My research and teaching interests focus on problems that arise at the intersection of ethics, the political, aesthetics, medicine, technology, and the sciences. My work incorporates feminist and decolonial approaches and combines historical with contemporary perspectives in responding to philosophical problems.

I have published extensively in 19th century European philosophy, primarily on the philosophy of Friedrich Nietzsche. My main focus for the past ten years has been on Nietzsche's free spirit writings. Two books have already been published from this research focus, and two more, on Nietzsche's experimentalism, and on Nietzsche's Beyond Good and Evil, are in progress. I also do research in ethics, especially on contemporary bioethical issues and on issues in technology. I have additional research expertise in social and political philosophy, and in African philosophy. 

My recent book, Nietzsche's Dawn: Philosophy, Ethics, and the Passion of Knowledge, was co-authored with Keith Ansell-Pearson and was published by Wiley-Blackwell in 2020: https://www.wiley.com/en-gb/Nietzsche's+Dawn:+Philosophy,+Ethics,+and+the+Passion+of+Knowledge-p-9781118957783
