Dr Ali Gooya
- Senior Lecturer in Machine Learning (School of Computing Science)
Ali Gooya is currently a Senior Lecturer in the School of Computing Science (IDA-Section) at the University of Glasgow, Scotland, UK. Before joining the University of Glasgow in 2022, he was an Associate Professor in the School of Computing at the University of Leeds (2018-2022) and the University of Sheffield (2016-2018). He has won multiple prestigious fellowships, including Allen Touring Institute (2022), JSPS short-term invitational (2020), FP7 Marie-Curie IIF fellowship (2014), and Japan Society for Promotion of Science JSPS-PDRA (2008). He earned his PhD from the University of Tokyo in medical image analysis (2007). He joined the University of Pennsylvania as a post-doc research associate to develop machine learning methods for medical vision (2008-2011).
My research interest broadly lies in machine learning, computer vision and medical imaging. I am particularly keen on deep probabilistic learning with the target applications in cancer and cardiac image analysis, computer-aided decision support systems, prediction and marker discovery, statistical inference on populations, and computational anatomy.
My research vision is to aspire to unsupervised machine learning for AI in healthcare, as expert annotations in this particular field are sparse. I am experienced in creating methodologically innovative deep Bayesian frameworks, often involving rigorous mathematical modelling.

Bayesian Deep Atlases for Cardiac Motion Abnormality Assessment by Integrating Imaging and Metadata
Cardiovascular diseases (CVDs) are the second biggest killer in the UK; currently, more than 7 million people live with CVD in the country. Early identification of individuals with significant risk is critical to improve the patient's quality of life and reduce the financial burden on the social and healthcare systems. Many CVDs lead to a shortage of blood supply to the heart muscle, and abnormal motion is diagnosed non-invasively by analysing the patient's dynamic cardiac imaging data. Manual assessment of these images is subjective, non-reproducible, limited to the left ventricle, and time-consuming. Statistical atlases, describing the 'average' pattern of the heart motion over a sizeable healthy population, can be potentially helpful in identifying deviations from normality in individuals. However, the integration of the existing atlases into clinical practice is inhibited by three fundamental limitations: (i) the derived motion statistics are often independent of the patient's age, gender, weight, etc. (metadata) that are essential for precise diagnosis, (ii) the detected abnormalities due to failure of heart segmentation could not be disentangled from the underlying clinical conditions.
To alleviate these fundamental limitations, this proposal aims, for the first time, to develop a complete probabilistic atlas to evaluate bi-ventricular motion abnormalities accurately.
- Holistically integrating imaging and metadata from a large population cardiac imaging study.
- Disentangling the algorithmic segmentation failures from underlying clinical conditions
- Addressing the computational challenge of extending deep transformer models to motion data
The framework will be a novel Bayesian approach extending the recent developments in deep recurrent neural networks (e.g. Vision Transformers). These networks provide a natural mechanism to model sequential data such as 2D video. Yet, using Transformers to model the complex dynamics of the heart motion is conceptually new and powerful. The motion will be modelled as the spatiotemporal (3D+t) sequence of the heart shapes across the cardiac cycle, extracted from cine Cardiac Magnetic Resonance (CMR) images. The atlas will be a recurrent model that, given a sequence, will predict a probabilistic distribution function (pdf) for the following heart status. The critical aspect is that the pdf will be conditioned on the patient's metadata (age, gender, ethnicity, etc.). Thus by measuring the spatial deviations from the expected shape at each phase, the atlas will allow very accurate quantification of anatomical and functional cardiac abnormalities (and variances showing uncertainties) specific to the patients.
We have extensive experience developing Bayesian and non-Gaussian statistical atlases from cardiac shapes and motion. However, the previous work discarded the patient metadata (such as age, gender, ethnicity, etc.). Therefore, the atlas was not clinically deployable to study cardiac motion abnormalities, which are relevant to various CVDs.
The atlas will be derived from the UK Biobank CMR study aiming to scan 100,000 patients by 2022. The training of the atlas will be pursued as the new releases of the data sets from the UK Biobank becomes available. We have established collaboration with this study's clinical advisor and have full access to the CMR data sets.
