Research Statement

Professor Toussaint directs the laboratory for the Photonics Research of Bio/nano Environments (PROBE), an interdisciplinary research group that pursues problems in both nanophotonics and biophotonics. With regards to the former, his lab pushes the limits of far-field optics by fully exploiting the properties of light such as its 3D polarization degree-of-freedom, its linear momentum (for optical trapping), and its angular momentum (both orbital and spin) to carry out optical characterization of single nanoparticles with high sensitivity. The biophotonics research pursued by PROBE relates to quantitative second-harmonic generation imaging of collagen-based tissues such as cartilage and the cornea, where quantitative markers are being developed for assessing tissue regeneration (wound healing), and the onset of various connective tissue diseases.

Research Interests

  • Plasmonic optical tweezers
  • Optical polarization and wavefront shaping
  • Advanced optical microscopy (biophotonics and nanophtonics)

Research Areas
