Professor David McKenzie
Prof David McKenzie’s work in Biophysics began with a collaboration between Drs Peter French and Keith Stanley of the St Vincent’s hospital Centre for Immunology where he looked at the effects of non ionising radiation on cells and proteins using array technologies for gene expression. A collaboration with Dr Natalie James of Ventracor and then of Cochlear Ltd led to the introduction of polymers and ion beam modified polymers into implantable medical devices.
During his time at the University of Sydney, Prof McKenzie directed research in renewable energy, which culminated in the development of high performance evacuated tubular collectors commercialised in Japan as the high efficiency evacuated all glass solar collector that is now sold throughout the world. Prof McKenzie initiated and directed research in electron microscopy in the School of Physics (through his roles as Director and Deputy Director of the Australian Key Centre for Microscopy and Microanalysis).
The funding available through the Key Centre for Microscopy and Microanalysis enabled him to resource his work on the microstructural investigation of structure and bonding in solids based on electron energy loss spectroscopy (EELS) and energy filtered electron diffraction . It was the availability of these techniques that led him to the discovery of tetrahedral amorphous carbon as a new and distinct structural form of carbon. Prof McKenzie was one of the first practitioners of the Density Functional Theory method for simulating the structure of condensed matter systems (as a collaboration with Prof Michelle Parrinello then of the Max Planck Institute Stuttgart).
Prof McKenzie has been a CI in the CQCT since its inception and manages the University of Sydney node of the CQC2T. His laboratory includes UV-IR ellipsometry, magnetron, RF plasma and cathodic arc based deposition systems as well as x ray photoelectron spectroscopy (XPS), Kruss surface energy analysis, Digilab FTS7000 IR spectrometer with ATR, and surface profilometers. Professor McKenzie is taking an active role in the New Australian Centre for Nanoscale Science and Technology (AINST) as a member of the School of Physics Research Strategy Committee. This infrastructure and stimulating intellectual environment of the School of Physics will support the proposed research in drug delivery materials.
He is formally affiliated with the Lifehouse through his collaboration with A/Prof Suchowerska. During this collaboration, Prof McKenzie has made important contributions and innovations in the field of Medical Physics and Radiation Biology. These include the development of an innovative solution to small field dosimetry through the development of FODTM, an innovative solution to the problem of eliminating Cerenkov radiation from fibre optics through the use of an air cored light guide.
