Research Interests

Dr. Giachelli is internationally recognized for her work investigating the molecular mechanisms of vascular calcification and extracellular matrix control of cell function. Her studies have led to the discovery of key inducers and inhibitors that contribute to vascular calcification in the setting of chronic kidney disease, atherosclerosis, medial arterial calcification and medical devices. These discoveries are currently being translated to therapeutic strategies to block and/or treat inappropriate calcification in disease and biomaterials development.
