About
I am a lecturer in natural language processing at CIS, University of Melbourne, and a DECRA 2023 fellow.
My research focusses on understanding how humans learn about and represent complex and evolving information in the context of large-scale and noisy environments; and on using these insights to develop fairer and more robust automatic systems. I combine methods from natural language processing, machine learning and computational cognitive modelling. Representative projects include scalable models of
Before joining Melbourne University, I was a postdoc / applied scientist at Amazon Core AI in Berlin, and before that a research associate in the Edinburgh NLP group , ILCC, University of Edinburgh, working with Mirella Lapata and Shay Cohen. I spent research visits at Michael Frank's Language and Cognition Lab at Stanford University, at David Blei's lab at Columbia University.
