Noelle I Samia

Associate Professor of Statistics and Data Science

Ph.D., 2006, University of Iowa

Research Interests

Time-series analysis; Nonlinear time-series modeling with emphasis to threshold models; Statistical inference for infectious diseases and epidemiology; Statistical ecology; Statistical applications to biomedical research.

Research Statement

My research interests focus on introducing and developing new statistical linear and nonlinear (threshold) models. My work is both, theoretical and applied in nature. Through cross-disciplinary collaborations, these advanced and often new statistical methodologies are tailored to each specific application with the aim of explaining the dynamics of complex biological systems, particularly in the areas of infectious diseases and epidemiology, statistical ecology, and biomedical research.
