Professor Renate Meyer

Biography

I am an applied Bayesian statistician. After obtaining an MSc in Mathematics ( for which I was awarded the Springorum Denkmuenze) from the RWTH Aachen, Germany, I worked as a research scientist in the Department of Medical Statistics from 1988-1993 and did a PhD in Mathematical Statistics also at the RWTH Aachen. I then took up a lectureship in Statistics at the University of Auckland in 1994.

Research | Current

I am working on applied Bayesian inference and MCMC methods with interdisciplinary research collaborations and applications in astrophysics, econometrics, fisheries, marine ecology, medicine and engineering.

Contributions to the development of MCMC methodology have been published in Statistics and Computing, Computational Statistics and Data Analysis, and Computational Statistics.

My ongoing collaboration with astrophysicists Nelson Christensen, Carleton College, started in 1998 when we pioneered the MCMC approach to gravitational wave and cosmic microwave background radiation data analysis. This started a Marsden and NSF funded research program which led to world-wide collaborations and ground-breaking contributions to the development of MCMC-based data analysis strategies for LIGO with a series of publications in top-ranking Physics journals PRD and PRE. Some of these papers build the foundations of the MCMC techniques used to estimate the parameters of the two binary black hole mergers detected on September 14, 2015 by the Advanced LIGO interferometers and are cited in the parameter estimation paper that accompanied the famous detection paper by the LSC, published in Physical Review Letters on Feb. 11, 2016.

I am chair of the NZ Astrostatistics and General Relativity Group, which comprises statisticians and astrophysicists from the University of Auckland, Victoria, Canterbury and Otago. In 2019, we joined  the LISA (Laser Interferometric Space Antennna) Consortium that leads the European Space Agency mission of observing gravitational waves from space, see also the NZ Herald article.

In econometrics, my collaboration with Prof Jun Yu, Dept. of Economics, Singapore Management University, concentrates on a Bayesian approach to stochastic volatility models for financial time series. Our frequently cited papers have been published in JBES, The Econometrics Journal, and Econometric Reviews.

Collaborative research in Fisheries and Marine Science with A/Prof Russell Millar started in 1996 and established the Bayesian approach to fisheries stock assessment using state-space models. This method has become the standard for analysing biomass dynamics models and our papers published in Applied Statistics and CJFAS, one of the world’s top fisheries journal, have received close to 200 citations. Related collaborative research with A/Prof Mike Dowd, Dalhousie University, in Marine Ecology, is in Bayesian statistical data assimilation using state space models where we have developed particle filtering methods for high-dimensional spatio-temporal ecosystems. Publications are in Ecological Modelling and Envirometrics.

A further main focus of my research is in Medical Statistics with recent papers on Bayesian approaches to analysing stratified survival data, time-dependent frailties and copula models for multivariate survival data. Papers have been published in Statistics in Medicine, CSDA, and JRSSA. Last not least, Bayesian models for stratified survival data had significant applications in Engineering, where we developed new hierarchical models for pipe failure times of water distribution systems.
