Welcome to Dalhaimer Lab

Nanomedicine for Metabolic Diseases and Aging

Research Synopsis

We are interested in the roles that aging and obesity play in soft nanoparticle pharmacokinetics and pharmacodynamics. We work primarily with soft nanoparticles that are poly-ethylene-glycol and lipid-based. Our favorite cell is the macrophage. A larger part of our work is to understand how to modulate macrophage physiology using soft nanoparticles. These efforts include anti-inflammation and macrophage rejuvenation.
