Philip Roth joined the Scientific Computing group in November 2018. He is part of a team that analyzes and improves the performance of applications targeting the current and future computing systems deployed in the Oak Ridge Leadership Computing Facility. Prior to joining the Scientific Computing group, Roth researched performance analysis tools and techniques, and did application performance engineering, for over 14 years within the ORNL Future Technologies group. Before that, he researched scalable and automated performance diagnosis techniques at both the University of Wisconsin-Madison and University of Illinois at Urbana-Champaign. Between his two stints in graduate school, he worked as a software developer for a startup company in west-central Wisconsin that sought to produce high-end servers incorporating supercomputing design and expertise.
