From 1992 to 2017, Kwok was teaching at the Episcopal Divinity School in Cambridge, Massachusetts, and was appointed the William F. Cole Professor of Christian Theology and Spirituality.

"[8] Female labor in Asia is something that has been overlooked, as most "women are employed mostly in dead-end, low-skilled or semi-skilled manufacturing jobs, in retail or the service sector.

Writing in feminist theology, postcolonial criticism and biblical hermeneutics, Kwok has maintained as her identity as an Asian woman, incorporating it into her work.

She states that traditional feminist theory has not sufficiently considered the experiences of non-white women, and the effects of colonialism, neocolonialism and slavery.

"[10] The aim of her work is to create a theology that more accurately reflects the multiple levels of oppression that women in postcolonial contexts face.

"[12] For Kwok, the storytelling tradition within many Asian societies offers a rich resource for innovative ways of doing theology as women engage with biblical stories through drama and the sharing of life experiences.
