Experiences & Accomplishments
Johns Hopkins Bloomberg School of Public Health
My research focuses on 1) identifying policies to better align pharmaceutical prices and value and 2) the development of methods to better incorporate ethical considerations into value assessment and decision science. To advance these research goals, I pursue research into health technology assessment, multi-criteria decision analysis, tools of economic evaluation (e.g., cost-effectiveness analysis), and US and international health and pharmaceutical policy. In this work, I apply both empirical research methods and normative analysis. Finally, I am a committed educator and recently developed and taught an undergraduate course on ethical issues in health priority-setting. In the past, I have taught biomedical ethics at Dong-a University in Busan, South Korea. Other areas of interest have included the ethics of surveillance and influence in health, health systems governance and accountability, and the relationship between civil unrest and public health.

I work primarily with the Johns Hopkins Drug Access and Affordability Initiative and am affiliate faculty in the Berman Institute of Bioethics.
