Sheila Heti is the author of seven books, including How Should a Person Be? which The New York Times Book Review called an "odd, original, and nearly unclassifiable book," and which was named as a best book of the year by The New York Times, The New Yorker, Salon and many other places. Recently, she published the New York Times best seller, Women in Clothes, a collaboration with Heidi Julavits and Leanne Shapton, featuring the writing of 639 women. Her first book was the collection The Middle Stories (McSweeney's). Next, she published the novel Ticknor (Farrar, Straus & Giroux). With Misha Glouberman, she wrote The Chairs Are Where the People Go (Faber), which The New Yorker chose as one of its best books of 2011. She wrote an illustrated book for children, We Need a Horse, featuring art by Clare Rojas. McSweeney's recently published her play, All Our Happy Days are Stupid.

Her books have been translated into more than a dozen languages. Her writing has appeared in The New Yorker, The Paris Review, Harper's, McSweeney’s, n+1, The Guardian, The Globe and Mail, The New York Times, The London Review of Books and more.

She served as Interviews Editor at The Believer magazine for several years, and has conducted many interviews with writers and artists for the magazine; she is also co-editor of Always Apprentices: The Believer magazine Presents Twenty-Two Conversations Between Writers.

In 2013, her full-length play, All Our Happy Days are Stupid, was produced by Suburban Beast at Toronto's Videofag. PopMatters called it "a triumph of intellectually-engaged theatre." It was remounted to sold-out audiences in 2015 at Harbourfront World Stage in Toronto and The Kitchen in New York.

With Misha Glouberman, she created the barroom lecture series Trampoline Hall, at which three people deliver lectures on subjects outside their areas of expertise, then answer questions from the audience. The shows have been running monthly in Toronto since 2001.

In 2008, she created The Metaphysical Poll, a blog that collected the sleeping dreams people were having about Hillary Clinton and Barack Obama during the Democratic primaries. The blog received hundreds of dreams and press in The LA Times, The Washington Post, Slate, The Economist and elsewhere.

She has taught or spoken at Columbia University, Pomona College, MoMA, the Hammer Museum, Brown University, the New York Public Library, the Cúirt Festival of Literature, Festival Americas, the Sydney Writers Festival, the Vancouver Jewish Book Festival, and other places. She has been in residence at Yaddo, Santa Maddalena, and Fundacion Valparaiso.

She appeared in photographs as Lenore Doolan in Leanne Shapton’s book, Important Artifacts, which she is adapting for the screen. She also appears in Margaux Williamson’s film Teenager Hamlet.
