For more than 60 years, the Lawrence Livermore National Laboratory has applied science and technology to make the world a safer place. Livermore's defining responsibility is ensuring the safety, security and reliability of the nation' s nuclear deterrent. Yet LLNL's mission is broader than stockpile stewardship, as dangers ranging from nuclear proliferation and terrorism to energy shortages and climate change threaten national security and global stability. The Laboratory' s science and engineering are being applied to achieve breakthroughs for counter terrorism and nonproliferation, defense and intelligence, energy and environmental security.
His research spans computational and experimental materials science across fields, including solar energy, energy storage, and energy conversion. Much work has focused on the electronic, optical, and optoelectronic properties of semiconductors and nanostructures, emphasizing the relationships among defects, electronic structure, surface/interface effects, and device performance with a theme of enabling materials by design. He employs advanced predictive materials modeling methods in conjunction with advanced synthesis and characterization techniques. At Lawrence Livermore National Laboratory (LLNL), he leads a team of about a dozen computational materials scientists as the deputy group leader of the Quantum Simulations Group and oversees collaborations with experimental groups both internal and external to LLNL. He was a LLNL fellow and Scowcroft National Security fellow at LLNL, and a Hertz Fellow at Stanford where he received his doctorate. He was recently elected a young leader of The Minerals, Metals and Materials Society (TMS).
