Systems Engineering at LLNL


Contextualizing Decisions and Technologies

Our systems engineering covers many areas, from sensor development to space science engineering. Using advanced modeling tools plus optimization capabilities and uncertainty quantification, systems engineering strives to quantify and elucidate decision-making and to hone new technologies within the context of the systems they will impact.

Systems engineering at LLNL works in collaboration with other national laboratories, production agencies, and the Department of Defense to survey the active stockpile to assess safety, reliability, and performance and to create simulation tools and execute tests to modernize the stockpile of the future.

In addition to weapons systems engineering, this area runs the gamut from planetary exploration to high altitude sensors to studying greenhouse gases to space defense—LLNL Engineering is at the forefront of the final frontier.
