Theodore R Holford PhD
Susan Dwight Bliss Professor of Public Health (Biostatistics) and Professor of Statistics
The current research in which Professor Holford participates involves the development and application of statistical methods in health research. This work focuses on methodology for the analysis of spatial and temporal trends in disease.
- Modeling Interventions for Lung Cancer Mortality (CISNET)
- Asthma Severity in Children and Fine Particle Composition
Gene and Testicular Cancer Risk
- Spatial Risk Model for Ixodes Scapularis-bourne Borrelia
- Intervenable Host Leishmania (Viannia) Interactions.
Professor Holford's current research extends his work with age-period-cohort models for population disease trends to analyses that quantify the impact of exposure to known risk factors on those trends. His work measuring the impact of cigarette smoking on lung cancer mortality is an example of this approach and it is part of the Cancer Intervention and Surveillance Modeling Network (CISNET). These models are useful in planning disease control strategies. Another focus of his research is the development of methods for studying the impact of environmental exposures on disease risk using Geographic Information Systems (GIS). These applications include the effect of exposure to traffic on asthma symptoms, and the prediction of areas that have habitats that are compatible with vectors for specific microbial diseases.
