About me
I am a PhD candidate at the Delft Center for Systems and Control of the Delft University of Technology with the supervision of Prof. dr. ir. Michel Verhaegen and Prof. dr. Gleb Vdovin . Currently, I am working on the lensless imaging methods by making use of wavefront sensing techniques from adaptive optics. Other novel phase imaging approaches such as digital micromirror device (DMD) based phase retrieval are under development as well. With me, you can build a more sophisticated quantitative phase contrast imaging microscope for imaging the invisible specimen in the Smart Optics Lab. This project usually involves hands-on optical experiments, wavefront sensing technologies and computational imaging.
