Livermore's talented staff is its key asset. The Laboratory’s many scientists, engineers, and support staff bring their knowledge, expertise, and experience to bear on the difficult challenges of its national security mission. They do so with an extreme curiosity, and a drive to uncover knowledge and better understand how things work. Here are some examples of Livermore’s gifted staff, and their work.

 

Studies how rocks fracture for energy security

Understanding the behavior of energy in the subsurface—how rocks fracture, how energy travels through the solid earth, and what its signature can tell scientists—is the key to several of Livermore’s security missions.

Advances high-energy-density science

High-energy-density science (HED) is an integral component of the Laboratory’s national security mission. As director of Livermore’s High Energy Density Science Center, physicist Frank Graziani works to foster academic collaborations in HED research, which often relies on Livermore’s National Ignition Facility, the world’s most energetic laser.

Performs research on climate simulation

Dean Williams conducts research on climate simulation using high-performance computing. He leads projects that have transformed how climate scientists organize, analyze, and share climate data, including the Earth System Grid Federation, the Ultrascale Visualization Climate Data Analysis Tool, and the International Climate Network Working Group.

Advances cybersecurity technologies

 

Celeste Matarazzo leads a project in cybersecurity situational awareness designed to address the national security threats to networks and information technology, and founded the Laboratory’s Cyber Defenders summer internship program for undergraduates, graduates, and others to train future cybersecurity experts.

Revolutionizes rocket engine designs with supercomputer simulations

Using high-performance computing, Greg Burton directs work to develop lower-cost rocket engines and space-launch vehicles for national security and scientific exploration. Virtual design, prototyping, and testing of these components and systems helps provide cost-effective access to space.

Protects our borders with next-generation radiation detectors

Livermore helps protect our borders by developing technology to detect the entry of illicit special nuclear materials (uranium and plutonium isotopes). Rebecca Nikolic recently led a team that developed miniaturized solid-state neutron detectors that are far more efficient and compact than existing devices.

Develops 3D printing techniques for manufacturing human-like tissues

Monica Moya is developing three-dimensional printing techniques for manufacturing vascularized tissue (containing blood vessels) using bioink—a fluid with biological components. Researchers can use these tissues to study exposures to chemical and biological agents, and assess medical treatments.

Conducts nuclear fusion experiments

At the National Ignition Facility, Tammy Ma leads experiments aimed at achieving fusion ignition by using it’s 192 laser beams to compress fuel capsules containing isotopes of hydrogen in a process called inertial confinement fusion. These experiments are laying the groundwork to demonstrate fusion's feasibility as a clean source of energy.

Transforms U.S. manufacturing with 3D printing

Lawrence Livermore has been at the forefront of developing revolutionary new methods to make materials and parts faster, cheaper, lighter, and with entirely new properties.
