  • Although the U.S. healthcare system is characterized by providing the highest quality of care for some segments of the population, health care in the U.S. is inequitable, inefficient, and wasteful. In my research, I focus on investigating the causes of healthcare and health outcomes disparities, the causes of inefficiencies and waste, and strategies to eliminate these disparities. I also investigate the cost and cost-effectiveness of healthcare interventions.

    What prompted you to pursue your field?

    Medical and public health knowledge have improved drastically over the past decades with major advances in both disciplines. It is well known that the U.S. healthcare system provides the highest quality of care for some segments of its population, but healthcare in the U.S. is inequitable, inefficient, and wasteful. A strong research agenda is needed to investigate the causes of disparities and inefficiencies in the U.S. healthcare system and strategies to eliminate them.

    What's it like to teach at Parkinson?

    Students in our programs have diverse backgrounds in terms of fields of study and work experiences, which enhances mutual learning and engaging communication in educational settings.

    Why is this area of study important at this point in time?

    U.S. healthcare expenditures are on the rise. In 2019 we spent about 18% of our Gross Domestic Product (GDP) on healthcare as care in the U.S. continues to be inequitable, inefficient and wasteful. Disparities in healthcare access and health outcomes by race, ethnicity, socioeconomic status, among other factors are well documented. A recent article published in JAMA (October 2019) estimated that a conservative 25% of the U.S. healthcare spending is waste. Much work in terms of researching and advocating for effective health policies and interventions is needed.
