Honorary Research Fellow in Philosophy

Dr de Waal’s primary research interests concern Plato’s epistemology and metaphysics.  She also has a strong interest in contemporary Philosophy of Mathematics.  


Her current research focuses on the role of mathematics in Plato’s philosophy – especially the intermediary role it plays in facilitating cognitive development; and the role of images in Plato’s philosophy – in particular, whether images, broadly construed, can be seen to play a positive epistemological role on Plato’s account.  


Tamsin completed an MPhil in Ancient Philosophy at Cambridge, and her PhD at King’s College London.  She has taught at UCL and King’s, lecturing in both Ancient Philosophy and Philosophy of Mathematics, and has recently spent time in the US as a Visiting Scholar in Philosophy at NYU, Columbia, and Penn.
