Research in my laboratory seeks to discover the cause of disease in children with rare and previously undiagnosed genetic problems with their blood cells (hematopoietic system), including platelets, red and white blood cells that often present as immune defects or cancer. This new understanding will provide us with novel insights into the normal function of the hematopoietic system and help us better understand what's wrong with cancer cells leading eventually to new therapies.

The role of sumoylation in immune cell function: Sumoylation is a post-translational modification involving the addition of SUMO (small ubiquitin-like modifiers) groups that regulate protein function. This modification plays an important role in a wide range of cellular processes including protein stability, nuclear-cytosolic transport, apoptosis and cell cycle progression. We have identifed a number of rare disease patients with defects in sumoylation pathways that present with abnormal immune cell function, defective hematopoiesis and blood cancers. Studying their defects has provided novel insights into how sumoylation regulates immunity and hematopoiesis.Honours & Awards
