Research Interests

Prof. Georgiadis’ research interests are driven by open questions related to how the human brain and muscle change with age, and involve the use of non-invasive techniques like Magnetic Resonance Imaging to probe the human central nervous system and skeletal muscle. His current research activities involve three projects:

1. Intramyocellular Biotransport and Muscle Quality in Aging and Obesity
2. Computational Imaging of the Aging Cerebral Microvasculature
3. Multiscale Mechanical Models for the Aging Brain
