Fluorescence Lifetime Microscopy (FLIM) of intrinsic biomarkers has demonstrated an exceptional capability to non-invasively investigate the energetic and metabolic redox state of living tissues at the cellular level.

We develop novel approaches for fast FLIM imaging and label-free optical methods for metabolic imaging in stem cells and living tissues.
