# Janna Levin

### Profile

**Education:**

PhD Theoretical Physics, 1993, M.I.T.

Janna Levin is a Professor of Physics and Astronomy. Her work focuses on theories of the Early Universe, Chaos, and Black Holes. Recently, she has discovered chaotic behavior in binary black hole systems -- systems that should be observable to gravitational wave detectors such as LIGO and LISA. 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. Her second book – a novel, "A Madman Dreams of Turing Machines" – is published by Alfred A. Knopf (2006). She is also the author of the popular science book, "How the Universe Got Its Spots: diary of a finite time in a finite space." In 2003 she received the Kilby Young Innovator Award.
