In the Laser Analytics Group, I am working primarily on an automated, drug-screening microscopy platform, based on time-gated FLIM and incorporating supercontinuum excitation. I am interested in applying this technique to study neuro-degeneration in live C. elegans worms, to investigate chromatin condensation and to design drug-screening assays.
