Peter Lyons is Professor of Biology at Andrews University, specializing in biochemistry with research focus on metallocarboxypeptidases and their roles in human health/disease. Earned Ph.D. from Dalhousie University and conducted postdoctoral research at Albert Einstein College of Medicine. Research integrates: Biochemical analysis of proteolytic enzymes Zebrafish developmental models Cell biology approaches Investigates how metallocarboxypeptidases regulate protein/peptide activity through proteolysis, particularly examining: Functional consequences of enzyme mutations Evolutionary adaptations in enzyme families Pathways from prediabetes to diabetes Funded by NSERC, NIH, and Grass Foundation. Develops accessible laboratory modules for undergraduate education, including enzyme isolation protocols.
