Elinor Ytterstad

Elinor Ytterstad is an Associate Professor in the Department of Mathematics and Statistics at UiT The Arctic University of Norway. She actively contributes to the Complex Systems Modeling (CoSMo) and Statistics and Data Analysis research groups, focusing on interdisciplinary statistical applications.

Her research centers on biostatistics and epidemiology, with expertise in survival analysis, statistical modeling of health outcomes, and public health applications. Key areas include widowhood mortality dynamics, dietary patterns and metabolic syndrome relationships, occupational health hazards (particularly noise and hand-arm vibration exposure), and substance use disorder comorbidities. She employs advanced statistical techniques to analyze large population datasets from Norwegian and Australian cohorts, aiming to uncover causal relationships and predictive factors for health outcomes.

Analysis of her recent publications reveals consistent application of frailty models and multivariate analysis to critical health issues. Major trends include bereavement mortality studies utilizing Norwegian population data, dietary pattern analyses across demographic strata in the Tromsø Study, and occupational exposure assessments in Australian workforce surveys. Her work frequently bridges statistical methodology with practical public health interventions, demonstrating particular strength in translating complex models into actionable health insights.

Dr. Ytterstad maintains active involvement in statistical education through workshops like the 2018 R Commander session, supporting computational statistics adoption among researchers.
