I received my Ph.D. in Physical Chemistry at the University of Wisconsin in 1987. I started my career at Cray Research in the early 90s as a computational chemist and later moved into the Environmental Sciences Group, where I optimized weather, ocean and climate models to run on parallel computing systems. I held a variety of positions at SGI and Cray that involved working with customers, applications engineers and product development teams to understand requirements for HPC and storage systems in the weather and climate enterprise.

In 2009, I left SGI to work as a computational scientist at the Oak Ridge Leadership Computing facility at Oak Ridge National Laboratory. In 2010, I moved to the National Renewable Energy Laboratory, where I supported the use of high performance computing in support the mission of the US Department of Energy's Office of Energy Efficiency and Renewable Energy.

I returned to the private sector in 2018 to lead Cray’s Earth Sciences segment. I enjoy bringing together people with different expertise, to connect the evolving uses of computing in the weather and climate enterprise with emerging hardware and software technologies.

In my free time, I enjoy human-powered sports, primarily cycling, mountaineering and Nordic skiing.
