Duy is broadly interested in prescription drug policies and the impact of public policies on health and healthcare spending. In one line of work, he investigates the tradeoff between food and medication, and how prescription drug insurance reduces food insecurity among older adults. Another line of work focuses on the geographical variation in physicians' drug prescribing behavior and hospital staffing, and its implication on health and healthcare spending. He's also interested in how Medicare/Medicaid policies and pharmaceutical detailing reduce or exaggerate such geographical variation.
When not doing research, Duy enjoys hiking, backpacking, and traveling. His next trips include Chile, Peru, Cambodia, and Myanmar.
