Janna Levin (@jannalevin) is the Tow Professor of Physics and Astronomy at Barnard College of Columbia University.

Janna is also director of sciences at Pioneer Works, a cultural center dedicated to experimentation, education, and production across disciplines, as well as Pioneer Works’ virtual home, The Broadcast. Janna’s books include How the Universe Got Its Spots and the novel A Madman Dreams of Turing Machines, which won the PEN/Bingham Prize. In 2012, she was the recipient of a Guggenheim Fellowship, a grant awarded to those “who have demonstrated exceptional capacity for productive scholarship.” Her last book, Black Hole Blues and Other Songs from Outer Space, is the inside story on the discovery of the century: the sound of spacetime ringing from the collision of two black holes over a billion years ago.
