Research Interests

My research interests are broad and wide-ranging. Fundamentally I am a computational statistician with interests in nonparametric inference, data mining and data visualization. Within this general framework, I have specific interests in time series analysis, function and curve estimation including splines, and inference under order restrictions. My interest in data mining includes interest in methods for streaming data and massive data sets. I have been recently pursuing work in social networks and text mining. Specific applications that interest me are modeling acute effects of alcohol use from a public policy perspective, intrusion detection into computer systems, and statistical methods used in climate studies.
