Science and engineering for investigating and interpreting the chemical properties, reactivity, synthesis and applications of energetic, optical, nuclear and multifunctional materials in support of our national-security missions.
The Chemical Sciences Division (CSD) conducts R&D at the intersection of chemical and nuclear science in support of LLNL's programmatic missions. CSD personnel provide expertise in organic/inorganic synthetic, analytical, computational, nuclear, environmental radiochemistry, and isotope geochemistry, as well as engineering and physics, to solve problems in stockpile stewardship and other national security programs such as forensics, nonproliferation, and counter-terrorism. CSD has world-class capabilities in energetic and advanced, multifunctional materials creation and characterization, nuclear chemistry and engineering, radiation detection and nuclear measurements, chemical and nuclear forensic science, and environmental radiochemistry, and isotope geochemistry.

Employee Highlight: Dawn Shaughnessy [bio]
Livermore Laboratory was one of Dawn Shaughnessy"s top choices for employment after finishing her postdoctoral fellowship at Lawrence Berkeley National Laboratory. Dawn, who earned her Ph.D. in nuclear chemistry from University of California, Berkeley, saw Livermore as a place where she could apply her expertise in nuclear and radiochemistry to projects relevant to national security while still performing basic research in heavy elements. As a staff chemist in the Stockpile Radiochemistry group, Dawn works on improving the understanding of underground test data as well as chemical and data analysis methods for nuclear event attribution.
She is also principal investigator of the Heavy Element Group, which has been responsible for the discovery of five new elements, most recently element 118 in 2006. This group's newest projects include rapid radiochemical separations of transactinides for exploring their fundamental chemical properties. Dawn recently received an Award of Excellence from the National Nuclear Security Administration's Defense Programs as part of a team that successfully reconstituted and exercised the capability to drill back into an underground test and provide diagnostic information from the samples.
