RESEARCH TRAINEES: 20 in career, 3 current


Nutrition, protein metabolism and requirements, aging, sarcopenia, muscle health and function, insulin resistance, cancer cachexia, body composition, hyperinsulinemic clamp, stable isotope tracers. 

Research Activities

My research program has 3 central themes:

The role of dietary protein in age-related muscle and physical function loss: Data analysis from large cohorts of older adults and intervention trials to test protein supplements specifically tailored to improve muscle mass and function of frail older adults, patients with cancer and those undergoing surgery. 

Protein metabolism in aging and metabolic disorders such as cancer cachexia and type 2 diabetes: Studies involve administering glucose and amino acids labelled with stable isotopes for in vivo kinetic measurement under different feeding conditions.

Comprehensive metabolic phenotyping: Measuring body composition, nutritional status, dietary intake, functional capacity and insulin resistance (using the insulin clamp) allows to characterize metabolic and nutritional conditions and test the impact of interventions.
