Research

My research focuses on developing new statistical methods and theory for dependent data with complex structures. My primary focus to-date has been in the field of statistical network analysis, where I have developed novel methodology and theory for high-dimensional statistical models of network data with dependent edges. I am working on new projects and research directions in profile monitoring and change-point detection in dynamical applications in medicine and biology.
