Biography

George is an Associate Professor in Machine Learning and also the Programme Director of the highly successful and innovative MSc AI programme. George has a strong interest in both theoretical aspects of Machine/Deep Learning, e.g. capsule networks, domain adaptation, self-supervised learning etc., as well as applications, e.g. data imputation in environmental data of COSMOS-UK network (PI in NERC/EPSRC project ENTRAIN), homomorphic encryption with deep learning for enabling data sharing and analytics in food industry (PI - IoFT network plus EPSRC project), anomaly detection in nuclear reactors (Co-PI in H2020 project Cortex - 20 EU partners in total), Optimising retail refrigeration systems with machine learning (Co-PI-IUK project with Tesco), forecasting yield in strawberries and tomatoes (Co-PI-EU Interreg project SmartGreen and PhD studentship), Gas Turbine availability and fault prediction with Siemens Lincoln, etc.

Previously I was a Senior Lecturer at the University of Lincoln, before that a Senior Data Scientist at IBA Dosimetry in Germany and a Marie Curie FP7-ITN Fellow.

I am serving as programme committe in various tier 1 venues, such as NeurIPS, ICML, AAAI, ICLR, IJCAI, etc. and am participating in the UK AI Council’s Data Working Group ecosystem. I am also a member of the Full College of EPSRC and have been a college member of the UKRI FLF scheme, serving as interview and sift panel member. I am also serving as External Examiner at Cranfield University (MSc applied AI) and University of Hull. I have also served as external panel member for programme validation events.

My publication record includes more than 30 articles in leading venues, covering theoretical aspects on machine/deep learning as well as some highly impactful applications on nuclear reactors, refrigerations systems, agri-food, gas turbines and healthcare.

I have successfully supervised PhD students and have served as PhD viva examiner.

I am currently supervising 7 PhD students.

Research Overview

I am interested in problems revolving around deep learning and machine learning, more speficially on domain adaptation, variational inference and self-supervised learning. I am also working on novel neural network architectures, such as Capsule Networks.

In terms of application areas, I have a strong interest in problems that ML can provide solutions primarily in environmental, industrial, food and healthcare settings.

My past and current activity involves working with national and international collaborators on nuclear reactor perturbation analysis, optimising retail refrigeration systems, gap filling in environmental time-series, domain adaptation for food retail packaging image quality detection, disease detection, and yield forecasting for strawberries and tomatoes


Current Research

I am currently working on the following problems across a several funded projects:

a) Detecting various types of perturbations via neutron noise modelling and deep learning. We are using simulated and real data for various types of nuclear reactors. The data are provided by our EU partners (EU-H2020, 2017-2021, http://cortex-h2020.eu/)

b) Gap filling in environmental time-series, specifically for the Cosmos-UK network. We are developing new data imputation techniques in order to fill the gaps in the time series using historical data from most of the Cosmos-UK sites across the UK (https://www.ceh.ac.uk/our-science/projects/entrain)

c) New routing algorithms for Capsule Networks in order to improve their run time and performance, whilst reducing the number of parameters

d) Yield forecasting for strawberries - we use mobile robots to collect data in a setting that our collaborators at the Univeristy of Lincoln have in the Riseholme campus. We collect time-series, image, depth and video data, so that we can develop new machine learning techniques that can accurately and robustly forecast yield in 1-, 2- and 3- weeks ahead

e) Predicting availability of gas turbines, a collaboration with Siemens Gas Turbines


Collaborations

UK:

a) Centre for Ecology and Hydrology, Wallingford, with Matt Fry, Jon Evans, Steve Cole, Mike Bowes and John Wallbank

b) British Geological Survey, Keyworth, with Andy Kingdon and john Bloomfield
