Research Focus

My research focuses on the role of calcium-regulating hormones in health and disease. My laboratory aims to elucidate how 1,25-dihydroxyvitamin D3, the active form of vitamin D, influences cell growth and differentiation in the skeleton and in cancer cells, and to elaborate new therapeutic strategies with vitamin D derivatives in osteoporosis and cancer. Another major focus of my research activities has been to establish the role of parathyroid hormone-related protein (PTHrP) in tumour initiation, growth and metastasis. This work has led to the development of a novel targeted therapy against breast cancer using monoclonal antibodies raised against PTHrP.
