 My bachelor's degree was in Mathematics from
the University of Washington, Seattle
in 1972, I received a Master's Degree in Statistics from the California State
University as Hayward in 1974, and
a Ph.D. in Statistics with a minor in Mathematics from the University of Minnesota,
Minneapolis
in 1979. I joined the Department
of Statistics at UC Davis in 1979 and was chair of the graduate group in Epidemiology at
UCD from 1997 to 2002. I joined the Department of Statistics at UC
Irvine in 2005.
My research interests are eclectic. I am mainly interested in
developing Bayesian statistical methods for biostatistical and
epidemiologic applications. I am currently involved with collaborative
efforts to develop Bayesian nonparametric and semi-parametric methods
in survival analysis, longitudinal analysis and joint modeling of
survival and longitudinal data. I also
work on diagnostic screening protocols and methodology when no gold
standard test is available. This includes
ROC curve estimation, development of models and methods for
longitudinal screening data including change-point models that account
for disease occurrence during the study, and general methods for
combining information to improve diagnosis. I
have also been involved with the development of risk analysis models,
sample size determinations in the context of risk assessment and
models, longitudinal and spatial methods for predicting global foot and
mouth disease, and for the analysis of hormone profile data. I also have a general interest and expertise in
the areas of regression diagnostics, prediction, multivariate
analysis, models for correlated binary data, asymptotics
and Markov chain Monte Carlo methods.
My curriculum vitae gives more details.
At UCI, I have taught courses on longitudinal data analysis (STA 212),
undergraduate probability (STA
120A), masters level statistical theory (STA
200BC), Multivariate Analysis (STA 240),
Bayesian Theory, Methods and Data analsysis (STA 225), Bayesian Nonparametrics (STA 226) and Ph.D.level Mathematical
Statistics (220B).
I have written a Bayesian book with my friends Adam Branscum, Ron Christensen and Tim Hanson. The book is intended for a broad audience
of graduate students in all areas of science, including Statistics. You can find information about the book at
