Dr Gregory teaches across the Literary Studies and Critical Performance Studies programs in the Faculty of Arts. A theatre historian, Dr Gregory is a leading contributor to the field of Actress Studies and a well-established scholar of theatre and performance. In Dr Gregory's own undergraduate and postgraduate studies her engagement with theatre and performance events and practices was intertwined with theories and approaches from literary studies, and her work in both research and teaching has remaines strongly interdisciplinary.

Dr Gregory's research has been published in highly-competitive national and international journals, including Theatre Survey, New Theatre Quarterly, Australasian Drama Studies, Nineteenth-Century Theatre and Film, and the Journal of American Drama and Theatre. Her monograph, Actresses and Mental Illness: Histrionic Heroines, was published by Routledge in 2019. The product of extensive archival research, this monograph offers the first comprehensive investigation of the personal, professional and reputational experiences of the female performer in the context of mental illness and its treatment, and was awarded an Honourable Mention in the Rob Jordan Prize for Best Book by the Australasian Drama Studies Association.

Dr Gregory has been invited to provide expert commentary for forums such as The Conversation, the Daily Review, the New Books Network, ABC Radio and Monash Lens. She has been awarded competitve international research fellowships, including the Everett Helm Visiting Fellowship at the Lilly Library, Indiana University and a Rose Library Fellowship at Emory University.

Dr Gregory's research addresses significant contemporary problems and offers new insights into a range of pressing global issues, including stigma; the lived experience of complex illness; work and aging; and national identity. Current research projects include work on the touring performer and tuberculosis in the early twentieth century; celebrity advocacy for highly stigmatised conditions, such as incontinence and borderline personality disorder; and the recovery of past performance practice through digital archives. 

Dr Gregory welcomes inquiries for Honours and postgraduate supervision in literary studies and theatre and performance studies, especially in celebrity and representation, Shakespearean studies, nineteenth-century literature and performance, and health and medical humanities.
