I am an award-winning mathematics and science journalist whose work has appeared in Quanta, Nature, The Atlantic, New Scientist and many other publications, and has been reprinted in the 2010, 2011, 2016 and 2020 volumes of "The Best Writing on Mathematics."


Episode 59: Erica Klarreich

May 21, 2015 — On this episode of Strongly Connected Components Samuel Hansen talks to mathematics writer Erica Klarreich. They discuss why she had no choice but to go into mathematics because of her family, what triggered her to move from research into journalism, and how she tries to leave her readers with a small sense of doing some of the mathematics she writes about.

Erica Klarreich... Journalist/Mathematician/Ray Smullyan Fan

April 12, 2015 — After I interviewed science/math writer Natalie Wolchover a bit ago, it occurred to me I should interview her Quanta colleague, Erica Klarreich, who actually specializes even more-so in mathematical pieces.

Erica Klarreich Profiles an Award-Winning Mathematician

September 30, 2014 — In March 2014, mathematics and science journalist Erica Klarreich got a rare chance to report exclusively on a top math story. Thomas Lin, the managing editor of Quanta Magazine, had convinced the International Mathematical Union to give him advance notice of the winners of the Fields Medals, which are awarded every four years and are often described as mathematics’ Nobel Prize.

Erica Klarreich - Inspired by Math #22 (65:18)

February 22, 2013 — Erica Klarreich's name came up a couple of times when I asked people who I should interview for the podcast series. So, I looked her up and was impressed with the in depth articles she had written for Scientific American and a number of other publications. Erica Klarreich has been writing about mathematics and science for a popular audience for more than ten years.

Erica Klarreich

I have been writing about mathematics and science for a popular audience for more than 20 years. A mathematician before I became a full-time journalist, I try to convey the essence of complex mathematical ideas to non-mathematicians, and give them a sense of the beauty and depth of mathematics.

I also enjoy plunging into topics far from my mathematical roots, and have written about fields such as economics, computer science, medicine, and biology — often as these fields relate to mathematics, but often simply for their own sake.

As a freelance journalist based in Berkeley, California, I have written for many publications, including Quanta Magazine, Nature,, New Scientist, American Scientist,, Nautilus, and Science News, for which I was the mathematics correspondent for several years. I've also been the journalist in residence at the Mathematical Sciences Research Institute in Berkeley and at the Simons Institute for the Theory of Computing at the University of California, Berkeley. My work has been reprinted in the 2010, 2011, 2016 and 2020 volumes of "The Best Writing on Mathematics."

I received the 2021 Communications Award from the Joint Policy Board for Mathematics, which recognizes journalists and other communicators who, on a sustained basis, bring accurate mathematical information to nonmathematical audiences.

I am a graduate of the science writing program at the University of California, Santa Cruz, and I have a Ph.D. in mathematics from Stony Brook University.
