Description of Clinical Expertise
Neuroradiology and molecular imaging using positron emission tomographyDescription of Research Expertise
1. Evaluation of neuroinflammation using novel PET tracers.2. Evaluation of brain development and understanding the neuronal mechanisms underlying various neurocognitive functions and etiopathogenesis of various neurological-psychiatric disorders.
3. My particular expertise/strength lies in being able to integrate and use advance multi-modal structural and functional imaging, such as MRI/fMRI, DTI, PET, SPECT, etc., in guiding neurosurgery and for the evaluation of various neurological disorders, including brain tumor, epilepsy, and neurodegenerative/neuroinflammatory/neuroimmune conditions.
