Computer Scientist

I help model the physics of the world’s largest laser, set up experiments, and resolve equipment protection issues. I work with the top talent in several science disciplines and learn new physics and code development tools nearly every day. Most importantly, my work is helping scientists better understand material models and laser propagation issues, which will ultimately lead to improved clean-energy resources for humankind. 

Outside of work, I do Pilates almost every day and raise my two daughters who have entered the “tween” years.

I help scientists understand how the universe and the world work by discovering efficient theories facilitating the expression of complex physics, engineering, and social interactions as extremely large systems of equations. Mostly, I devise algorithms. I’m two-thirds math geek and one-third computer geek, but still 100% geek. LLNL has some of the most challenging and important problems to solve. We also have some of the most sophisticated tools in existence to solve them, and when we need some whizbang tool that doesn’t exist, we invent it.

I picked up a Sport Pilot license in 2011, flying a Champ, and am working toward a Private Pilot-Glider license, flying a Grob.

I find new ways to make simulations run fast on millions of processors at once. LLNL has one of the most vibrant HPC environments in the world. We have the world’s largest machines, the most sophisticated simulation codes, and world-renowned physicists all in one place. I learn something new every day.

I’ve taken up climbing since moving to the Bay Area from the East Coast in 2008.

I research and develop software for a distributed, parallel visualization and graphical analysis tool, called VisIt, which processes data defined on two- and three-dimensional (2D/3D) meshes. This software is used world-wide for scientific visualization and runs on some of the most advanced high performance computing (HPC) systems to include LLNL’s own state-of-the-art HPC environment.
 
I’ve also been afforded the opportunity to work on my PhD at the University of California, Davis through the Lab’s tuition-free, on-site degree program. LLNL’s alternative work schedule (AWS) program allows me to schedule days off during the work week to attend classes and stay on top of my studies. In my free time I enjoy doing home renovation projects, mobile programming, and occasionally training for a local half-marathon.
