He conducted his PhD in Biochemistry in UCD, followed by postdoctoral cell biology research in Simon Fraser University (Canada). His research focusses on the primary cilium, and specifically, the role of protein and membrane trafficking pathways in cilium formation, function and disease mechanisms. Much of his work is conducted using the C. elegans nematode model, combining genetics and in vivo imaging approaches such as live intracellular transport assays and super resolution microscopy.
