Erika Parsons

Associate Professor, School of Science, Technology, Engineering & Mathematics, University of Washington, Bothell

Dr. Parsons received her Ph.D. in Computer Science from the University of Tennessee, Knoxville, working with the Innovative Computing Laboratory. At Microsoft (2008-2013), she worked as an SDET for the Developer Division (.NET Framework). After rediscovering her passion for teaching and academic work, she became faculty at Washington State University and Everett Community College in 2013, prior to joining UW Bothell.

At Microsoft, Dr. Parsons worked in software reliability and performance testing for quality assurance across features of the Common Language Runtime, and designed technical specifications for threading features of the product. In regards to teaching, her philosophy and goal is to prepare students to be independent and motivated learners, focused around being a team with the students, where everybody has responsibilities towards a goal, very much like in industry.

Dr. Parsons research work and interests have focused on high performance computing, applied machine learning and statistical data analysis. Her research efforts have recently geared towards the application machine learning algorithms for development of software tools for academic advising, in particular a recommendation system for student academic pathways.

Bronis R. de Supinski

Chief Technology Officer, Livermore Computing, Lawrence Livermore National Laboratory

Bronis R. de Supinski is the Chief Technology Officer (CTO) for Livermore Computing (LC) at Lawrence Livermore National Laboratory (LLNL). In this role, he is responsible for formulating LLNL's large-scale computing strategy and overseeing its implementation. His position requires frequent interaction with high performance computing (HPC) leaders and he oversees several collaborations with the HPC industry as well as academia.

Prior to becoming CTO for LC, Bronis led several research projects in LLNL's Center for Applied Scientific Computing (CASC). Most recently, he led the Exascale Computing Technologies (ExaCT) project and co-led the Advanced Simulation and Computing (ASC) program's Application Development Environment and Performance Team (ADEPT). ADEPT is responsible for the development environment, including compilers, tools and run time systems, on LLNL's large-scale systems. ExaCT explored several critical directions related to programming models, algorithms, performance, code correctness and resilience for future large scale systems. He currently continues his interests in these topics, particularly programming models, and serves as the Chair of the OpenMP Language Committee.

Bronis earned his Ph.D. in Computer Science from the University of Virginia in 1998, and he joined CASC in July 1998. In addition to his work with LLNL, Bronis is a Professor of Exascale Computing at Queen's University of Belfast and an Adjunct Associate Professor in the Department of Computer Science and Engineering at Texas A&M University. Throughout his career, Bronis has won several awards, including the prestigious Gordon Bell Prize in 2005 and 2006, and R&D 100s, including one for his leadership of a teamthat developed a novel scalable debugging tool. He is an IEEE Fellow.
