Research Interests

Protein folding and aggregation. Our main focus is to use single molecule confocal microscopy techniques like fluorescence resonance energy transfer (FRET) and fluorescence correlation spectroscopy (FCS) to monitor protein dynamics. In particular, we want to lay special emphasis on how macromolecular crowding and confinement influence the folding and aggregation of proteins.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    

(a) Confinement (b) Macromolecular crowding. The unfolded protein is shown in red while the blue sphere represents its native form. The dark spheres in (b) are the inert macromolecular crowders. (Figure adapted from Zhou, Annual Reviews of Biophysics, 2008)
