About
I'm an AI research scientist at Apodex in Singapore, where I'm the main contributor to our pretraining data acquisition pipeline. Before that, I built Apodex's deep-research agent harness and its evaluation framework.
Earlier, at A*STAR, I was a lead contributor to MERaLiON, Singapore's national audio LLM, and built the AudioBench and SeaEval benchmarks. I received my Ph.D. from USC in 2021.

Selected work
03Pretraining data infrastructure
Apodex · 2026 — Now
Main contributor to a frontier-scale pretraining data acquisition pipeline built from scratch: a high-concurrency crawling cluster with its deduplication and database layers, plus the crawl prioritization and data quality assessment that decide what is crawled for training.

Deep-research agents and their evaluation
Apodex · 2025 — 2026
Built the deep-research agent harness behind the open-source MiroThinker models and the Apodex models, including multi-source verification of research claims. Built the agent evaluation framework, with contamination checks, for benchmarks such as BrowseComp, GAIA, and HLE.

Benchmarks for language and audio models
A*STAR · NUS · 2021 — 2025
Benchmarks and evaluation methods that others build on: AudioBench for audio LLMs (280+ citations), SeaEval for cross-lingual consistency and cultural reasoning (100+ citations), and FacEval for the faithfulness of dialogue summaries.

04- Full Circle: Academic Conferences Will Go Back to Being Insider Gatherings2026-10Submissions 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.
