Cryo-EM is becoming popularity in structural biology. This is because the technique allows observing specimens in their native environment without being stained or fixed, which can lead to functionally irrelevant conformational changes. It suits for studying both the structure and dynamics of large proteins and protein complexes. The resolution of cryo-EM images is improving significantly due to the hardware development in recent year. A virus structure obtained by cryo-EM is already at a resolution 3.3 Å that can be interpreted in terms of an atomic model.


Current major projects include:
  • Optimisation of amorphous carbon films
  • 3D data collection and reconstruction of virus by Tomography
  • Particle structure analysis on the function of the Hcp GP96 protein
  • Electron crystallography of 2D crystal analysis on membrane proteins

My research is focusing on using state-of-the-art electron cryomicroscopy to understand the structure and functions of protein and macromolecular complexes. I am also interesting to develop and apply the new methodology in the field.
