Overview

Dr Peter Baker is a Senior Statistician, Senior Lecturer and Senior Consultant with the Queensland Clinical Trials and Biostatistics Centre, School of Public Health, University of Queensland.

He holds a position as a Senior Biostatistical Consultant and Senior Lecturer in Statistics at the School of Public Health.

Peter's current research interests include:

  • graphical models for multivariate data in epidemiology,
  • investigating the appropriateness of statistical methods (seasonal ARIMA and ZIP models) for assessing policy interventions in seasonal time series data including application to the Queensland Government Drink Safe Precincts study with the Centre for Youth Substance Abuse Research (CSYAR),
  • efficient statistical computing using R for the workflow of data analysis,
  • reproducible reporting using R, markdown and related tools,
  • statistical methods for modelling trajectories of alcohol consumption in youths,
  • analysis of longitudinal study data relating cardiovascular risks to behavioural and demographic traits, and
  • MCMC methods for Bayesian analysis of multilevel health studies in developing countries.

Research Impacts

Peter is a highly experienced statistical consultant and researcher who worked at CSIRO Mathematics, Informatics and Statistics for 20 years before joining the School of Population Health at the University of Queensland. During his time at CSIRO, he worked in a range of areas including agricultural research, bioinformatics and quantitative genetics. Highlights: developed novel Bayesian methods for assessing marker dosage in sugarcane and other polyploids and applied false discovery rate methods to QTL analysis and microarrays.

In addition to collaborating with a range of applied scientists to advance scientific knowledge by employing standard and cutting-edge statistical methods, several projects have had practical significance to industry including timely alerts to graziers when drops in temperature are dangerous for lambing, improved soil moisture estimation for cotton production and enhancing quantitative methods for sugarcane breeding. Recent collaborative work has informed public policy on drink safe precincts and alcohol related problems, effectiveness of mosquito nets and the effect of sunscreen to prevent skin ageing.

When it can improve research outcomes, Peter is keen to apply new statistical methods to epidemiology, health and medical studies in order to extract the maximum information from study data. He is also an advocate for reproducible research and efficient statistical computing using the R statistical and graphics system.
