Danielle Elizabeth Tumminio

In December 2013, Tumminio wrote a blog post for CNN citing support for the Utah Federal District Court decision of Brown v. Buhman which ruled parts of Utah's laws banning polygamy to be unconstitutional, stating "I have become a supporter of them and their lifestyle, though I certainly can understand why others remain opposed ... It's a natural extension for those Christians who support same-sex marriage on theological grounds." Criticism of her statements resulted in a clarifying statement stating she was not advocating for a change in the Episcopal Church's official position opposing polygamous marriage.

In 2011, Tumminio appeared twice as a guest on the television show Sister Wives. On the show, she asked the family questions about their marriage and religion and arranged for them to speak in an academic context.

Tumminio is the author of God and Harry Potter at Yale: Teaching Faith and Fantasy Fiction in an Ivy League Classroom and was the instructor of the "Christian Theology and Harry Potter" seminar at Yale University in the spring of 2008; in 2011, she repeated the course at Tufts University. Tumminio has also presented material on the intersection between theology and the Harry Potter series at the Infinitus Symposium in Orlando, Florida in 2010, the Portus Symposium in Dallas, Texas, in the summer of 2008, and she chaired the panel on Harry Potter and Religion at the 2008 American Academy of Religion conference. Her teaching has been praised by Harry Potter commentator John Granger on his Hogwarts Professor website.

Tumminio is a three-time graduate of Yale University, where she studied with prominent theologians Marilyn McCord Adams, Emilie Townes, Miroslav Volf, and Serene Jones. She pursued doctoral studies at Boston University, beginning in 2008 under the direction of Shelly Rambo and Bryan Stone where she researched trauma, feminist theology, and reproduction. At Boston University, she studied with Elie Wiesel.
