research

Time series analysis and forecasting: I study the modeling and the prediction of univariate and multivariate time series; ARIMA models; state space models; smoothing and shrinkage methods; time series models for count data; the detection of outliers and adaptive estimation, and the reduction of dimensionality in multiple time series.

Statistical methods for process improvement: The results of well-designed experiments can tell us how to improve processes. I study and apply sound design principles to conduct industrial experiments, economic/business field experiments, and animal experiments. Statistical surveillance of processes can tell us whether process characteristics have changed. I study statistical control chart methods (CUSUM charts, robust control charts) for time-change detection.

Application of statistical methods in the health sciences, especially in anesthesiology and ophthalmology: My work with the Department of Anesthesiology at the University of Iowa deals with the analysis of patient data to improve the managerial aspects of care. My work with the Center for the Prevention and Treatment of Visual Loss at the Iowa City VA Health Care System includes the design of animal studies to study traumatic brain injury and the analysis of the resulting data, the development of statistical methods for the detection of functional and structural changes of the eye, and the analysis of nerve damage in the eye due to diabetes.
