Senior Engineer at Instrumentation Laboratory, A Werfen Company
Our group develops optical technologies for capturing 2D, 3D and hyperspectral images of cells in fast moving fluids. These systems exploit spectral, angular and polarization degrees of freedom in the optical signal, as well as recent advances in microoptics, high speed light sources and cameras. In addition to spatial and spectral information, we are also interested in performing quantitative measurements of other physical characteristics of cells, such as volume, protein mass, and oxygen tension. Resolving the distribution of various measurable parameters enables better understanding of subtle differences in the response of each cell to its environment. We are currently using these measurements to differentiate pathological blood cells and to study the life cycle and kinetics of immune cells.
