She has worked with private insurers, providers, employers, government agencies, and researchers in the United States and other parts of the world. She is a frequent speaker at professional and academic conferences. Rong has done pioneering work in a number of areas, including state-based risk adjustment programs for the commercial markets and for the uninsured population, risk-based provider contracting and profiling, risk-adjusted episodes of care, and predictive models for a variety of business applications. She works with clients to implement analytic methodologies and tools into their business process, and in this capacity assists clients to develop business rules and operational guidance to ensure program operational success.
