Research Interests

Quantitative microbial risk assessment of food systems • near-infrared spectroscopy of biological materials  • biosensor development for flow through liquid food systems • statistical process control

Current Research

Near-infrared Spectroscopy of Biological Materials

Using near-infrared spectroscopy (NIR) Dr. Donahye creates methods and models for quality evaluation of food and forest products. These have resulted in the use of NIR for process monitoring, evaluation and control and are key elements in design considerations for overall processing cost reduction.

Quantitative Risk Assessment

Dr. Donahue has been involved in the area of quantitative risk assessment. Dr. Donahue’s experiences related to risk assessment and modeling are: National Academies of Science Committee, Scientific Criteria for safe food (2001-2003); US-EPA, Science Advisory Board, Computational Toxicological Framework for Risk Assessment (2003), Microbiological Risk Assessment for drinking water (2004-present); US Army-CHPPM, task force for anthrax threat models (2003-present); and an AOAC International, Best Practices for Microbiological Methods (2004-present). In these risk assessment venues, Dr. Donahue contributed his expertise to the exposure assessment and dose response portions of risk assessment where he can capitalize on his strengths in statistics and Monte Carlo simulation modeling.
