I'm heading to Tokyo for a three month internship at the R&D department of OLM Digital starting in September 2019. I'll be working on procedural modelling for computer graphics applications.

Mocrosoft HoloLens


I'm joining the Cognition research and development team based at Microsoft's lab in Cambridge as a research consultant over the summer of 2019, working on application of machine learning to problems in computer graphics and vision.

Paper introducing the Autonomous Vehicle Acceptance Model (AVAM), a model of user acceptance for autonomous vehicles, adapted from existing models of user acceptance for generic technologies.

Presented at Intelligent User Interfaces 2019.



I'm taking up a research assistant position at the Computational Media Innovation Centre (CMIC) at the Victoria University of Wellington in New Zealand for three months starting in January 2019.

I'll be working with researchers and industry partners to help develop innovative augmented, virtual and mixed reality technologies.

Microsoft Research


I'm joining Microsoft Research in Cambridge for a three six month research internship starting in summer 2018

I'll be helping to develop the next generation of head mounted displays using digital holography.

Some more details about the project are available here.

Animal Face Alignment

Read Paper

For my fourth year (masters) project I looked at head pose estimation and facial landmark detection for animals, specifically sheep. This included the adaption of deep learning models for sheep head pose estimation and combination with classical techniques to enable accurate facial alignment. This culminated in the implementation of a near real-time pipeline for farm survellience videos, the end-goal being automated livestock health monitoring.

Leaf Identification

Read Paper

Paper presenting a novel feature set for shape-only leaf identification from images. Over 90% accuracy is achieved on all but one public dataset, with top-four accuracy for these datasets over 98%.

Source code available on GitHub.


Read Paper

Paper focussing on the design, deployment and evaluation of Convolutional Neural Network (CNN) architectures for facial affect analysis on mobile devices. The proposed architectures equal the dataset baseline while minimising storage requirements. A user study demonstrates the feasibility of deploying the models for real-world applications.

Source code is available on GitHub.

GP Confidences for CNNs

Read Paper

Paper presenting a hybrid classification technique using Gaussian processes fitted on features extracted by a convolutional neural network to enable estimation of prediction confidence. The classifier is evaluated on the MNIST dataset and shown to have somewhat meaningful implications for confidence estimation.

THJE Website

Website design and other graphics for the 2018 Trinity Hall June Event, in addition to managing the ticketing service provided through Qpay.



I'll be joining the team at Cydar in Cambridge for a two month internship over the summer of 2017.

I will help to develop technologies for medical imaging to be used by surgeons during operations.

Tree Generation

Read Paper

For my third year project I explored the procedural modelling of trees for use in computer graphics.

I implemented two systems which generate tree models of many types within the Blender modelling application, one of which now forms the basis of a fully featured plugin.

Source code available on GitHub.



I'm joining the team at Jagex Games Studio for three months in the summer of 2016 as an intern.

I'll be working on a project as part of a small team aimed at exploring new areas which Jagex may be interested in expanding into in the future.

THBC Site Redesign

View Website

Trinity Hall Boat Club's original website was designed in the 90s and was starting to show its age. I carried out a complete visual redesign and tidied up many aspects of the website code.

I also wrote a new voting system to be used for captaincy elections, as well as updating the content of many of the site's pages and adding some new ones.
