One of Sal Baxamusa’s favorite things about working at Lawrence Livermore is the opportunity to learn new things on a regular basis. “Every day, I’m learning something new, often something that nobody ever knew before,” he says. As a chemical engineer in LLNL’s Materials Science Division as well as a deputy program manager for target fabrication at the National Ignition Facility, Sal develops devices, materials and materials-processing technologies primarily for applications that require engineered interfaces or thin films.
Sal’s work focuses largely on understanding how different systems change over time as they interact with their environment, as well as manufacturing, fabrication and synthesis steps to prevent or control those changes. He is especially proud of is his work on a team that developed a method to fabricate ultra-thin, tough, free-standing polymer sheets — a project completed in only a matter of weeks. “Our work was a lesson that developing subject matter expertise over the course of years can lead to ultra-productive bursts of scientific work,” he says.
Outside of work, Sal describes himself as a “run-of-the-mill, nerdy suburban dad” who enjoys reading science fiction, listening to music, watching baseball and hanging out with his family.
Sal received his Ph.D. in chemical engineering from the Massachusetts Institute of Technology and his B.S. in chemical engineering from the University of California at Berkeley.

Our Latest News
Our Current Projects
Our multidisciplinary teams collaborate with academic colleagues and industry partners to develop breakthroughs vital to national security and, often, that benefit commercial applications.
As our missions take us into new environments, we leverage LLNL’s computational capabilities to discover and design high-performance alloys with enhanced properties and performance under extreme conditions. We create new feedstock materials and additive manufacturing techniques that enable us to synthesize complex structures that are lightweight, corrosion-resistant and radiation tolerant. We also develop customized alloys that incorporate low-value rare earth elements, so we can produce components that are less susceptible to supply chain disruptions associated with critical materials.
Leveraging the power of 3D printing, we create materials whose properties are not fixed after fabrication, but instead react to environmental stimuli in real time. For example, changes in temperature, chemical environment, or variations in electromagnetic fields may cause a structure to bend or swell as it avoids breakage or absorbs a liquid. Most recently, LLNL researchers have developed a liquid crystal elastomer — a soft material that morphs in response to light, which has implications for future soft robotics that can do work where rigid materials cannot.
We explore ways to stop material degradation before it starts—research that’s critical to ensuring the long-term performance of our nation’s nuclear stockpile and the resilience of our energy infrastructure. It’s also relevant to commercial applications, including aircraft and advanced batteries. Our materials science experts leverage LLNL’s supercomputers and machine learning tools to better predict factors that initiate corrosion, especially for new types of additively manufactured material. They integrate experimental data into their simulations to capture complex corrosion processes and better understand how a material will perform at scale, in relevant conditions, over its service lifetime.
