Lisa Randall is professor of theoretical physics and studies particle physics and cosmology Her research concerns elementary particles and fundamental forces and has involved the development and study of a wide variety of models, the most recent involving extra dimensions of space. She has made advances in understanding and testing the Standard Model of particle physics, supersymmetry, models of extra dimensions, resolutions to the hierarchy problem concerning the weakness of gravity and experimental tests of these ideas, cosmology of extra dimensions, baryogenesis, cosmological inflation, and dark matter. Professor Randall earned her PhD from Harvard University and held professorships at MIT and Princeton University before returning to Harvard in 2001. She is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, a fellow of the American Physical Society, and is a past winner of an Alfred P. Sloan Foundation Research Fellowship, a National Science Foundation Young Investigator Award, a DOE Outstanding Junior Investigator Award, and the Westinghouse Science Talent Search. In 2003, she received the Premio Caterina Tomassoni e Felice Pietro Chisesi Award, from the University of Rome, La Sapienza. In autumn, 2004, she was the most cited theoretical physicist of the previous five years. In 2006, she received the Klopsted Award from the American Society of Physics Teachers (AAPT). In 2007, she received the Julius Lilienfeld Prize from the American Physical Society for her work on elementary particle physics and cosmology and for communicating this work to the public. Professor Randall’s book Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions was included in the New York Times' 100 notable books of 2005. In 2008, Prof. Randall was among Esquire Magazine's "75 Most Influential People of the 21st Century". Randall was included in Time Magazine's "100 Most Influential People" of 2007 and was one of 40 people featured in The Rolling Stone 40th Anniversary issue that year. Prof. Randall was featured in Newsweek's "Who's Next in 2006" as "one of the most promising theoretical physicists of her generation" and in Seed Magazine's "2005 Year in Science Icons".
