Biography

I am a lecturer in the Department of Computer Science, Trinity College Dublin. Within the larger Computer Architecture Group, I lead my own small research group of six postgraduate research students, and one postdoctoral researcher. Before coming to Trinity College Dublin, I studied for a doctorate in Computer Science at the Technische Universitaet in Vienna, on the topic of compiling for advanced instruction level parallel architectures, such as VLIW and EPIC machines. In 2001 I was awarded my doctoral degree with distinction (mit augezeichnetem Erfolg).
