Research summary

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
