Hello and welcome to my webpage. I am Professor of Statistics and Chair
of the Statistics and Bioinformatics Group in the Institute of
Fundamental Sciences at Massey
campus in Palmerston
Zealand. I am also the current President of the New Zealand Statistical Association.
For information on papers that I currently teach, see the Massey paper
codes under the Teaching heading in the panel on the left. Access to
information on those papers is available throught the Stream learning environment.
If you are looking for advice on which statistics paper(s) to take,
then feel free to contact
me. If you are considering doing Honours or a PhD in
Statistics and think that you might like to be supervised by me, then
read about my research below.
I have a variety of research interests. These include:
I have long been interested in kernel smoothing problems, and in
particular spatially adaptive methods for multivariate data. My current
work in this area includes kernel estimation of relative risk functions
in geographical epidemiology, with former PhD student Tilman
Davies (the latter now a lecturer at the University of Otago). Recently I have been working in collaboration with Berwin
Turlach on weighted density esimation and kernel
deconvolution problems. I have also become interested in constrained
spline smoothing, again working in conjunction with Berwin, and also with former Honours student Khair bin Jones.
Biostatistics and Applied
I have a keen interest in the development and application of
statistical methods in medicine, particularly epidemiology and
I am currently working withProfessor Bill Morgan (Lions
Eye Institute, Western Australia) on some challenging
problems for ophthalmic data collected from glaucoma patients. I am also a Principal Investigator in Massey's Infectious Disease Research Centre (IDReC), where my work includes modelling patterns of foot and mouth disease in Vietnam with epidemiologist Prof Mark Stevenson and former PhD student Kate Richards, and estimation of spatial risk (as discussed under Smoothing Methods above).
my interests in smoothing, networks, and geographical epidemiology, I
have an evolving interest in spatial statistics. Much of Tilman Davies' later work was in this area.
I am Associate Investigator on a New Zealand Royal Society Fast Start Marsden Fund grant
entitled "Smoothing and inference for point process data with
applications to epidemiology" for 2016-2019. The Principal Investigator
Statistical Modelling and Inference in Transportation Science
generates a huge range of fasinating problems. I'm currently focused on
network tomography (in essence, statistical methods for learning about
high dimensional properies of network traffic flows based on lower
dimensional observations), and modelling and inference for
day-to-day dynamic traffic networks, with Professors David Watling, Giulio Cantarella, Hong Lo and Mike Smith. I was awarded a New Zealand Royal Society Marsden Fund grant
for 2015-2019 to work in this area. Iranian PhD student Ahmad
Mahmoodjanlou is working with me on this project. He is co-supervised
by Dr Katharina Parry, who recently joined Massey as a Lecturer in Statistics.
In addition to these medical areas, I have a
general interest in
the application of statistical methods. Indeed, one of the great things
about working in statistics is that
I've had the opportunity to look at a diverse range of intriguing
problems from a wide variety of areas, from archaeology, to finance, to
I was the recipient of the 2014 Littlejohn Research Award, the New Zealand Statistical Association's premier research award.
