Personal Statement:

My research interests are in regenerative medicine, as described below. I also serve as the Co-Director of the San Antonio Nathan Shock Center and as Co-Leader of the Research Career Development Core of the San Antonio Older Americans Independence Center (Pepper Center). Recently, I co-edited the 9th edition of the Handbook of the Biology of Aging together with Dr. Nicolas Musi, director of the Barshop Institute.

Research

Regenerative Medicine – Stem Cell Delivery. Our research focuses on modes of stem cell delivery to exert a therapeutic effect in age-related diseases. Most recently the lab’s research has concerned intranasal delivery of mesenchymal stem cells to the brain.

“Human mesenchymal stem cells crossing the cribriform plate into the brain in a mouse. Human stem cells were labeled with quantum dots (red) and administered intranasally. Two hours later they are seen crossing the cribriform plate in this image (arrows). In (b) nuclei have been stained green. (c) is an overlay of (a) and (b). cp = cribriform plate; fo = fila olfactoria; lp = lamina propria; oe = olfactory epithelium; onl = olfactory nerve layer”
