Alfred Sattelberger (Argonne Associate Laboratory Director) affirms that Martin is "one of the key reasons that Los Alamos is regarded as the top chemistry organization in the entire DOE complex."

Amit Misra has had a tremendous impact on the field of structural materials. He has pioneered the development of metal nanostructured multilayers for a range of structural applications, and he has defined this class of materials as a critical platform for understanding the underlying principles that drive new discoveries. His work on plastic flow stability provided theinsight into the development of damage-tolerant nanocomposites that is being explored in the Energy Frontier Research Center at Materials and Irradiation Extremes, for which he serves as codirector. Misra has also explored thermal and irradiation stability of nanolayered materials. Through this work, he discovered that interfaces can trap and annihilate radiation-induced point defects, which has significant implications for the design of new radiationtolerant materials. Another important discovery made by Amit was his research on nanometer-spaced preferentially aligned twins in sputter-deposited face-centered cubic metals is expected to lead to the development of high tensile strength electrical conductors. His cumulative work earned him a 2008 Lab Fellows Prize for Research and has been published in more than 220 peer-reviewed journal articles (in excess of 2,400 citations) and five book chapters.


William (Bill) Louis is one of the world leaders in neutrino physics and has led the Los Alamos accelerator-based neutrino experiments since the early 1990s. In particular, Louis led the Large Scintillation Neutrino Detector (LSND) collaboration, the most successful neutrino experiment to be carried out at the Los Alamos Neutron Science Center, and he is co-leader of the MiniBooNE experiment initiated in 1999 at Fermi National Accelerator Laboratory. The results from LSND were both striking and anomalous; if confirmed definitively, they would require a major revision to the Standard Model of the universe, or at a minimum a revision to include the existence of “light, sterile neutrinos.” Recent results from MiniBooNE did not observe all the expected results from LSND. However, they do show an unexpected low-energy behavior of the spectrum of neutrino events that also would require re-thinking aspects of neutrinos and the Standard Model. Should these combined results turn out to be correct, many in the field will consider the discoveries to be historic. Louis’s publication record of more than 70 papers includes 22 with more than 50 citations, and three of them having more than 500 citations. He is a Fellow of the American Physical Society.

John Sarrao discovered the first plutonium-based superconductor, revolutionizing the field of actinide materials research.

His work has generated great excitement in the materials physics community, and research efforts around the world have been redirected to build upon Sarrao’s discoveries. His work has been cited more than 6,000 times and he was distinguished as the Lab’s most published author every year between 2001 and 2007. Sarrao is a Fellow of the American Physical Society, and the American Association for the Advancement of Science. He received the Lab Fellows Prize for Outstanding Research in 2004. Sarrao now brings his exceptional creativity and scientific insight to bear as the lead for the Laboratory’s materials-centric future signature facility, MaRIE (Materials-Radiation Interactions in Extremes), which is intended to revolutionize the understanding of materials in extreme environments and conditions.

Dipen Sinha is known for his expertise over a wide range of disciplines, including low-temperature physics, ultra high-speed measurements, infrared detector arrays, organic thin films, biomedical instrumentation, acoustics, and geophysics. One of his major accomplishments is the development, refinement and exploitation of Swept Frequency Acoustic Interferometry (SFAI), a technique for noninvasive characterization of fluids. Applying theory and novel instrumentation, Sinha extended this technique to allow noninvasive interrogation of fluids in sealed containers. His work has enabled wide application of SFAI to national security missions, including chemical and biological warfare treaty verification, and rapid identification of chemical and biological warfare agents inside sealed munitions. In 2005, Scientific American identified his bioweapons detection work as one of the top five inventions in acoustics. Applying additional creative and innovative ideas to nonlinear acoustics, his work is being applied to remote landmine and concealed weapons detection. In the fields of medicine and biology Sinha’s work has led to development of the Acoustic Flow Cytometer, which recently was licensed by a pharmaceutical company for detection of and discrimination between benign and cancerous breast tumors. He has won three R&D 100 awards, the Lab Distinguished Licensing Award, and twice received the Distinguished Patent Award.

Giday Woldegabriel is co-leader of an international research team responsible for discovering the oldest nearly intact skeleton of Ardipithecus Ramidus, who lived 4.4 million years ago. “Ardi” is the earliest skeleton known from the human branch of the primate family tree; its discovery provides new insights into how hominids may have emerged from an ancestral ape. The discovery and associated research were named Science magazine’s Breakthrough of the Year for 2009 and Time magazine’s number one science story of 2009. Woldegabriels’ key scientific contribution to this discovery is the geologic interpretation and geochronologic dating of the strata in which the fossils were found. Additionally, he was instrumental in facilitating the entire field investigation that enabled the discoveries and interpretation of the flora and fauna of the time period in which the early hominid existed. Woldegabriel’s most recent work includes invaluable geology-related contributions to multiple programs. His work has helped track migration of radionuclides in groundwater, geothermal energy exploration, and carbon management of fossil fuel combustion byproducts. His work has led to substantially increased understanding of the complex volcanic structure and evolution of the Pajarito Plateau and the Nevada Test Site. Woldegabriel received the Fellows Prize for Research in 2001, and has nearly 45 publications and about 1,500 citations to his credit.
