Biographical Sketch

Dr. McKee is a full professor with a joint appointment in the Faculty of Dental Medicine and Oral Health Sciences, and Faculty of Medicine and Health Sciences. He received his B.Sc. and Ph.D. degrees from Â鶹AV in cell biology, and completed a postdoctoral fellowship in the Department of Orthopedic Surgery at Harvard University and The Children's Hospital in Boston. He then held academic appointments at the Forsyth Institute in Boston (1989), and at the University of Montreal (1990), after which he moved to Â鶹AV in 1998.

Dr. McKee’s research focuses on molecular determinants of biomineralization in bones and teeth, and in pathologic calcification as found in kidney stones and vascular calcification.

Of 239 total publications, Dr. McKee has 211 scientific articles published in peer-reviewed journals. He has a Google Scholar h-index of 83 with >30,100 total citations.

Research or Clinical Activities

McKee's research focuses on mineralization of extracellular matrices in bones and teeth, in mineralization pathologies, and in other biomineralizing systems such as inner-ear otoconia and eggshells. We are investigating the role of mineral-binding small biomolecules and proteins – most notably a protein called osteopontin – and the enzymes that modify these biomolecules to influence their mineralization-regulating activities. Our studies on pathologic mineralization include work on rare bone diseases where skeletal and dental mineralization is defective (osteomalacia / odontomalacia), and bones and teeth are soft and deform. We also investigate the actions of regulatory molecules where debilitating mineral deposition occurs in soft tissues such as in the kidney (urolithiasis, kidney stones), in blood vessels (vascular calcification), and in tendon and ligament insertions (entheses). In other recent work, based on findings describing underlying mechanisms guiding mineralization, we have recently shown how chiral amino acids can be used to produce synthetic, helical chiral suprastructures of calcium carbonate mineral.
