I'm a researcher in the Logic of Conceivability project at the Institute for Logic, Language and Computation at the University of Amsterdam. I'm also affiliated, through the project, with the Arché Research Centre at the University of St. Andrews. I defended my Ph.D in January 2017 at the Stanford department of philosophy. My advisors were Johan van Benthem and Krista Lawlor.

I work on epistemology, logic, and related topics on mind, language and rationality. My research explores the interaction between knowledge, meaning and modality: Google Scholar, Philpapers, Academia.

I'm from South Africa. I studied mathematics and, later, philosophy at University of the Witwatersrand.
