My research interest lies at the interface of applied probability, applied statistics and machine learning. My research is driven by collaborations with a few extremely talented and outstanding researchers.

Network analysis

This is a broad and burgeoning research topic. Specifically, I am interested in

• Random network models

  Collaborator(s):

  • Hosam M. Mahmoud from GWU
  • Tiandong Wang from SCMS

• Network inference

  Collaborator(s):

  • Jun Yan from UConn
  • Xiaojing Wang from UConn

• Community detection

  Collaborator(s):

  • Dipak K. Dey from UConn

Longitudinal data analysis

This is the primary focus of my current reserch. We are committed to developing novel statistical methods for assessing dementia risk in neurodegenerative diseases and related disorders. Specifically, we investigate missing data, measurement error and variable selection problems, and focus on the applications to Alzheimer’s Disease, Parkinson’s Disease and other neurodegenerative disorders.
