With the publication of her first book Postcolonial Theory: A Critical Introduction in 1998, Gandhi was described as mapping "the field in terms of its wider philosophical and intellectual context, drawing important connections between postcolonial theory and poststructuralism, postmodernism, Marxism and feminism."[11]
Her next book, Affective Communities, was written to "[reveal] for the first time how those associated with marginalized lifestyles, subcultures, and traditions—including homosexuality, vegetarianism, animal rights, spiritualism, and aestheticism—united against imperialism and forged strong bonds with colonized subjects and cultures".[12] Gandhi traces the social networks of activists in the late nineteenth and early twentieth centuries connecting Edward Carpenter with M.K. Gandhi and Mirra Alfassa with Sri Aurobindo.
Through this work, Gandhi became noted for proposing a "conceptual model of postcolonial engagement" surrounding ethical premises of hospitality and "xenophilia", and for bringing for the first time a queer perspective to postcolonial theory.
Gandhi's third book, The Common Cause, presents a transnational history of democracy in the first half of the twentieth century through the lens of ethics in the broad sense of disciplined self-fashioning.[13] This book has been described as "an alternate history of democracy foregrounding events of errant relation," and "the most thoroughgoing defence of the value of infinite inclusivity to postcolonial studies."[13][14][15]
Leela Gandhi is also a published poet. Her first collection of poems, Measures of Home, was published by Ravi Dayal in 2000, and her subsequent poetry is included in several anthologies.[16][17][18][19]
