Bob Deri

Bob Deri's technical scope spans fields such as photonic devices, micro-fabrication, communications systems and interconnects, integrated electronics, hardware, large laser systems and microwave diagnostics. He has continuously demonstrated technical leadership, brings teams to success in efforts ranging from leading proposal teams for projects like UltraPERL and Visibuilding to his current role leading critical laser development at the National Ignition Facility.

Deri's technical accomplishments have been well-received in the technical community with his election as an IEEE fellow, receipt of three R&D 100 awards and 91 publications. He's also co-inventor on 24 patents, with 11 pending, in the optoelectronics and laser optics fields.

Before starting at the Lab in 1992, Deri worked at Belicore in the area of photonic devices where he researched and invented multiple devices. He left the Lab from 1999-2005, when he served as chief optical scientist at Terrawave. Upon returning to the Lab in 2005, he has served in several critical technical leadership roles. He currently serves as the chief technologist in NIF and Photon Science, leading a team designing large-diode-pumped solid state lasers.

"I'm extremely honored to have been selected for this award, and appreciate this recognition of my work," Deri said. "Any success I've had over the years has been due to the support and guidance of many colleagues, and to the opportunity to participate in important, challenging projects at LLNL, for which I am grateful."


Frank Graziani

Frank Graziani has spent 27 years at the Laboratory where he has advanced the science of the national weapons program, nurtured and developed new staff and has collaborated with technical staff at all levels, all labs, the National Nuclear Security Administration (NNSA) and the broader academic community.

Graziani has dedicated his career to the physics related to nuclear performance.

While his technical leadership clearly affects the achievement of LLNL and NNSA, Graziani also dedicates himself to recruiting and developing early-career staff members to enhance the future of both science and the Laboratory. His mentoring has contributed significantly to the technical success of others and provided the tools and encouragement necessary for those willing to accept difficult challenges.

"I am both honored and humbled at being selected as a Distinguished Member of the Technical Staff," Graziani said. "In the almost 30 years I have been at LLNL, I have had the privilege to work with and lead an extremely talented group of physicists, engineers, computer scientists and technicians. They have made me a better scientist.

"In many ways, I owe this honor to them. I am also grateful to my management for providing me with support and opportunities that allowed me to grow as a scientist. Being recognized as a DMTS for something I have been passionate about and I have had fun doing is truly rewarding. When I look at the other individuals who have received the DMTS, several of whom have been my mentors, I am humbled that I was considered for this honor."


Hye-Sook Park

Hye-Sook Park joined LLNL as a postdoc in 1987 and became a staff scientist in the Physics Directorate in 1989. In 2002, she joined the NIF and Photon Science Directorate where she began using ultra-intense lasers to generate bright high-energy X-ray sources and developed techniques to probe matter at extreme density and temperature on high-power, laser-driven experiments.

In a very short period, she became regarded as a world's authority in the use of petawatt-class laser to generate high-energy X-ray sources of radiographically probing dense matter with -psec resolution. The techniques she developed are now in use at essentially all high-power laser facilities around the world.

Her other experiments have broadened the reach of the field of plasma physics into regions deep in planetary interiors and aspects of extreme states of solid-state material dynamics. She also helped develop the Irvine-Michigan-Brookhaven detector to look for proton decay and neutrinos; detectors, hardware and software of the MACHO project to look for dark matter; detectors and software for the CLEMENTINE mission to map the lunar surface; the Gamma-Ray Optical Counterpart Search Experiment for observing gamma-ray bursts; and was a key member of the team that discovered the burst of neutrinos from Supernova 1987A.

"I am honored and I am humbled by this recognition," Park said. "LLNL is a unique place where so much cutting-edge science is carried out. I've been very fortunate to work on many interesting projects here at LLNL from astrophysics to plasma physics and material science. With support from management and my colleagues, I have enjoyed the privilege of discovering previously unseen physics. I am sure LLNL will continue supporting great science."


Rick Ryerson

Rick Ryerson's interests and impact span a broad swath of geoscience, ranging from local and global tectonics to experimental petrology and geochemistry, and from mineral and rock physics to nuclear waste management, geologic CO2 storage and hydraulic stimulation of hydrocarbon and geothermal reservoirs.

Ryerson's published works, even those from his early career, continue to be highly cited. His wok in trace and major element partitioning formed the basis for understanding the saturation behavior of phosphate minerals in magmas. In the 1990s, Ryerson and his colleagues began studying the partitioning of trace elements between minerals and aqueous fluids under mantle conditions. These were first-of-a-kind measurements that remain the standard for the field.

More recently, he has turned to the study of core formation in terrestrial planets. When hydraulic fracturing or "fracking" to access unconventional oil and gas reserves was a hot topic in the fossil fuel industry, Ryerson was tapped to lead a team to develop GEOS -- a dynamic computational rock mechanics and hydrologic tool -- that can model facture propagation, resulting seismic signals and pressure-driven fluid flow through a rock mass. The tool also is applicable to problems in geothermal energy, carbon sequestration, unconventional oil and gas reserves and nuclear explosion monitoring.

"It is extremely gratifying to be chosen to join this select group of Lab scientists and engineers," Ryerson said. "Over the years, I've been fortunate to work with a wonderful group of colleagues, postdocs and students. This is a good opportunity to thank them for sharing their expertise and enthusiasm."

Ten LLNL researchers were named Distinguished Members of Technical Staff (DMTS) in 2012 (affiliations are in parentheses):

  • Jim Candy (Engineering)
  • John Castor (Weapons and Complex Integration)
  • Jim Hammer (Weapons and Complex Integration)
  • Omar Hurricane (Weapons and Complex Integration)
  • Neil Joeck (Global Security)
  • Nino Landen (National Ignition Facility)
  • Ken Moody (Physical and Life Sciences)
  • Bruce Remington (National Ignition Facility)
  • Dmitri Ryutov (Physical and Life Sciences)
  • Tom Slezak (Computation)


Jim Candy

Jim Candy has more than 36 years at the Laboratory in signal and image processing, which has made fundamental impacts inside and outside the Laboratory, where he has been called one of LLNL's "natural resources." His work is a critical element in a wide range of Lab projects and disciplines. Jim's work at LLNL has spanned a broad variety of technical areas, programs, and work-for-others projects, bringing national and international recognition to himself and the Laboratory with his novel signal and imaging processing research and development.


John Castor

In his 30 years at the Laboratory, John Castor has made a name for himself inside and outside the weapons labs. His initial theoretical work in astrophysics on the theory of stellar pulsation led him to the study of non-local thermodynamics equilibrium processes in stellar atmospheres. His work on the theory of radiatively-driven stellar wind — the astrophysical work for which he is best known — allowed him to draw up a paper in 1975 that is widely considered one of the most influential papers in astrophysics of the 1970s and 1980s, with more than 1,000 citations. Castor joined the Laboratory in 1981 and he linked up with the secondary design physics division where he has been ever since. His efforts went from radiation transport techniques and applications in astrophysics to physical databases for the simulation codes to other studies such as the dynamics of missile flight. Recently, he has advised the NIF Ignition Campaign on material property questions.


Jim Hammer

Jim Hammer has been a physicist at the Laboratory since 1979, starting in the magnetic fusion area, then joining the Inertial Confinement Fusion Program in the early 1990s and continuing into A Program. He is recognized for the invention and demonstration of new fusion and high-energy-density concepts as well as groundbreaking science. Initially working on the Lab's spheromak experiment, he went on to come up with the idea that led to what is now known as "fast ignition." He also has worked on pulsed-power driven fast Z-pinches and the energy balance issue in the weapons program — he identified a previously unrecognized physical effect that plays a dominant role.


Omar Hurricane

Omar Hurricane's impact on the important core LLNL mission of Stockpile Stewardship has been well recognized as transformative. He has established himself as a leading authority in secondary design physics as well as high-energy-density plasma physics. In 2009, he won the E.O. Lawrence Award for national security and nonproliferation, one of the highlights of his 18-year LLNL career. He won the award for providing the dominant solution to a 60-year-old problem in weapons design that is euphemistically called "energy balance." The implication is that underground nuclear tests will no longer be required to establish this empirical parameter and the design uncertainty associated with this phenomenon has been significantly reduced.


Neil Joeck

Neil Joeck, a 25-year Lab veteran in Z Division and the Center for Global Security Research, has conducted career-long work on weapons of mass destruction in South Asia, a subject in which he is recognized as a world expert in the academic community, the U.S. government national security community, and South Asia political circles. Joeck's seminal work in 1995 and 1998 at Z Division, in 2001 and 2002 at the State Department, in 2005 at the National Security Council, and in 2010 as National Intelligence Officer for South Asia provided unique insights, which drove senior U.S. government officials to formulate and implement policies that helped to reduce the nuclear and terrorist threat in South Asia.


Nino Landen

Twenty-eight year Lab veteran Nino Landen has made outstanding experimental and analytical contributions to inertial fusion and high-energy-density plasma physics. He has demonstrated sustained innovation in x-ray based plasma experimental techniques and analysis. Landen's key areas of research have included short-pulse laser–plasma interaction, radiation transport experiments, and ignition tuning as part of the National Ignition Campaign.


Ken Moody

Ken Moody, a 26-year Laboratory veteran, joined the Heavy Element Group in 1985 and has been a critical member of the team to discover six new elements — 113 through 118. In addition, he has added more than 40 new isotopes to the chart of nuclides. Trained under Glenn Seaborg, Moody has dedicated his career to the scientific advancement of radio- and nuclear chemistry for the scientific and programmatic communities. In addition, Moody is one of the creators of the discipline of nuclear forensics, and applications of radiochemistry to national security and law enforcement problems.


Bruce Remington

Bruce Remington joined the Lab as a physics postdoc in 1986 and two years later he joined the laser program (now NIF) and has been there ever since. His achievements span three major areas of high-energy-density physics. He performed seminal experiments in inertial confinement fusion; led the creation and development of the High Energy Density Laboratory Astrophysics (HEDLA) project through scientific achievements and the mobilization of an international community; and pioneered the use of lasers to achieve ultrahigh pressure, ultrahigh-strain-rate (deformation) conditions in solid materials, also known as material dynamics at extreme pressure and strain rate.


Dmitri Ryutov

Dmitri Ryutov officially joined the Lab in 1994 but has closely collaborated with Lab physicists since the 1980s. He is recognized nationally and internationally for his contributions to fusion science and plasma physics research. During his decades-long research career in the United States and the former Soviet Union, he has made seminal contributions to magnetically confined fusion, space and astrophysical plasmas, and other applications of plasma physics and general physics. Ryutov's broad knowledge of general physics, combined with his talent for doing analytic calculations that are both relevant to and important for a given subject, has allowed him to identify and solve important problems in areas well outside of plasma physics.


Tom Slezak

Tom Slezak came to LLNL as a summer student in 1974, working part-time during the school year and full time during the summer. He joined the Lab as a full-time computer scientist in 1978, working for what was then called the Bio-Med Program. He eventually went on to work on the Human Genome Project, pioneering the use of what came to be called "bioinformatics" in DNA physical mapping, and was part of the team that built the Joint Genome Institute in Walnut Creek. In 1999, he was tasked to build a pathogen bioinformatics team that went on to build the BASIS system to provide wide-area monitoring for bioterrorism. His team also worked to create the nation's BioWatch system in early 2003.
