## whoami

I build clinical AI that knows when it doesn't know. I'm a PhD student in Computer Science at UC Davis, working on trustworthy AI for healthcare — LLM evaluation, uncertainty calibration, and synthetic data.

I do this research with Prof. Vladimir Filkov in the AI for Health Initiative (AI4H), where I lead RadAnnotate — an LLM-powered framework for reliable radiology report annotation, combining entity-specific models, synthetic data, and confidence-based selective automation.

I care less about topping a benchmark and more about a model not confidently lying to a doctor at 2 a.m.
