Doctor Timothy Stait-Gardner

NIF Facility Officer,
Dean's Unit School of Science

Biography

Dr Stait-Gardner obtained his PhD in theoretical physics from the University of Western Sydney (UWS) in 2006. His PhD examined thermodynamics in the curved spacetime of general relativity. He was associated with the Fusion Research Group at UWS for three years beginning in 2000. His topic of study at the time was laser confinement and he worked specifically on the problem of deriving the form of the electromagnetic field from the vector potential for Laguerre-Gaussian Beams. Since completing his PhD, Dr Stait-Gardner has worked closely with the Nanoscale Organisation and Dynamics group headed by Professor Price on a variety of projects in Nuclear Magnetic Resonance/Magnetic Resonance Imaging (NMR/MRI). Dr. Stait-Gardner is currently National Imaging Facility (NIF) officer at UWS. He has worked on collaborative projects with a variety of groups (from UWS, UNSW, USyd, CSIRO). These projects have ranged from assessing various contrast agents to determining the mechanical properties of skin, to investigating whether inorganic phosphorus regulates the rate of leaf photosynthesis and growth during phosphorus starvation.
