Lab interests
Neurobiology: Application of fMRI methods to address neurobiological mechanisms underlying sensory information processing and plasticity in the human cerebral cortex. The primary interest is in understanding how the visual system uses multiple cortical areas to process a visual scene.
Clinical fMRI: These studies also involve research aimed at technical improvements in fMRI methodology to increase sensitivity and resolution, using real-time processing methods to carefully control and monitor subjects' stimuli and responses, and to perform fMRI statistical image analysis on-line in real-time.

fMRI as a Quantitative Imaging Biomarker: We are actively involved in how to improve the quantitative reproducibility of fMRI in order to make it a more robust imaging tool. This is part of an international collaborative effort of the Quantitative Imaging Biomarker Alliance (QIBA) sponsored by the Radiological Society of North America (RSNA). Our efforts focus on identifying and reducing sources of variance in fMRI mapping by establishing practical quantitative quality control criteria and developing image analysis procedures that emphasize brain activity levels rather than MRI noise signal fluctuations.
