Dr. Masters' work focuses on two alternative payment models funded by the Center for Medicare and Medicaid Innovation (CMMI). First, he leads payment operations for the Comprehensive Primary Care Plus (CPC+) model. The aim of the CPC+ project is to strengthen primary care through multipayer payment reform and care delivery transformation. His work includes payment policy design, claims-based payment calculation, quality control, management, and collaboration with stakeholders. Dr. Masters oversees a large team of people working on payment for the model.

Additionally, Dr. Masters works on the Maryland All-Payer Model (MDAP) evaluation. The aim of the MDAP model is to test whether an innovative new global budget model for hospitals in Maryland improves health care outcomes, improves quality, and reduces costs. In his role he uses advanced econometric modeling to determine the impact of the All-Payer intervention on specific beneficiary and hospital subgroups using Medicare claims data.

Previously Dr. Masters worked as a researcher on various health-related projects, including examining HIV self-testing strategies in sub-Saharan Africa and looking at costs associated with healthcare provision all over the world. His prior research has been a mix of primary collection activities for randomized controlled studies and health facility surveys, as well as secondary data analyses, predominantly from surveys.
