About


My research involves the development and implementation of statistical methods, especially those that are highly dependent on computation. My principal area of interest is mixture model-based clustering and recent work includes the development of approaches for higher-order data, mixed-type data, and multivariate longitudinal data. I have a special interest in autism and aging, respectively.
