Functional Optical Imaging Laboratory

Research Highlights

Laser Speckle Contrast Imaging

We develop blood flow imaging systems to study the effects of ischemic stroke on cortical perfusion and to better understand the underlying physics of dynamic light scattering.

Multiphoton Microscopy

We design high-resolution nonlinear microscopes to study the three-dimensional vascular and neuronal structures of the cortex at depths pushing the limits of optical imaging.

Modeling Light Propagation

We simulate photon propagation through large tissue geometries in order to understand the effects of scattering and its influence on imaging depth and resolution.
