Ethan Siegel

Ethan was born in New York City as the son of a Jewish postal worker. He did his undergrad at Northwestern, taught public school in Houston, Texas and Los Angeles, California, before moving to Florida, where he got his PhD in theoretical astrophysics at the University of Florida. After that, he moved to Madison, Wisconsin, where he taught at the University of Wisconsin, ate too much cheese, and also met his life partner, Jamie. After working in astrophysics research at the University of Arizona and starting the world-renowned science blog, Starts With A Bang, he moved from the hellish desert to rain-soaked Portland in 2008. Since then, he's been a professor at the University of Portland and Lewis & Clark College, grown a nationally renowned beard and mustache, got invited to join a circus and probably drank more beer than a healthy person should. He currently works as the head curator at Trapit, and can't wait to tell you a little bit more about the Universe.
