Nobel Prize Announcement is Reason for UT Dallas Team to Celebrate
As the winners of the 2013 Nobel Prize in physics were announced Tuesday, UT Dallas physics professor Dr. Joe Izen was at a conference in Morocco, surrounded by fellow physicists watching the announcement live via webcast. “Our room erupted in spontaneous applause as the prize was announced,” Izen said. The Royal Swedish Academy of Sciences awarded the prize to theorists Peter Higgs of Britain and Francois Englert of Belgium in recognition of their work developing the theory of how particles of matter acquire mass. Hundreds of U.S. scientists, including a team from UT Dallas led by Izen, also have reason to celebrate. These experimentalists confirmed the theorists’ ideas in July 2012 when they discovered the so-called Higgs particle, or Higgs boson, at the CERN research facility in Geneva.
Prof Honored for Ability to Unlock Secrets of Physics
Dr. Joseph Izen, professor of physics at UT Dallas, is one of two faculty members to receive a 2012 Regents’ Outstanding Teaching Award, which recognizes extraordinary performance and dedication to excellence in the classroom. A total of 65 educators from institutions within the University of Texas System received the 2012 award, which is the highest honor given by the UT System Board of Regents. Izen learned of his Regents’ Award selection while working on an experiment called ATLAS at the Large Hadron Collider at CERN, the European Laboratory for Particle Physics located near Geneva, Switzerland. As a member of the ATLAS team, Izen was part of an international research collaboration that recently found compelling evidence for the Higgs boson, a long-sought-after elementary particle.
Regents' Teaching Awards Praise 2 UT Dallas Profs
Two UT Dallas professors are among the 65 faculty members from institutions across The University of Texas System that have been honored by the UT System Board of Regents as recipients of the 2012 Regents’ Outstanding Teaching Award. The UT Dallas honorees are Dr. Joseph Izen, professor of physics; and Dr. Clint Peinhardt, an assistant professor of political science. “We have a responsibility as a Board to support, encourage and reward our most innovative and effective educators. These annual awards help advance a culture of excellence and recognize outstanding performance in the classroom and laboratory that directly benefit our students for life,” Regents’ Chairman Gene Powell said. “On behalf of the Board of Regents, I congratulate each of these dedicated professionals for their commitment to exceptional teaching and providing an education of the first class for our students.”
Musical Forces Collide
What began as entertainment at a dinner to celebrate the construction of a Large Hadron Collider (LHC) experiment at the CERN laboratory in Switzerland culminated in an unusual side project among scientists, including UT Dallas’ Dr. Joe Izen. Izen, professor of physics and principal investigator for the UT Dallas High Energy Physics Group, works on the ATLAS experiment studying the head-on collisions of high-energy particles. Upon joining ATLAS in 2007, Izen quickly discovered fellow scientists there shared his interest in playing music. After coming to Dallas to work on the Superconducting Super Collider (SSC) in 1991, Izen formed a band called Squirrelheads in Gravy to play old-time Southern mountain music for contra dances hosted by the North Texas Traditional Dance Society.
UT Dallas Physicists Play Role in Higgs Quest
University of Texas at Dallas researchers played a role in groundbreaking experiments that led to the discovery of a new elementary particle of matter, one that is “consistent” with the long-sought-after Higgs boson. When the much-buzzed-about July 4 announcement of the new particle was made by officials at the CERN research facility in Geneva, UT Dallas faculty members, postdoctoral scientists and students involved in the research were positioned around the globe – in China, Australia and Europe. The research results were so highly anticipated by the scientific community that investigators on-site at CERN, including UT Dallas physics undergraduate student Cyrille Chiari, lined up the night before just to get a seat in the packed auditorium for the early-morning statement. “To give an idea of how motivated people here are, the fire alarm went off and no one moved an inch,” Chiari said in an email. “It went on for 10 minutes and still no one left.”
