After her PhD, Delaney was appointed a Damon Runyon postdoctoral fellow with John Essigmann at the Massachusetts Institute of Technology,[5] where she studied the mutagenicity of oxidized guanine lesions.
Delaney has studied how DNA damage is related to human disease. At Brown University she serves as the Vernon K. Krieble Professor of Chemistry and Chair of the Department of Chemistry. In 2019. she was made director of graduate studies, and she implemented peer mentoring and regular advisor meetings for first year students, a journal club, a coffee hour and a weekly colloquium.[6] She was made Senior Associate Dean of Academic Affairs for the graduate school in 2022.[6] Delaney's focus is to create a simple and insightful blueprint to help understand how damage to DNA can relate to genetic changes and human diseases. She also has interests in how chemistry can be implemented in cooking and how it can influence food, as she teaches a course titled Kitchen Chemistry.[7]
