Tracy Isaacs

Special Advisor to the Provost on Gender-Based and Sexual Violence

Collective Action Theory, Ethics, Feminist Ethics
BA, MA Toronto; PhD MIT


My research focuses on issues of individual and collective responsibility in collective action contexts, collective obligation, ethics more broadly, including feminist ethics and food ethics. I also work on feminist issues in sport and fitness, food, dieting, and body image. Current projects include a book-in-progress on “imperfect veganism” and a paper on role responsibility in oppressive social contexts.

I am available to supervise PhD projects in any of these areas. Recent supervisions include dissertations on collective responsibility, the ethics of testimony, the role of law in the development of moral agents, a feminist defence of moderate moral intuitionism, and relationally in the context of natural goodness theory.
