Social Medicine
My research addresses public health challenges in cancer patients and aging populations. I leverage advanced computational methods, including machine learning and psychometric analysis, to enhance patient-centered care through patient-reported outcomes. I also study social determinants of aging, such as health behaviors, cognitive function, lifestyle, and insurance, to support successful aging and improve quality of life.
