Research interests:

The main research interests in our laboratory are to understand the cellular and molecular mechanisms underlying aging and anti-inflammatory steroid hormone glucocorticoid-induced bone loss and marrow fat accumulation, focusing on how aging and glucocorticoids regulate bone marrow mesenchymal stem cell (MSC) lineage commitment towards osteoblast and adipocyte differentiation pathways. The approaches used in our studies include cell and molecular biology, stem cell biology, and transgenic and conditional gene knockout animal models. The ultimate goal of our research is to develop new strategies preventing aging- and pharmacological agent-induced bone loss.

Current projects:

Inflammation and bone loss with aging. The major goal is to investigate how PPARg, via regulating fat and fat-generated factors, controls bone homeostasis and immune functions during aging process.
