About

A question the field had not been asking

Moral theology asks what a good life is and who is owed what. For a long time it asked those questions as though every person answering them could see the page, climb the step and speak for themselves. Dr. Iozzio's work began from the observation that this was never true, and that a theology which assumes it is producing an account of human flourishing that leaves out a great many humans.

Her Marquis citation records her as among the first scholars to integrate disability studies into Catholic moral theology. What that means in practice is a body of teaching, writing and editorial work built on intersectionality, Catholic social teaching, and the full personhood of disabled people.

She has taught at Boston College since 2013. Before that she spent two decades at Barry University in Miami, from 1993 to 2013.

She attributes the work to perseverance, a deep concern for those who have been marginalised or abused, and a refusal to let moral theology sit outside contemporary argument.
