was at the start, a group of people meeting.
How research, career choices, a relationship, immigration, and chance all played a part in my decision to leave the United States for a postdoc in a country I had never visited.
