Frank B. Baird, Jr. Professor of Science, Harvard University Lisa Randall is the Frank B. Baird, Jr., Professor of Science at Harvard University. Professor Randall is one of the most cited and influential theoretical physicists today. Her research concerns elementary particles and fundamental forces and has involved the development and study of a wide variety of models, among them those involving extra dimensions of space. Her current research also centers on theoretical implications of experiments at the Large Hadron Collider at CERN as well as those of searches for dark matter. Professor Randall has also written a book about these topics entitled Warped Passages that was included in the New York Times' "Most Influential Books of 2005." She was among Time Magazine's "100 Most Influential People" of 2007. Professor Randall is a member of the National Academy of Sciences, the American Philosophical Society, and the American Academy of Arts and Sciences. She earned both her B.A. and Ph.D. degrees from Harvard. "New developments in physics have the potential to radically revise our understanding of the world: its makeup, its evolution, and the fundamental forces that drive its operation. The Large Hadron Collider, which houses a 27 km ring accelerating protons to enormously high energies 100 meters underground, contains the most extensive and elaborate experiments ever built. In this lecture I will explore the nature of these experiments and what the tiny distances they will explore might teach us. I will also comment on searches for dark matter at the LHC and elsewhere."
