Professor Berger's area of interest is biomedical optics, specifically the development of diagnostic spectroscopic and imaging methods. The group's present research is centered upon:
Raman (inelastic scattering) spectroscopy of bone, to estimate fracture likelihood nondestructively and noninvasively
elastic scattering analysis of single cells, to detect early and subtle transformations in response to stimuli
improved detection of bruising in dark-skinned individuals, to improve documentation of violence
