Janna Levin is an American theoretical cosmologist, astrophysicist, and novelist known for work on chaos in general relativity, the topology of the universe, and gravitational waves. She has held faculty positions at Barnard College, Columbia University, and the Massachusetts Institute of Technology, and has written both technical research and public-facing books and essays. Her career bridges research in black hole dynamics, cosmic microwave background topology, and the observational hunt for LIGO and gravitational waves.

Early life and education

Born in New York City, Levin attended public schools in Queens before studying physics and mathematics. She completed undergraduate and graduate studies at the Massachusetts Institute of Technology and earned a doctorate in physics from Harvard University under the supervision of James B. Hartle. During her education she engaged with topics related to general relativity, chaos theory, and early-universe cosmology, interacting with researchers affiliated with institutions such as Princeton University, Caltech, and the Institute for Advanced Study.

Academic career

Levin began her academic career with postdoctoral positions and fellowships that connected her to research centers including the California Institute of Technology, the Kavli Institute for Theoretical Physics, and the Institute for Advanced Study. She joined the faculty at Barnard College and Columbia University, holding the position of professor where she taught courses linked to astrophysics, cosmology, and mathematics. Levin has been a visiting researcher at the Massachusetts Institute of Technology and collaborated with scientists from projects such as LIGO Scientific Collaboration, the Planck satellite team, and researchers at Stanford University and Yale University.

Research contributions

Levin made early contributions to the study of chaotic dynamics in the context of general relativity and binary systems, analyzing unstable orbits around rotating black holes and their implications for deterministic chaos in astrophysical settings. Her work on cosmic topology explored possible nontrivial global shapes of the universe by examining signatures in the cosmic microwave background and considering models like the Poincaré dodecahedral space and compact hyperbolic manifold scenarios studied in connection with the Wilkinson Microwave Anisotropy Probe and Planck results. She has written on the theoretical foundations and observability of gravitational waves, contributing to the dialogue between theory groups and experimental collaborations such as LIGO, VIRGO, and proposals related to the LISA mission. Levin’s interdisciplinary approach connected mathematical techniques from dynamical systems theory and topology with observational programs linked to Keck Observatory, the Hubble Space Telescope, and ground-based observatories.

Publications and popular writing

Levin is the author of scholarly articles in journals that include Physical Review Letters, Classical and Quantum Gravity, and The Astrophysical Journal, addressing topics from relativistic chaos to cosmic topology and gravitational-wave phenomenology. She wrote the trade books "How the Universe Got Its Spots" and "Black Hole Survival Guide", which discuss ideas about cosmology, topology, black holes, and observational tests for lay audiences while engaging with cultural venues such as The New Yorker, The New York Times, and Scientific American. Levin’s essays and interviews have appeared in outlets including NPR, BBC, and programs connected to institutions like the American Museum of Natural History and the Royal Society.

Awards and honors

Levin has received recognition from academic and public institutions for both research and communication, including grants and fellowships linked to the National Science Foundation, the John Simon Guggenheim Memorial Foundation, and societies such as the American Physical Society and the American Association for the Advancement of Science. She has been invited to lecture at conferences and colloquia hosted by Cambridge University, Oxford University, the Kavli Prize forums, and international meetings of the International Astronomical Union and American Astronomical Society.

Personal life and media appearances

Levin is also a novelist and has engaged with the arts community through appearances at venues like The Metropolitan Museum of Art, Lincoln Center, and collaborations crossing into film and theater festivals such as Sundance Film Festival and the Tribeca Film Festival. She has appeared on television and radio programs produced by PBS, NPR, and BBC Horizon, discussing topics from black holes to the hunt for gravitational waves and the philosophical implications of cosmology. Levin lives in New York City and participates in public science outreach with museums, universities, and science festivals.
