About

I am a Senior Lecturer (≈ Assistant Professor) in the Department of Computer Science at the University of Cape Town. My research area is Natural Language Processing and Machine Learning. My current research focuses on language modelling for low-resource languages, modelling knowledge and linguistic structure in text, and creating language resources and models for South African and African languages.

Previously, I was a postdoctoral researcher at the University of Washington, working with Yejin Choi. I completed my PhD at the University of Oxford, supervised by Phil Blunsom. Before that I obtained Masters and undergraduate degrees in Computer Science at the University of Stellenbosch in South Africa.
