Physics and astromony professor Janna Levin appears in a BBC profile video that highlights her diverse pursuits: science and writing. An excerpt:

"Chaos, black holes and the early universe. These are the pre-occupations of one of the world's leading astrophysicists, Janna Levin.

Professor Levin's study and research have taken her on an academic journey through the Massachusetts Institute of Technology, Cambridge and Oxford Universities and now the faculty of Barnard College at New York's Columbia University.

In a 2011 TED talk she explained why space is not a silent place and how the universe has a soundtrack.

But the pursuit of answers to the unsolved questions of our universe is not Janna Levin's sole preoccupation. She's also a critically acclaimed novelist whose work explores the spaces where science and art intersect."

Watch the video.

Prof. Levin's research focuses on theories of the early universe, chaos, and black holes. She is also interested in the topology of the universe and the question of whether or not the universe is infinite. Other research topics include the cosmology of extra dimensions and string cosmology.  She is the author of the novel A Madman Dreams of Turing Machines as well as the popular science book, How the Universe Got Its Spots: Diary of a Finite Time in a Finite Space.
