I am a dietitian and nutritional epidemiologist with extensive interdisciplinary research background from basic biology to epidemiology. My career goal is to leverage my diverse research skills in nutrition, dietetics, and epidemiology of aging to launch an independent academic career in “Precision Nutrition” aimed to optimize nutritional recommendations for older adults. My research emphasis is on the integration of omics (e.g., gut microbiome and metabolome) and non-omics (i.e., actual dietary intake) data to develop age-specific dietary recommendations, replacing the current one-size-fits-all approach, to promote healthy aging.
My contributions to the field of nutrition and aging began during my PhD training at McGill University, where I determined the relationships between dietary protein intake, body composition, and physical function in a cohort of community-dwelling older adults. I continued my training as an NIA T32 Post-Doctoral Scholar at University of Pittsburgh to leverage the expertise and resources at the Center for Aging and Population Health to better understand age-related biological changes and their potential to be targeted by nutritional interventions by adopting omics approaches. Currently, I am leading the Microbiome & Inflammaging Ancillary Study of Muscle, Mobility, and Aging (SOMMA) cohort.
