Hans’ research seeks to understand how to maximise the utilisation of computer systems in order to increase speed of computation, or reduce energy consumption. A central tenet of his research is to tease out key characteristics of applications, software and hardware and leverage these to develop bespoke algorithms and optimizations. His research focusses on runtime-system techniques, compilation and application-specific solutions. He has applied his research to scientific computing codes and data analytics problems.
