Lisa Randall, Ph.D. is Professor of Physics at Harvard University, whose studies have made her among the most cited and influential theoretical physicists. She was named one of the "75 Most Influential People of the 21st Century" in 2008 by Esquire Magazine, one of the "100 Most Influential People in the World," by Time in 2007, one of 40 people featured in The Rolling Stone "40th Anniversary Issue", 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". A sought after keynote speaker, Randall is a regular participant in TED, has given a Guggenheim presentation, and spoken at the Whitney Museum debate, the Rubin Museum, the 92nd St Y, as well as at science museums, such as the Museum of Natural History, the Boston Museum of Science, and the Smithsonian. She has also had a public presence through her writing, lectures, and radio and TV appearances. Her book Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions (Ecco) was a New York Times 100 notable book of 2005. Her latest book is the New York Times best-seller Knocking on Heaven's Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World (Ecco).

Randall has received numerous awards and honors for her scientific endeavors. She is a member of the National Academy of Sciences, the American Philosophical Society, the American Academy of Arts and Sciences, was 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 2006, she received the Klopsteg Award from the American Society of Physics Teachers (AAPT) for her lectures and 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. Randall's work has been featured in Time magazine, the New York Times, the Los Angeles Times, Rolling Stone, The Economist, New Scientist, Science, Nature, and elsewhere. Fellow scientists have cited her research more often than that of any other theoretical high-energy physicist in recent years, and she was the first tenured woman in the Princeton physics department and the first tenured woman theorist at M.I.T. and Harvard.

In Knocking on Heaven's Door, Randall explores the latest developments in physics that have the potential to radically revise our understanding of the world: its makeup, its evolution, and the fundamental forces that drive its operation. An expert on both particle physics (the study of the smallest objects of which we know) and cosmology (the study of the largest), she shows how we decide which scientific questions to study and how we go about answering them; she examines the role of risk, creativity, uncertainty, beauty, and truth in scientific thinking through provocative conversations with leading figures in other fields (such as the chef David Chang, the forecaster Nate Silver, and the screenwriter Scott Derrickson); and she explains with wit and clarity the latest ideas in physics and cosmology, including the aims of the biggest and most expensive machine ever built: the Large Hadron Collider, the enormous collider below the border of France and Switzerland. Nearly 27 kilometers in circumference, it has within it both the hottest spot in the galaxy and the coldest, and features the most powerful supercomputer system in the world.

Randall's newest book, Dark Matter and the Dinosaurs (Ecco), brings together these two unlikely phenomena posing the question, “what if dark matter was responsible for the extinction of land-dwelling dinosaurs?” Positing the existence of a previously undiscovered type of dark matter that interactions with forces other than gravity, Randall proposes that there is a disk of this dark matter embedded in the midplane of the Milky Way. This disk might be responsible for knocking comets out of the Oort Cloud and causing periodic extinctions, including that of the dinosaurs 65 million years ago. It explains how the Universe came to exist as it does, the nature and role of dark matter, and how we know it is present.

Randall has also recently pursued art-science connections, writing a libretto for Hypermusic: A Projective Opera in Seven Planes that premiered in the Pompidou Center in Paris and co-curating an art exhibit Measure for Measure for the Los Angeles Arts Association. Randall earned her Ph.D. from Harvard University and held professorships at MIT and Princeton University before returning to Harvard in 2001. She lives in Cambridge, MA.

Praise for Knocking on Heaven's Door:

"Lisa Randall has written Knocking on Heaven's Door in the same witty, informal style with which she explains physics in person, making complex ideas fascinating and easy to understand. Her book presents the latest physics developments with excursions into culture and public policy, explaining science in ways that just might make you think differently - and encourage you to make smarter decisions about the world."
-- President Bill Clinton

"Explores some of the biggest ideas in contemporary physics and how they undergird such everyday matters as risk assessment, logic, and even our understanding of beauty."
-- Time

"Science has a battle for hearts and minds on its hands: a battle on two fronts - against superstition and ignorance on one flank, and against pseudo-intellectual obscurantism on the other. How good it feels to have Lisa Randall's unusual blend of top flight science, clarity, and charm on our side."
-- Richard Dawkins

"[Randall is] one of the more original theorists at work in the profession today. . . She gives a fine analysis of the affinity between scientific and artistic beauty, comparing the broken symmetries of a Richard Serra sculpture to those at the core of the Standard Model."
-- New York Times Book Review

"Many books call to mind superlatives, but this one has them all. It explains the greatest scientific endeavor in history - one that is exploring the earliest, smallest, largest, and most powerful phenomena in the universe, and that may answer the deepest questions about the nature of physical reality. Lisa Randall's lucid explanations of concepts at the frontiers of physics - including her own dazzling ideas - are highly illuminating, and her hearty defense of reason and science is a welcome contribution to the contemporary world of ideas. Read this book today to understand the science of tomorrow."
-- Steven Pinker

"Startlingly honest [and] beautifully written. . . Randall's calm authority and clarity of explanation are exemplary. . . Like being taken behind the curtain in Oz and given a full tour by the wizard."
