In 2000 Massam took up a role at what is now Pilgrim Theological College in Melbourne (formerly United Faculty of Theology). She was the first Catholic laywoman to be appointed to the ecumenical faculty.[5] Massam served as Pilgrim Theological College's academic dean in 2016 and again from 2018-2020.[2]
Massam's teaching and research interests lie in the areas of Australian religious history and spirituality (especially Benedictine traditions) with a particular interest in cultural and theological understandings of prayer and work. Her work is influenced by postcolonial and feminist perspectives and she has published widely in these areas.[2][6]
In 2020 Massam's book A Bridge Between: Spanish Benedictine Missionary Women in Australia, was one of three books shortlisted for a national prize in Australian history, the New South Wales Premier's History Awards.[7][8] The book stems from a long collaboration with the Aboriginal Corporation of New Norcia and Benedictine communities that served the monastic town of New Norcia, in Western Australia. Massam was invited to discuss the book and the Spanish Benedictine women with historian Meredith Lake, on ABC's Soul Search program.[9][10] The book was also discussed when she was interviewed for the Love-Rinse/Repeat podcast.[11]
