Research interests

My main interest is in research related to vitamin D and bone metabolism and diseases.

Within the Longitudinal Aging Study Amsterdam, on ongoing Dutch population-base cohort study, I’m involved in studies related to prediction of vitamin D levels and potential effects associated with vitamin D deficiency. Also, we are currenlty performing a randomized controlled trial after the effects of vitamin D suppletion in patients with chronic obstructive pulmonary disease.

Currently, another research topic of my interest lies in osteoporosis and fracture risk. In the VU University Medical Center there is a special outpatient clinic since 2005 to identify patients with osteoporosis and othe reasons for a high fracture risk after presentation with a fracture, the “Osteoporosis and fracture clinic”. We will perform studies in the database of this clinic to examine several research questions such as the prevalence of secundary osteoporosis.
