Research

Current Research:

My research concentrates on understanding the relationships among factors that influence dietary intake, and on the subsequent impact on nutritional status, morbidity and mortality outcomes, particularly among older adults. I use my expertise in nutritional epidemiology, dietary assessment, data analysis, and program evaluation to conduct this research, which involves analyzing large datasets and applying information acquired to implement and evaluate programs to improve people’s health. The ultimate impact of my research is to improve the quality of life of older adults leading to better health, in part, through providing knowledge needed for the development of public health policies that maximize health benefits while minimizing expenditure by both individuals and the country.
