My research interests are (i) ultrafast coherent spectroscopy of semiconductor nanostructures, microcavities, and semiconductor optical devices. (ii) application of optical spectroscopy and microscopy to the life-science, including the techniques of coherent Raman scattering (CRS) microscopy, fluorescent resonant energy transfer, label-free optical biosensing.
Currently I am working on
- Developing an unsupervised hyperspectral image analysis method and software to analyse CRS data, which is also suited for Raman and fluorescence.
- Improving the imaging speed and spatial resolution in hyperspectral CRS
- Applying CRS to the life sciences, including areas of lipid metabolism, cell cycle, and stem cells
- Imaging of plasmonic and dielectric nanoparticles in cells using CRS, resonant four-wave mixing, and photo-thermal contrast.
- Measuring and understanding exciton dynamics in low-dimensional semiconductors like quantum dots and platelets
- The coherent coupling of excitons via photonic cavities
- The electrodynamics of resonators and waveguides developing the resonant state expansion
