The Department of Computer Science at University College London is inviting applications from excellent candidates for a three year Research Associate position starting in January 2022 in the EPSRC Programme Grant EP/V026259/1 on the “Mathematics of Deep Learning” (Maths4DL). Maths4DL is a joint programme run by the University of Bath, the University of Cambridge and the University College London, and the successful candidate will join a close knit team hosted by all three universities and led by Prof Chris Budd OBE and Dr Matthias Ehrhardt (Bath), Profs Carola Schoenlieb and Richard Nickl (Cambridge), and Profs Simon Arridge and Bangti Jin (UCL).

The salary will be in the range of  £36,028- £43,533  depending upon age and experience.

This is an exceptional opportunity to conduct ambitious research at the forefront of mathematics, statistics and machine learning. There are generous funds available for conference attendance, travel, computer equipment, training and career development.

The Vision and Ambition of Maths4DL is to develop a comprehensive mathematical, statistical and computational framework that addresses i) the foundational challenges on interpretability of the trained Deep Neural Networks (DNN), ii) robustness and generalisation of DNN on test data, iii) statistical confidence in DNN-outputs and iv) computational challenges with large-scale models and high-dimensional training data.

The three university team which the successful candidate will join, combines leading expertise in deep learning, interdisciplinary mathematics, statistics, Artificial Intelligence (AI), Partial Differential Equations (PDEs), optimal transport, optimisation, environmental modelling, numerical analysis, geometric integration, scientific computing, image processing, probability, and inverse problems.

Duties of the research associate include developing and conducting individual and collaborative research objectives, proposals and projects as part of the overall work of the Maths4DL programme. The research associate must be able to communicate material of a technical nature and be able to build internal and external contacts.
