Ashis Das is a physician-epidemiologist with over 20 years of experience in real-world data (RWD) and health economics and outcomes research (HEOR). For more than a decade, he built AI-enabled decision-support and predictive modeling systems on claims, EHR, and registry data—well before "agentic AI" became a category. He now leads AI initiatives at Komodo Health, including Marmot, the company's agentic real-world evidence platform, with a focus on validation: ensuring AI-generated evidence is reproducible, unbiased, and defensible, not just fast. His work spans disease staging, cost-of-care analysis, and comparative device studies across pharma and biotech engagements, where getting the underlying data right is the prerequisite for trusting any AI layer built on top of it.
Most AI isn't built for research. It's built for chat, for dashboards, for demos. In HEOR, that gap shows up fast. Fragmented data. Opaque models. Manual workflows that break the moment a regulator or peer reviewer asks how an answer was produced.
This session outlines a different approach: healthcare-native AI designed specifically for rigorous, defensible evidence. Three pieces, working together. A Healthcare Map of 60+ curated sources with validated representativeness across payers, regions, and care settings. A research-specific architecture with unified visit consolidation, 95%+ cost fill, and continuous enrollment, built so methodology holds up under scrutiny. And an AI engine with visible code generation, stepwise validation, and explicit articulation of every limitation.
The result is RWE that's faster, scalable, and trusted. Cohort identification compressed from hours to minutes. Descriptive statistics that used to take months. Industry standard R-package integration for inferential methods like propensity score matching, survival modeling, and weighted analyses, all version-controlled and replicable. Ready for the moments that matter most: market access discussions, internal strategic decision making, peer reviewed publications, and guideline directed medical therapy for real patients.
