  • Prof. Connie Chang-Hasnain has been awarded a 2009 Guggenheim Memorial Foundation Fellowship.

    Guggenheim Fellows are appointed on the basis of stellar achievement and exceptional promise for continued accomplishment in their field and were chosen from a group of almost 3,000 applicants.

    April 7, 2009

  • Prof. Connie Chang-Hasnain has been selected as one of the new National Security Science and Engineering Fellows.

    DoD Names Two Additional National Security Science And Engineering Fellows
    DoD Names Inaugural Class of National Security Science and Engineering Fellows

    This is a very prestigious recognition, honoring 8 distinguished scientists and engineers in its inaugural round. Selected from over 350 applicants from all fields of sciences and engineering, the eight researchers from the first NSSEFF competition "are expected to make considerable discoveries in the core science and engineering disciplines underpinning the technology of future DoD systems".

    "Every NSSEFF award--up to $3 million in total direct research support for up to five years--provides DoD with top-tier researchers from U.S. universities, each conducting long-term, unclassified, basic research on challenging technical problems of strategic national security importance," said William Rees, Jr., deputy under secretary of defense for laboratories and basic sciences. "It also affords significant opportunities for Fellows to contribute to research programs within the DoD laboratories."

  • Xiaoxue Zhao wins the 2007-08 Leon Chua Award.
    The Leon Chua award is presented to a graduate student or undergraduate student or recent alumnus for outstanding research in the area of nonlinear science. The award was made possible by a donation from a former student of Professor Chua, Professor S.M. Kang, when he was Head of the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. In January 2001, Dr. Kang was named Dean of the Jack Baskin School of Engineering at the University of California at Santa Cruz. Since March 2007, Prof. Kang is the Chancellor of the University of California, Merced. Please attend the Department's Student Awards Ceremony at 3:00 p.m. on Friday, May 9th in the Hewlett-Packard Auditorium, room 306 Soda Hall, where Wendy will receive recognition for the award. A reception will follow in the Wozniak Lounge, room 430-438 Soda Hall.
