I have established strong links with my research collaborators nationally and internationally. Many of my collaborations began while at the EMBL in Heidelberg and I am extremely proud that they continue to this day (eg. with Professor Marino Zerial, Max Planck Dresden, Professor Jean Gruenberg, University of Geneva). My involvement in the ARC Centre of Excellence in Convergent Bio-Nano Science and Technology has opened up some of the exciting new linkages that form the basis of the current proposal. Together with Drs. Angus Johnston (Monash) and John McGhee (UNSW) we have translated our 3D EM data obtained from whole cell ultrastructural analyses into a Virtual Reality (VR) experience. This collaboration has been hugely successful and very popular. But this is only the beginning and we can now envisage a new era in which we can populate these simulations with molecular data to examine biological processes, and test key hypotheses in this interactive 3D environment, which is a feature of the Laureate Fellowship program.

I have established strong links with outstanding international collaborators, such as Professor Ludger Johannes, Curie Institute, and Prof. Tom Kirchausen, Harvard University, and the proposed program will strengthen and extend these links. My involvement in the ARC Centre of Excellence in Convergent Bio-Nano Science and Technology has opened up some of the exciting new linkages that form the basis of this proposal. Together with Drs Johnston (Monash) and McGhee (UNSW) we have translated our 3D EM data obtained from whole cell ultrastructural analyses into a VR experience. This collaboration has been very fruitful and our success will be leveraged to extend these simulations to in vivo models and different tissues.

I have made seminal contributions driven primarily by the research interests of my collaborators (e.g. Miaczynska et al, Cell 2004, 407 citations, FWCI 8.22; Takasato et al, Nature 2015, 362 citations, FWCI 13.9). These have included highly cited seminal papers on crucial conserved endocytic proteins (Chavrier et al, Cell 1990, 963 citations; Bucci et al, Cell 1992, 1057 citations), a collaboration which still continues with recent papers in Nature (Murray et al, 2016, 44 citations, FWCI 2.88) and eLife (Hsu et al, 2018, 7 citations, FWCI 2.17). Many of these required development of new techniques. For example, I developed new quantitative electron microscopic techniques to identify nanodomains in the inner leaflet of the plasma membrane, resulting in high profile publications in Nature Cell Biology (Roy et al, 1999, 384 citations; Prior et al, 2001, 400 citations), the Journal of Cell Biology (Prior et al, 2003, 495 citations, FWCI 7.81), and Proceedings of the National Academy of Science. Over the following years, the method has been used in numerous studies by other groups and has resulted in high impact breakthroughs including dissection of the nanoscale organisation of lipid-anchored signalling proteins in the plasma membrane (eg. Zhou et al, Science, 2015; Zhou et al, Cell, 2017).
