@jason-fries.bsky.social
Research scientist at Stanford University working on healthcare AI, foundation models, and data-centric AI. I focus on evaluating model reproducibility, training multimodal models with EHRs, and improving human-AI collaboration in medicine.
I’m recruiting postdocs who are excited to work with real clinical data and partner closely with clinicians.
If you’ll be at ML4H or the first day of NeurIPS, let’s connect!

My lab will focus on multimodal foundation models for healthcare, combining CS and clinical collaboration to understand and treat complex diseases like cancer.

Core interests: representation learning, synthetic data generation, longitudinal benchmarks, and agentic clinical AI.
