Dr. Antonio Trujillo is an Associate Professor in the Department of International Health with expertise in health economics, behavioral economics, and applied econometrics.

His main areas of interest include: i) Designing systems to identify individuals with high risk factors for chronic conditions; ii) Studying the use of economic incentives to motivate individuals with chronic conditions to engage in self-management; iii) Validating the role of clinical guidelines in reducing medical costs of chronic conditions; and iv) Studying the causal links between chronic conditions and labor force participation, income and retirement.

He has studied the role of intrinsic and extrinsic motivation on preventive behavior of patients with chronic conditions. His goal is to incorporate individual information on personality in the design of public health programs to increase treatment adherence among individuals with diabetes and hypertension. Currently, Antonio is exploring how an economic view of fairness can inform drug regulation to help promote price transparency and prevent price gouging.

Antonio is the director of the Master of Health Science (MHS) in Global Health Economics degree program. He teaches an advanced econometrics course on program impact evaluation using observational data and a course on behavioral economics and public health.
