Economic Evaluation & Impact Modeling
I use economic evaluation, decision modeling, and real-world evidence to assess the expected impact, cost, affordability, and value of interventions. My work compares alternative uses of limited resources, projects outcomes under different implementation and scale-up scenarios, and identifies the assumptions and uncertainties most likely to influence a decision. These analyses help policymakers, funders, and program leaders determine which interventions to adopt, adapt, scale, or evaluate further.
