I'm an 82-year-old retired grandfather with a broad range of interests.
For 31 years I was a scientist at the University of Pennsylvania School of Medicine. My research included light and electron microscopic examination of bone and cartilage.
I chronicled for the first time in living tissue:
1. the critical role of chondrocyte mitochondrial calcium during the primary calcification of epiphyseal plate and bone fracture cartilage, and,
2. in a bone fracture, the progressive transformation of endothelial cells and pericytes into mesenchymal cells and their subsequent development into chondrocytes.
