[6] After participating from 2005 to 2010 in Cave Canem Foundation workshops led by poets such as Marilyn Nelson, Willie Perdomo and Patricia Smith,[7] Sealey decided at the age of 32 to commit to a career as a poet, going on to earn an MFA degree in creative writing at New York University.
[6][8] Her work has appeared in The Best American Poetry 2018 and 2021, The New Yorker, The Paris Review, and other publications.
[2] From 2017 to 2019 she was the Executive Director at the Cave Canem Foundation, and was the curator for a special series of Poem-a-Day (August 31–September 11, 2020).
[2] Sealey began making erasures from the 2015 United States Department of Justice report[10] detailing bias policing and court practices in Ferguson, Missouri, three years after the fatal shooting of Michael Brown by police,[1] and in October 2021, her "Pages 22–29, an excerpt from The Ferguson Report: An Erasure" (published in Poetry London)[11] won the 2021 Forward Prize for Best Single Poem.
[12] The judges of the prize referred to Sealey's use of the report's "stifling obfuscations" to create "new moments of lyrical beauty and contemplation", and called her work "a poem of resonant cultural and social value".
