Research Interest

  • My main research focuses on the characterization of polymers at the single-molecule and/or nanoscale level via fluorescence microscopy and its derivates. My research is divided into two main sub-topic: 1) Characterization of polymer dynamics and polymer reptation by micro-rheology and/or particle tracking 2) Characterization of photo-physical properties of single conjugated polymer molecules by emission, excitation spectrum and lifetime measurement.

    During my research, I have been involved in the development of a STED microscope and a multiplane microscope which taught me a lot about optics and microscopy. In addition, I have been developing my own algorithm to analyse output images including particle detection, particle tracking, segmentation and other. I prefer evolving in an inter-disciplinary and international environment as I think it is the best environment to learn from and learn to others
