About Me

I am currently an assistant (tenure-track) professor in the Department of Statistics at the University of Pittsburgh, with a joint appointment in the Department of Psychiatry. I obtained my PhD from the Department of Statistics at UC Davis in June 2012 under supervision of Professor Hans-Georg Müller, and I got my BS degree from the School of Mathematical Sciences, Peking University, China , in June 2007.

Research Interest

My statistical methodological work focuses on functional data analysis, longitudinal data analysis and network modeling, including

  • Nonparametric mean and covariance estimation for different functional data designs.
  • Functional principal component analysis and its variations.
  • Regression, conditional distribution and quantile estimation for functional, longitudinal data, and relevant hypothesis testing.
  • Classification and clustering for functional and longitudinal data.
  • Model based network estimation and inference.

I am also working on various applied statistical problems, including brain functional connectivity study and multimodal neuroimaging analysis for mental disorders, using model based network inference, high-dimensional statistical learning and functional regressions.
