She and Graham have collaborated on many projects, talks, and exhibitions combining interviews and photography, working with participants to challenge stereotypes and broaden understanding about complex issues and stigmatized groups. In 2019, they co-curated the exhibition Beyond Addiction: Reframing Recovery, which debuted in New York City and traveled to Rochester, NY in 2020 and Oxford, MS in 2023. In 2014, Susan and Graham were awarded a fellowship from the Alicia Patterson Foundation for their project American Exile, photos and interviews documenting the stories of immigrants who have been ordered deported from the United States. That series was exhibited at Photoville in New York City and the Head On photography festival in Sydney. They currently facilitate an art and storytelling workshop with participants at VOCAL-NY in Brooklyn.
