Professor Jim Piper Festschrift 2013

High-speed, high-contrast luminescence biosensing: Finding a needle in a haystack Detection, quantification, or localisation The Background-free imaging is achieved of particular cells or molecules – quickly, by our foundation technology known as sensitively and accurately – is fundamental “time-resolved luminescence assay”, that to both modern biomedical research and employs a long-lived luminescent probe industry: from understanding sub-cellular which glows for longer than non-target processes and biochemical pathways to the background cells (illustrated in Fig 1). early detection of diseases in clinical settings. Therefore the time-gating renders non- However, molecules that are altered as a result target cells, debris and other particles of a pathological condition are generally practically invisible. present in low numbers, and are extremely Our new generation of patented Super dots difficult to detect.

As an academic and A true leader and visionary, Professor Piper’s a university leader, most recent legacy to the Australian Professor Piper has research landscape was to establish the been at the forefront Australian Hearing Hub at Macquarie of research and higher University. Bringing together some of the education development country’s best researchers, educators and in Australia and service providers, to improve the lives of internationally. He has authored over 260 people who experience hearing loss and/or refereed journal articles and full-length language disorders, it was Professor Piper conference proceedings, and has who initially proposed the idea to the supervised to completion more than Federal Government, and whose approval 40 PhD students. Furthermore Professor for funding helped make the establishment Piper is inventor of 12 awarded patents, of the Hearing Hub a reality. with substantial experience in the Professor Piper has gained the enduring commercialization of research-derived IP. respect and admiration of those around Beginning with his Lectureship at him, not only as a leader and academic but Macquarie University in 1975 and also as a man of integrity and affability. throughout four decades of service, Now, as we prepare to say farewell to Professor Piper has made significant Professor Piper on his retirement at the contributions to Macquarie University, end of June, it is with great privilege that excelling as Director of the Australian we take this important opportunity to Research Council Special Research Centre recognise Jim and his many achievements. for Lasers and Applications, and Dean of Information and Communications Sciences. Professor Bruce Dowton Since 2003, under Professor Piper’s Vice-Chancellor Macquarie University leadership as Deputy Vice-Chancellor (Research), Macquarie’s Research, Higher Degree Research and Commercialisation programs have grown from strength to strength. The University’s increasing research performance has been exceptional with an increase in research outputs to rank fourth in terms of overall research at the highest level, first in cognitive science, environmental science and ecology. 3 Dr Mark Butler Head Teacher of Science Gosford High School, NSW National Education Convener Australian Institute of Physics Dr Mark Butler is currently Head Teacher of Science at Gosford High School, the National Education Convener of the Australian Institute of Physics and a member of the CUDOS Advisory Board, the MQ Photonics Advisory Board and the Macquarie University Science/Industry Advisory Board. Dr Butler completed a bachelor’s degree majoring in Physics at Macquarie University in 1978 and a Diploma in Education at the University of New South Wales in 1979. After working for a year in the physics teaching laboratories at the University of NSW, he returned to Macquarie University where he completed an honours degree in physics and a PhD in Plasma Recombination Lasers under Professor Jim Piper. In 1985 he worked as a tutor at Macquarie University and in 1986 was appointed Deputy Principal at the Australian International School, where he remained until taking up his current position as Head Teacher of Science at Gosford High School in 1997. A passionate advocate for engaging students in science, Dr Butler has written high school textbooks, study guides and journal articles and is a sought after speaker on science education. He remains above all else a dedicated science teacher and many of his students have achieved outstanding HSC results in physics and many have pursued careers in science. In 2007 he was appointed to the Advisory Panel for the Science National Curriculum and in 2008 he was appointed principal advisor and writer of the Senior Physics National Curriculum. Dr Butler was the recipient of the 2002 BHP/Billiton National Science Teachers Prize, the 2004 Premier’s Science Teachers’ Traveling Scholarship, the 2004 Prime Minister’s Prize for Excellence in Secondary Science Teaching, the inaugural NSW Scientist of the Year Award for Leadership in Secondary Science
