Clinical Interests
Functional MRI, presurgical planning, dementia
Research Interests
- Quantitating and modeling physiologic processes in normal and diseased states in the central nervous system through the use of imaging
- Application and development of advanced MR imaging technologies (e.g., diffusion, perfusion and fMRI) as well as advanced image processing and analysis techniques
- Elucidating the functional unpinnings of cognitive impairment in early stage Alzheimer's disease
- Development of functional imaging biomarkers for early diagnosis and monitoring of dementia
- Functional MRI as an aid to preoperative planning in patients with potentially resectable brain lesions
