Research Focus

My research focuses on understanding pathophysiology of multifactorial musculoskeletal disorders. Bone has many unique and overreaching functions in the organism, including its role in locomotion, in calcium homeostasis and in housing hematopoietic bone marrow. Specific projects in my laboratory aim to 1) understand how bone cells, in particular bone resorbing osteoclasts, are affected in different disorders in order to identify novel pharmacological targets for diseases associated with bone loss; 2) establish the role of purinergic signaling in bone mechanobiology; 3) develop computational models linking bone mineralization, bone resorption and calcium homeostasis.
