Design and build predictive ML models that identify and prioritize patients and healthcare providers most relevant to specific medicines, brands, and therapeutic areas, in order to predict clinically and commercially significant outcomes such as patient-identification and therapy-tolerance model products. Design and build Agentic AI systems built on large and small language models (LLMs and SLMs) that autonomously carry out multi-step commercial-engagement and analytics workflows, together with engineering platforms required to operate, evaluate, and measure those systems reliably and in compliance with healthcare-data regulations. Partner with engineering and infrastructure leaders, external data-science and platform-engineering vendor teams, and commercial business stakeholders to define what each system must do and how its quality and business value are measured. Shape and develop AI/ML and data science initiatives including individual modeling programs (such as the hematology/oncology patient-identification and therapy-tolerance modeling programs) and enterprise AI-platform initiatives (such as the agent-evaluation framework, the conversational-analytics platform, and the Agent observability platform), spanning the full range from early problem framing and architecture through hands-on implementation and production deployment.
