Research Interest

My research interests have been in the area of Biophotonics, attempting to understand tissue fluorescence and light scattering in human tissue environment and to evaluate its use for diagnosis of disease. Recent focus lies in the areas of Fluorescence Mueller matrix imaging and spectroscopy, attenuation free fluorescence based diagnostics which include development of automated device for clinical use, development of fluorescence and photoacoustic diffuse optical tomographic reconstruction algorithms, frequency domain tomography for tissue diagnosis and fluorescence lifetime imaging in the ultrafast regime. Future interests are to explore ways to improve such diagnostic capabilities in order take it towards the desired goal of noninvasive and early detection of disease, specifically cancer.
