Sabine Hossenfelder (born 18 September 1976) is a blogger and Theoretical Physicist who researches quantum gravity. She is a Research Fellow at the Frankfurt Institute for Advanced Studies. She is the author of "Lost in Math: How Beauty Leads Physics Astray", which explores the elegance in fundamental physics and cosmology.

Hossenfelder completed her undergraduate degree in 1997 at Johann Wolfgang Goethe-Universität in Frankfurt am Main.[1] She remained there for a Masters degree under the supervision of Walter Greiner, entitled "Particle Production in Time Dependent Gravitational Fields", which she completed in 2000.[2] Hossenfelder received her doctorate "Black Holes in Large Extra Dimensions" from the same institution in 2003, under the supervision of Horst Stöcker.[3]


Hossenfelder remained in Germany until 2004 as a postdoctoral researcher at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany.[1] She moved to North America and completed research fellowships at the University of Arizona, Tucson, University of California, Santa Barbara and Perimeter Institute, Canada.[4][5][6] She joined Nordita Institute for Theoretical Physics, Sweden in 2009 as an Assistant Professor.[7][8] In 2018 she was a Research Fellow at the Frankfurt Institute for Advanced Studies.[9]

Hossenfelder's research interest is in the phenomenology of quantum gravity.[7] She focuses on the role of Lorentz invariance and locality, which would be altered in the discovery of quantum gravity.[7] Hossenfelder is trying to find experimental evidence of quantum gravity.[10][11][12][13] Since 2007 she has been involved with the annual conference series "Experimental Search for Quantum Gravity".[14] Hossenfelder has created a number of YouTube videos exploring the topic.[15][16][17]

Public engagementEdit

Hossenfelder is a freelance popular science writer who has kept a blog since 2006.[18] She contributes to the Forbes column "Starts with a Bang" as well as Quanta Magazine, New Scientist, Nature, Scientific American and Physics Today.[19][20][21][22][23][24] In 2016, Hossenfelder offered to act as a physics consultant on her blog—$50 USD for twenty minutes of discussion—and had to recruit five extra physicists to deal with the demand.[25][26] In 2017 she created cards featuring pioneering quantum physicists.[27] Live Science and The Guardian quoted Hossenfelder as an authority when trying to evaluate the importance of Stephen Hawking's last scientific publication.[28][29]

Basic Books decided to publish Hossenfelder's first book, Lost in Math: How Beauty Leads Physics Astray, released in June 2018.[30][31][32]
