I am a final year PhD student at the University of Cambridge Computer Lab, supervised by Prof Simone Teufel within the Natural Language and Information Processing group. I am also a member of Homerton College. Before this, I completed the MPhil in Advanced Computer Science here and did my BSc in Computer Science at the University of Bristol. My master's research, entitled Modelling polysemy in distributional semantic models, looked at how word sense can be explicitly modelled in DSMs and the benefits of doing so. You can download my CV here.

My PhD research is on developing interpretable models for common sense multi-hop reasoning. The premise of this research is that it's important to know which facts a model has used to come to a conclusion so developers can check whether the combination makes sense. I use a knowledge graph to structure these facts and evaluate models on a question answering task. Models typically consist of separate text and graph encoders; interpretability techniques can be applied to the latter to retrieve a graph-structured explanation. I have created an ontology for structuring common sense facts, and my current work is in evaluating whether we can evaluate model explanations against gold standards in this format. I am also investigating the collection of relevant data from an ontology for input into these models.

I am separately interested in how tools from NLP can be used to help researchers in other fields, for example by assisting with data coding or exploration of qualitative data. These tools also have various business use cases. Please reach out if this sounds interesting!

I used to jointly organise the weekly NLIP seminar series. All continue to be welcome to join, especially given the current online format!

Outside of the lab I enjoy Taekwondo and kickboxing, and was the president of the kickboxing society for 2019-20.
