Fang Li Ph.D.

Associate Professor, Mathematical Sciences

Current Research

Prof. Li's principal research interest focuses on inference of stochastic processes including long-range dependence and time series, in which nonparametric kernel estimations are explored to estimate regression, autoregressive, density, and heteroschadastic error variance functions. Some of her ongoing projects involve comparing multiple time series, which has diverse applications in economics and finance. In collaboration with research groups from biological fields, she is applying nonparametric and general linear mixed models to real life data. Additionally, she has strong interest in extending the nonparametric approaches to survival and longitudinal data analysis.
