Dr. Alexey Pshezhetsky graduated from the Department of Chemistry, Moscow State University in 1985. In 1989 he obtained Ph.D. degree in chemical kinetics and catalysis from the same university. In 1989-1992 he was a researcher in Moscow State University and Moscow Institute of Medical and Biological Chemistry studying genetic diseases of children caused by the inherited deficiencies of lysosomal enzymes. In 1993 Dr. Pshezhetsky joined Departments of Pediatrics and Biochemistry, University of Montreal where he was subsequently promoted to professor. He is also affiliated with the Department of Anatomy and Cell Biology at McGill University. Since 1998 he is a scientific director of Medical genetics diagnostic laboratory and a director of a Laboratory of lysosomal biology at Ste-Justine Hospital Research Center. The research of Dr. Pshezhetsky has been acknowledged by multiple national and international agencies including the Canadian Institutes of Health Research, Canadian Foundation for Innovation, Genome Canada, Genome Quebec, March of Dimes Foundation, Vaincre les Maladies Lysosomales and others. Dr. Pshezhetsky received many career awards and fellowships including a National Investigator Award from FRSQ and an Award of Excellence in Pediatric Research from the Foundation for the Research in Children’s Disorders. The current research interests of Dr. Pshezhetsky include molecular basis of lysosomal and other inherited metabolic disorders, glycobiology, proteomics and functional genomics of the cell.
