Early life and educationEdit
Siegel worked at Fermilab in 1997. He received his undergraduate degree in physics, classics and integrated science from Northwestern University in June 2000. He was unsure whether to continue studying and took the GRE Physics Test "just in case". He taught in high school in Houston and at King Drew Magnet High School of Medicine and Science in inner-city Los Angeles for a year and though he "liked some aspects" of teaching he then decided he did not want to teach any longer, had a crisis and, influenced by Carl Sagan's Cosmos, he went back into academia to study the universe.
He studied theoretical cosmology, in particular cosmological perturbation theory, at graduate school at the University of Florida with advisor Prof. Jim Fry from 2001. He received his PhD in 2006. During his graduate studies he was a teaching assistant and lecturer in physics, he sat on the graduate student affairs committee, and he was an assistant coordinator for REU students.
Siegel was a teaching assistant in undergraduate general physics at the University of Wisconsin in Spring 2007  and then took up a post-doctoral research post at the University of Arizona, known for its physics research. In 2008, Siegel moved with his then fiancée to Portland, Oregon, after deciding to not pursue an ambitious research career with long hours and instead focus on science outreach and have a "fuller, richer life". He taught at the University of Portland and then Lewis & Clark College, where he is a visiting assistant professor. He later became science and health editor for Trapit. He moved to Toledo in late 2014, while continuing to occasionally teach at Lewis & Clark.
In December 2015 Siegel published his popular science book Beyond the Galaxy: How Humanity Looked Beyond Our Milky Way and Discovered the Entire Universe with World Scientific, which he said is for "people who are curious and intelligent but don’t have scientific backgrounds". In the book, Siegel critiques the MOND theory of gravity, arguing "its failure to meet the criteria of reproducing the successes of the already-established leading theory means that it has not yet risen to the status of scientifically viable." Greg Laden compared it to Isaac Asimov's "The Intelligent Man's Guide to the Physical Sciences", physicist Sabine Hossenfelder said it "is the missing link between cosmology textbooks and popular science articles", and PhD student Jonah Miller said it is "one of those rare books that not only communicates scientific ideas, but communicates what science itself is all about."
In 2012 and 2015, he was the Science Guest of Honor and toastmaster at MidSouthCon, where he promoted the joy of science. In April 2017, he will be the Science Guest of Honor at Norwescon 40. Siegel wears costumes such as a wrestler or superhero to attract attention to his science communication.
Siegel began his blog Starts With a Bang in January 2008 at startswithabang.com and then ScienceBlogs from March 2009. As of 2016, his blog was also hosted on Forbes and mirrored on Medium.com. The blog includes a monthly podcast and Siegel posts answers to questions from readers in the "Ask Ethan" series. He hosts guest bloggers, including Sabine Hossenfelder and Paul Halpern. Topics he has covered include adaptive optics, using lasers in astronomy to adjust for atmospheric turbulence, the detection of gravitational waves from colliding black holes by LIGO, and why quantum entanglement does not allow faster-than-light communication. By January 2011, his blog had been viewed 2 million times.
Described as "beautifully illustrated and full of humour", his blog won the 2010 Physics.org award for best blog, judged by Adam Rutherford, Alom Shaha, Gia Milinovich, Hayley Birch, Lata Sahonta, and Stuart Clark and the people's choice award, and his post "Where Is Everybody?" came third in the 2011 3 Quarks Daily science writing awards, judged by Lisa Randall, winning a "Charm Quark" for "[taking] on the challenge of simplifying probability estimates without sacrificing the nature of the enterprise or suppressing the uncertainties involved". Siegel headed the RealClearScience list of top science bloggers in 2013, as his "unmatched ability to describe the nearly indecipherable made him an easy choice for #1." Siegel also wrote a column for NASA, The Space Place.

Siegel lived in Portland from 2008 and has lived in Toledo, Washington since 2014. He is married to Jamie Cummings, who he met in Madison, Wisconsin. He has a large beard and moustache and wears a kilt; with Jamie he entered the West Coast Beard and Mustache competition in Portland in 2011. He is "often asked why he doesn’t look like a scientist". Siegel is Jewish and an atheist. He plays online chess and is a fan of My Little Pony.
