Andrada Tomoaia-Cotisel

Policy Researcher and Professor of Policy Analysis, Pardee RAND Graduate School


Andrada Tomoaia-Cotisel is a policy researcher at RAND and a professor at Pardee RAND Graduate School. She specializes in developing and applying mixed methods approaches to explore issues of complexity and impacts across sectors of health systems. She has led formative and summative evaluations using thematic analysis, cluster analysis, and statistical outcomes analyses; as well as system dynamics modeling (diagrams and simulation). Her recent work has revealed the importance of feedback processes and causal relationships among program facilitators and barriers. She is an expert in capturing these relationships from qualitative data and literature, developing simulation models, and using infographics and visualizations to communicate understanding. 

Her work currently focuses on: (1) understanding the journeys of learning health systems to develop a self-assessment tool that would inform their ongoing journeys and (2) developing national medical workforce projections matching historical data and including physicians, PAs and NPs. In both projects, she focuses on causal mechanisms, context and policies as they influence trajectories over time – describing the past and projecting into the future.

Her recent work focused on: NICU quality improvement, primary care innovation, integration of behavioral health into primary care, and out of hospital cardiac arrest; studying service delivery, implementation and outcomes, the influence of context and variation.  She has also worked with the CDC and WHO to disseminate systems thinking methods for health research.

She earned her Ph.D. in health services research and policy from the London School of Hygiene and Tropical Medicine.
