Dr. Kaartinen’s research program aims to understand how protein crosslinking enzymes (transglutaminases; TGs), extracellular matrix components and matrix stiffness can regulate cell behavior, and how TG-mediated protein modifications can change protein function. Her particular protein of interest is the extracellular matrix protein fibronectin. From a disease perspective, her group is interested in understanding if alterations in fibronectin matrix is linked to the pathophysiology of osteoporosis and defects in energy metabolism and adipogenesis. Her group uses cell cultures and transgenic mice as models of human disease, as well as chemical biology, biochemistry and cell biology experimental approaches.

Dr. Kaartinen received her MSc in Organic Chemistry from University of Jyvaskyla (Finland) and Ph.D. in Biochemistry from the University of Kuopio (currently University of Eastern Finland) in 1999. She completed her postdoctoral training at McGill University and joined the Faculty of Dental Medicine and Faculty of Medicine at McGill in 2002.
