Short Bio:

My research is aimed at understanding the molecular mechanisms governing cell adhesion and motility, in particular those involving white blood cell function in normal as well as in pathologic outcomes.

Circulating white blood cells represent the immune system’s front-line defense against infection. The successful and accurate targeting of white blood cells to inflamed tissues is facilitated by cell adhesion receptor proteins expressed on the surface of these cells. However, aberrant function of these receptor proteins and the cellular signals that regulate them can lead to diseases of the immune system, including leukemia, lymphoma and autoimmunity.

My laboratory is focused on understanding the differences in cellular signalling between healthy and diseased cells in order to explore and evaluate novel signalling targets for therapeutic intervention in blood diseases. We employ a multi-disciplinary approach that encompasses cell biology, protein biochemistry, molecular biology and immunology.
