Design and evaluate information access + reasoning strategies across RAG, agents, and classic ML: chunking, embedding models, hybrid search, metadata filtering, structured retrieval, tool use, and multi-step workflows
Prototype GenAI workflows (including agentic systems) that map and reason over compliance objects (controls ↔ risks ↔ requirements)
Explore ML + probabilistic approaches where GenAI is not the best fit: classifiers, ranking models, graph/link prediction, calibration, and weak supervision
Build and maintain evaluation frameworks: golden datasets, automated quality metrics, regression detection
Implement and tune ranking/reranking systems: cross-encoders, LLM-based rerankers, learning-to-rank, custom scoring functions
Run experiments to validate hypotheses and quantify improvements before production rollout
Debug failure modes and build error taxonomies across retrieval, reasoning, and generation
Collaborate with AI and Software Engineers to hand off validated approaches for productionization
Stay current on applied research in RAG, agents, LLM evaluation, and relevance modeling; bring innovations into the product
