Research Interests

Functional neuroimaging (e.g, with fMRI and PET) has become an important part of neuroscience research. However, the use of these tools in clinical environments has been hampered by such limitations as the need to sedate children before scans and the inability to transport intensive care patients to fixed scanners. Functional imaging through Diffuse Optical Tomography (DOT, which measures blood content and oxygenation using infrared light through the same principle as a pulse oximeter) has the potential to supplement current imaging technologies and be an important clinical tool. In the lab of Dr. Joseph Culver, I work on many aspects of DOT development including engineering the system and developing more advanced imaging algorithms. Current imaging projects include mapping retinotopy in the adult visual cortex and measuring resting-state functional connectivity.
