I am interested in the following statistical areas: smoothing and semiparametric regression functional data analysis high dimensional multivariate response reduced rank/mixed effects models high dimensional covariance matrix: estimation and theory
My major scientific areas of interests are: aging research, in particular research related to physical activity and heart rate activity recognition with high frequency data collected from body sensors (pictures on right: Actigraph GT3X+ and ActiHeart devices) children growth structural and functional MRI
