Cambridge Language Sciences

Interdisciplinary Research Centre


I began my undergraduate studies as a mathematician at Trinity College, Cambridge, before switching to a masters in computer science, focusing on computational linguistics.  I then spent one year studying at Saarland University and working at DFKI (the German Research Centre for Artificial Intelligence), before returning to Cambridge to pursue a PhD under the supervision of Ann Copestake, which I completed in 2018.  I am currently a Research Fellow at Gonville & Caius College, a Departmental Early-Career Academic Fellow at the Department of Computer Science and Technology, and an Executive Director of Cambridge Language Sciences.

I was born in Singapore and grew up in London.  I speak English (native), German (fluent), French (fluent), Hokkien (intermediate), Mandarin (intermediate), and bits and pieces of others, including Greek, Georgian, Swedish, Dutch, and Rhine-Franconian.


The main focus of my research is on semantics.  How should meaning be represented, and how can those representations be learnt?  I approach this with a foot in two worlds: the logical world of formal semantics, and the data-driven world of distributional semantics.  The aim of formal semantics is to develop mathematical models of meaning, with a particular focus on semantic composition and logical inference.  The aim of distributional semantics is to develop computational models of meaning, using algorithms that can be run on a corpus of text.  Combining the two opens up new opportunities.  From the computational perspective, formal semantic structure enables a model to learn and generalise more effectively.  From the formal perspective, a computational model allows us to tackle research questions that would be impossible to handle with pen and paper.

For a gentle overview of my work, see the following one-hour talk I gave at the ILFC Seminar jointly organised by Université Paris Cité and Université du Québec à Montréal: "Learning meaning in a logically structured model: An introduction to Functional Distributional Semantics"

I have more general research interests beyond semantics, including: machine learning (how can models work with structure?), philosophy of language (what does it mean to know a language?), morphosyntax (what are the components of language?), and NLP for low-resource languages (how can we make sure NLP works for everyone?).

I am also keen to support researchers in the humanities and social sciences who would like to use machine learning to further their work.  If you would like to discuss any ideas (whether you're at an exploratory stage, or looking for technical feedback), please don't hesitate to get in touch!
