Associate Professor Irene Hudson

Email contacts: *********************************************************** Please use irenelena.hudson@gmail.com AND irene.hudson@unisa,edu.au *********************************************************** I am also often avaialable on 830-20527 (ARCCS Consulting Room) and Phone 830 27093 (Ph D student office) Associate Professor Irene Hudson joined UniSA on February 9, 2006, as Director of the Statistical Consulting and Research Services (SCARS) and Academic Leader of Statistics. Previously Associate Professor Hudson was Director of the Research Centre for Health Care Technology NZ (1999-2003) and Senior Lecturer in the Mathematics and Statistics Department, the University of Canterbury (UC), Christchurch, NZ (1997-2006). Irene has an extensive publication record in the areas of biostatistics, causal inference, statistical phenology, ecological inference, health environmetrics and wood informatics. She is widely cited for her contributions to health sciences, biostatistics, global climate indicators and wood science.

Her vision is to build a strong mathematical statistical research and postgraduate profile at City West. She will build collaborative research links with maths (CIAM, ISST, MISG), industry, health sciences, business and information sciences. Associate Professor Irene Hudson believes a strong undergraduate base will build a stronger postgraduate base and shall work towards this and increased overseas links in teaching and research. Her intention is to change SCARS to ARCCS - Advice, Research, Collaborative & Consultative Statistics - with a new logo!

Associate Professor Hudson has an Adjunct position in the School of Forest & Ecosystem Science, University of Melbourne (2005 - 2007) in recognition for her statistical methods in phenology research and for ongoing wood informatics research (1993 - 2006). Recent phenological statistical work, linked to global climate change (2000 - 2006) adds to global climate/health markers and mapping research, linking Australasia with European research (EU Phenology Network, International Governmental Panel for Climate Change (IPCC 2007)).

Irene is one of a few statisticians working on wood fibre micro-structure. In 1993 -1997 as Sub-Program 1.2 Leader at the CRC for Hardwood Fibre and Paper Science, University of Melbourne, she led a team to model wood micro-structure in Eucalyptus from fibre image data - the first group to establish within-tree-ring partitions translatable to a new coordinate system for whole trees (Eucalypts). This work led to a coordinated change in wood quality (WQ) sampling protocols in Australasia and was crucial to the calibration of SilviScan2 (CSIRO), an international device for rapid WQ testing. The Wallenberg Prize (“Nobel Prize” in forest research) was awarded in 2001 to SilviScan’s inventor, Robert Evans. Irene was the first statistician to present at the International Assoc of Wood Anatomists (1996, Darwinian Linnean Society, London).

From 1989 – 1993 Irene was Senior Statistical Consultant at the Statistical Consulting Centre at the University of Melbourne, and Lecturer in Medical Statistics, Statistical Inference and Categorical Data Analysis at the University of Melbourne and also at La Trobe University. She worked primarily with external clients (Kraft, GLAXO, Hoechst), Hospitals (Royal Children’s Hospital, Royal Melbourne Hospital, Royal Talbot) and Government departments (Fisheries) and also with University of Melbourne departments (Economics, Law, Medicine, Dentistry, Paediatrics).

As Head of the Biostatistics Unit, the University of Melbourne (1982-1989), Irene led the first statistical research group in Australia to create a paediatric diagnostic related groups (DRGs) case-mix cost, length of stay system. To that date only adult DRG's were in place. Associate Professor Hudson has continued since then (1982 - 2006), both theoretical statistical research and applied research in medical biostatistics. Irene's current health sciences and bio-statistical research areas are psychometrics (brain image prints of character and temperament), clinical trials research, survival methods with non-compliance (with Harvard University), Parkinson’s disease, epidemiology, health environmetrics, bioinformatics (molecular docking, gene expression), ICU and speech/language therapy. Irene is on the Editorial Board for Statistical Methods in Medical Research etc.

At her previous employ at the University of Canterbury (UC), Mathematics and Statistics Department, Irene closely supervised 20 postgraduate students both within mathematics and across disciplines (elec- and mech- engineering, forestry, physics, psychometrics, epidemiology, biostats, history, environmental science and political science).

On March 1, 2006 Irene was offered an appointment as Adjunct Associate Professor at the University of Canterbury, Mathematics and Statistics department (2006-2009). She remains an active researcher and postgraduate supervisor for the University of Canterbury and the Van der Veer Institute for Parkinson’s and Brain Research, the UC Research Centres of Bio-Engineering and the Wood Technology Research Group. Hudson is an Associate Editor (AE) of a new Journal, Case Studies in Business, Industry and Government Statistics www.bentley.edu/csbigs.
