Our current research interests are in bio-optics where various light scattering techniques and spectroscopies are used to probe biological systems. We are currently developing static and dynamic light scattering methods to look inside materials that multiply scatter light. Examples of such materials include tissue, colloids, emulsions, and foams. We are developing algorithms to reconstruct images of the optical and dynamical properties of these opaque materials on different lenght scales. This imaging modality, known as diffuse optical tomography (DOT ), may be used in medicine for optical mammography, hopital bedsidd monitoring of brain heamtomas, diagnosis of ischemic versus bleeding strokes, imaging of tissue blood oxygen saturation and flow, and identification of cancerous lesions. An exciting new application of DOT is the study of brain function.
