I am interested in developing and evaluating sophisticated statistical methods for modeling high-dimensional complex data. My current lines of research include (a) statistical analysis of multivariate time series, (b) exploratory factor analysis, and (c) bootstrap methods in psychological research. In addition, I am collaborating with substantive researchers on a number of topics: personality traits, smart phone based blood glucose monitoring, brain imaging techniques like fMRI and EEG.
