Stephen Nicholas Swatman is a PhD student at the University of Amsterdam, working on computing challenges in the field of high-energy physics at the European Organization for Nuclear Research (CERN). Stephen studies the ways in which massively parallel compute architectures can be leveraged in complex, irregular scientific applications and aims to develop reproducible methods and models that can be used in a wide range of computational scientific domains. He is also interested into the applications of functional programming methods in high-performance computing in order to ensure correctness and performance.
