I find signals
in noise.
AI/ML engineer. I build systems that pull faint truths out of overwhelming data — from operating rooms to distant stars.
A planet's shadow in 144,000 light curves
NASA's TESS telescope stares at the sky and streams back noise — stellar flicker, instrument drift, cosmic junk. Somewhere in it, a star dims by a fraction of a percent: a planet passing in front. COSMOS hunts that dip.
Method
An end-to-end detection pipeline on consumer hardware: 15 orthogonal detectors — classical Box-Least-Squares transit search, the MOMENT time-series foundation model, and dedicated channels for single transits, exocomets and microlensing — swept across the TESS survey. Honest verdict included: candidates reported as candidates, nulls as nulls.
The crash, 4½ minutes before it happens
In an operating room, vital signs whisper before they scream. PulseGuard listens to the whisper — an early-warning system that flags intraoperative deterioration minutes before it becomes a crisis, without drowning clinicians in false alarms.
Method
Trained on VitalDB (5,170 real anesthesia cases, Seoul National University Hospital), externally validated on MOVER (UC Irvine) — two hospitals, two continents. Gradient-boosted models over routine monitor channels with conformal calibration; evaluated on a locked held-out test of 303,909 windows. Plus a live monitor streaming a FHIR feed with a calibrated 10-minute forecast cone.
23,954 papers. The gaps glow.
Science has white space — pairs of ideas that are obviously related, that almost nobody studies together. You can't see it reading one paper at a time. CosmoScope maps an entire field from above and makes the gaps visible.
Method
Four years of arXiv cosmology and instrumentation papers embedded with sentence-transformers, clustered with BERTopic into ~39 recognizable topics. A white-space engine compares semantic proximity against actual co-citation — where proximity far exceeds co-occurrence, that's a research gap, proposed with real papers cited on each side.
Machines that check their own work
A language model alone will confidently invent a number. So I build systems where models police each other — one plans, one works, one judges — and none is trusted alone.
Method
Cash Flow Runway Advisor: a Planner→Executor→Judge loop with hard guardrails (iteration, token, wall-clock caps) and full trace telemetry, streaming over FastAPI. Small Action Model: Qwen2.5-3B fine-tuned with QLoRA for tool-calling, evaluated BFCL-style on decision accuracy and hallucination rate.
