My main research areas are the development of novel MR and MR-PET methods including data acquisition, image reconstruction and multimodality data analysis, and application of machine learning in the medical imaging domain. I am also active in translating fundamental medical imaging development and scientific discoveries into real-world applications.
I am affiliated with the following organisations:
I am an ISMRM annual meeting committee member (2018-2021).
I am a member of the following societies: (i) IEEE EMBC, (ii) Society for Neuroscience, (iii) SNMMI, (iv) MICCAI.
Review Editor for Frontiers of Neuroscience.
Academic Editor for PLoS One
I review for a broad range of journals in biomedical imaging and image processing, and review for competitive grant schemes.
