DOE Announces New Assignments in ASCR Program

Last week Michael Strayer, Associate Director of the Advanced Scientific Computing Research (ASCR) program in the DOE Office of Science, announced that Fred Johnson has agreed to serve as Acting Director, Computational Science Research & Partnerships (SciDAC) Division.

“Fred’s leadership in the HECRTF plan, broad interagency experience, and substantial program management experience in the Division will be an asset to all,” Strayer said. “I am also pleased to announce that Walt Polansky has agreed to focus his expertise on the SciDAC activity within the Division. I want to take this opportunity to offer my heartfelt thanks to Walt for his tenure as Acting Division Director and his continued contributions to ASCR and the Office of Science. I look forward to working with Fred and Walt as we tackle oncoming challenges.”

Update on Computational Research and Theory (CRT) Facility Today

Lab employees interested in getting an update on two proposed Berkeley Lab projects, the Helios Energy Research Facility and the Computational Research and Theory (CRT) Facility, are invited to attend a brown bag lunch today (Sept. 24) at noon in the Building 50 auditorium. Director Chu will discuss the importance of the two facilities to the Lab’s research goals, and take questions from the audience. Light refreshments will be served.

To learn more about the two proposed facilities, go to http://www.lbl.gov/Community/index.html.

Analytics Team, Visualization Group Welcome Two New Members

The NERSC Analytics Team and CRD Visualization Group recently welcomed two new members: Prabhat (who goes by a single name) and Daniela Ushizima, who will split her time between the Mathematics and Visualization/Analytics groups.

Prabhat previously worked as a graphics system analyst at the Center for Computation and Visualization (CCV) at Brown University for six years. His research interests include computer graphics, scientific visualization, high-performance rendering, human-computer interaction, general-purpose computation on graphics processors, and machine learning.

At CCV, Prabhat supported a variety of interdisciplinary scientific projects ranging from virtual archaeology, high-dimensional mathematics, developmental biology, and computational neurosciences to planetary geosciences. For example, he worked with geoscientists on developing a virtual terrain exploration tool for missions to Mars.

Prabhat earned a bachelor’s degree in computer science from the Indian Institute of Technology in New Delhi in 1999 and a master’s degree in computer science from Brown in 2001. For his graduate study, he worked on the interactive visualization of four-dimensional objects using the CAVE Automatic Virtual Environment. Originally developed in the Electronic Visualization Laboratory at the University of Illionis in Chicago, the CAVE consisted of a room with several large screens for projecting images on the walls and the floor, creating a virtual reality.

Daniela Ushizima comes to Berkeley Lab after spending two years as an assistant professor at the Catholic University of Santos in Brazil. She earned a Ph.D. in Applied Physics and Computing Vision from the University of Sao Paulo’s Physics Institute of Sao Carlos in 2004, after she obtained a master’s degree at the same institute. Ushizima graduated from the Federal University of Sao Carlos in Brazil with a bachelor’s degree in Computer Science in 1997. She was also a visiting researcher in the Electrical and Computer Engineering Department at UC Santa Barbara in 2004.

While at the Catholic University of Santos, Ushizima taught in the Master’s Degree Program as member of the Intelligent Systems Group in the Department of Informatics. She led several government projects funded by the Fundação de Amparo à Pesquisa do Estado de São Paulo (Foundation for Research Support of the State of São Paulo, or FAPESP). From 2005 to 2007, she led the work on computer vision in leukemia diagnosis. Ushizima also served as an industry consultant for several companies in Brazil, including Natcomps, Fleury Institute of Clinical Analysis, and Ablevision.

The Visualization/Analytics folks recently said goodbye to Kurt Stockinger, who will be moving to Switzerland in a few weeks.

SIAM Conference Extends Submission Deadlines

The organizing committee for the 2008 SIAM (Society for Industrial and Applied Mathematics) Conference on Parallel Processing for Scientific Computing is seeking proposals for minisymposia at the conference, to be held March 12–14, 2008 in Atlanta. A minisymposium consists of four 25-minute presentations, with an additional five minutes for discussion after each presentation. Prospective minisymposium organizers are asked to submit a proposal consisting of a title, a description (not to exceed 100 words), and a list of speakers and titles of their presentations. It is recommended that the minisymposium organizer make the first presentation. Each minisymposium speaker should submit a 75-word abstract. The organizing committee will referee minisymposium proposals. The number of minisymposia may be limited to retain an acceptable level of parallelism in the conference sessions.

The submission deadlines have been extended to October 1, 2007 for minisymposium proposals and October 8 for abstracts for contributed and minisymposium speakers. Visit http://www.siam.org/meetings/pp08/participation.php to submit. For more information about the conference, visit http://www.siam.org/meetings/pp08/ or contact the SIAM Conference Department at meetings@siam.org.

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
