Research degrees and studentships
We are looking for suitably motivated and qualified individuals who wish to undertake postgraduate research in astrophysics leading to either the PhD or MSc degree. We also offer, if resources allow, part-time PhDs.
Explainable Network and AI-based methods for personalised multi-omic medical data analysis
We are currently offering a funded 3-year PhD in the topic of medical image analysis and diagnosis using machine learning techniques, starting October 2021.
Recent technological developments allow us to collect a tremendous amount of digital personal multi-omic medical data that include clinical parameters, serum and urine biomarkers, or genomic data. Some of these analytes are collected over time and organise serial or longitudinal data. Resulting datasets are frequently characterised by small sample sizes and large numbers of features. This results in that fact that existing machine learning approaches often fail to analyse such data and are prone to overfitting.
One of the ways to analyse multiple features from patients in such setting is to use a network approach such as parenclitic networks [1,2]. Although it was shown to be promising in analysing low sample size multidimensional datasets, there are still unsolved methodological issues such as: i) which topological indices are most relevant for predictive modelling purposes; ii) what are the different network architectures; iii) how to incorporate longitudinal characteristic into the network setting; and, finally, iv) how to make these models transparent and explainable. This latter is crucial in order to be able to interpret such black box approach and identify which particular patterns in the data have led to a specific classification result. In the present project we plan to develop a network and AI methodological approaches to challenge these questions.
