Current projects Brillouin microscopy Brillouin microscopy recently emerged as a non-contact technique to probe the mechanical response of biological materials. SHG imaging of connective tissues Second-harmonic generation imaging of collagen architecture and biomechanics in connective tissues. 2P imaging of carbon nanotubes Multiphoton imaging of single-walled carbon nanotubes in the near-infrared as luminescent probes. Past projects Super-resolution brain imaging In vivo STED and shadow imaging (SUSHI) of dendritic spines and the brain extracellular space. PSF simulation and Adaptive optics Vectorial simulation of the point-spread function (FASER) and adaptive-optics aberration correction for deep STED microscopy. Interferometric SHG Interferometric SHG (I-SHG) measures the phase of the second-harmonic signal to reveal the polarity of non-centrosymmetric structures such as collagen and microtubules.
