Research Directions:

            Molecular mechanisms and regulators of bone homeostasis

            Hormonal control and regulation of inflammation and metabolism.

 

Osteoporosis and Diabetes are common diseases with a high prevalence in the aging population. Chronic low grade inflammation accelerate insulin resistance and chronic high grade inflammation, such as arthritis have also profound impact on bone integrity. 

 

Our lab aims to unravel the endocrine control of cross-talk of immune and stromal cells during these pathologies and how resolution of inflammation can be fine tuned to alleviate disease and to allow repair of tissue integrity.
