Biography

I am the Robert V. Hogg Professor of Statistics, a fellow of American Statistical Association, a fellow of Institute of Mathematical Statistics and an elected member of International Statistical Institute.
I started out as a theoretical statistician working on several topics on non-linear time series analysis including chaos. Through collaborative research with other scientists, I gradually realize and appreciate the use of nonlinear time series analysis and general statistical methods in addressing diverse scientific problems in ecology, epidemiology, hydrology, environmental studies, medical studies, etc. I have been fortunate to have collaborated with many inspiring and dedicated scientists here at Iowa and abroad. Much of my research work originates from attempts to understand and solve interesting scientific problems. At the same time, some of my work focuses on developing new general statistical methodologies. Developing computer packages, for instance in R, is essential to make new methods available to the public. Consequently, together with my students, I have spent substantial efforts in developing several R packages.
