Research Interests:
Computational neuroanatomy is about a comprehensive structural and functional model of the brain. The distribution of structural changes of human brain reflects the underlying pathology. The increasing sophistication of MRI allows neuroanatomical structures to be visualized in vivo in unprecedented detail. Clinical MRI is able to give good soft-tissue contrast and high spatial (<1 mm) resolution. Due to rapid advances in computing power and algorithm development, we are now well placed to study the extraordinary MRI-visible morphological variability of the human brain through mathematical models sensitive to subtle changes in neuroanatomical shape, complexity and tissue characteristics. However, one of the key requirements of neuroimaging research is the multi-disciplinary collaborations between neuroscience, engineering and medicine and a host of sub-disciplines. While the research subjects and the clinical needs are provided by medicine, the theoretical underpinnings come from mathematics and statistics, and the methodological approaches from computer science and biomedical engineering, all forming critical components of the enterprise. Our recent work includes mapping and modeling of cerebral white matter hyperintensities, algorithm development for examining the shapes and sizes of brain structures and cortical atrophy. fMRI, pMRI, MRS, PET and SPECT are also currently being used as brain imaging modalities in various studies.

My Research Supervision


Areas of supervision

My research centres on the application of neuroimaging based approaches that seek to identify the clinical, lifestyle, genetic, and environmental determinants for brain ageing, mild cognitive impairment, dementia and other neuropsychiatric disorders. The neuroimaging techniques used in my research have include structural and functional brain imaging, major work has been performed largely with high resolution MRI, using such techniques as volumetric T1-weighted, FLAIR, diffusion tensor imaging (DTI), magnetic resonance imaging (MRS), susceptibility weighted imaging (SWI), perfusion imaging using exogenous contrast, and both resting state and activation fMRI.
