Jason Boulet, Honours B.A. (Minor in Classics), M.A. , Ph.D. (English Language and Literature)

Jason completed his undergraduate degree at Mount Allison University and his master’s degree at Queen’s University. He then completed his doctoral studies at Queen’s, where his research was funded by a Social Sciences and Humanities Research Council (SSHRC) Canada Graduate Scholarship. For his graduate studies, Jason chose to specialize in Victorian literature (c. 1832-1901), with an emphasis on poetry, Pre-Raphaelitism, aestheticism, and decadence. Jason has published academic articles and book reviews in peer-reviewed journals, including the Journal of Pre-Raphaelite StudiesVictorian Poetry, and the University of Toronto Quarterly. In his time at Queen’s University as a teaching assistant and instructor, Jason acted as full instructor in courses at the first-, second-, and fourth-year levels, in areas including British literature from 1790 to the present, Romantic poetry and poetics (c. 1790-1832), Victorian literature and culture (c. 1832-1901), nineteenth-century constructions of selfhood, Gothic fiction and monstrosity, fin-de-siècle literature and culture (c. 1885-1900), and gender studies.

Jason is a dedicated and passionate teacher, who believes in taking an interdisciplinary approach that connects the cultural riches of the past to the everyday experiences and concerns of his students. He encourages them to develop (or simply to deepen) a genuine enthusiasm for the arts and humanities, improving their critical thinking, reading, and writing skills in the process.

Associate Instructor

Joel Benabu, Honours B.A. (English and Theatre), Ph.D. (Renaissance Theatre in England – Shakespeare)*

Dr. Joel Benabu is a Lecturer at the Department of Theatre at the University of Ottawa, Canada. His research interests include English Renaissance drama (Shakespeare’s stagecraft, specifically), theory of drama and performance, and Ancient rhetoric. Recently he has been researching Jewish Canadian Theatre as well as Israeli/Palestinian Theatre. Among his publications are: “’Shakespeare’s Technique of Opening: ‘Strands of Action’”, Theatre Topics, The Johns Hopkins University Press; “Shakespeare and the Rhetorical Tradition: Towards Defining the Concept of an “Opening”, Rhetoric Review, Routledge; “Shakespeare’s Stagecraft in Constructing an Opening: Macbeth”, The Shakespeare Newsletter; and “Shakespeare’s Macbeth: The Challenge of Reading a Theatrical Opening”, Mediaevalia. Joel’s book manuscript, A Playwright at Work: Shakespeare and the Construction of Openings, has recently been prepared for press review. Joel has acted in and directed for the theatre.

Over the years, Joel has taught a broad variety of university courses in the humanities as well as courses in academic writing, critical thinking, and oral presentation. Closely aligned with Brain Power’s mandate, Joel’s pedagogical philosophy maintains that students thrive best in a learning environment that challenges and empowers them. Consequently, his teaching method is less about imparting information and more about giving students the tools to forge their own pathways of knowledge. This can be achieved most effectively by helping students build a diverse skill set and confidence over time. In order to do so, all of Joel’s courses at Brain Power will work with creative pedagogical tools (developing new ways of engaging students) and assess the pedagogical tools developed in order to improve learning objectives over time. Joel’s overarching goal as an instructor at Brain Power is to make students realize their full potential to make a difference in their own lives as well as the lives of others in their community.

*This is a unique stream of direct-entry to Ph.D. (post B.A.) for the top 2% of students in the country.
